In another inventive embodiments, when joining mirror for the first time, the controller of these electric excitation glasses can be programmed by ophthalmologist oculist or technician at first, and afterwards when patient's needs change, then can carry out reprogramming so that different rectifications to be provided to same controller or its parts.The controller of this electric excitation glasses can be taken off from these glasses, in checking process, be placed in the controller/programmable device (being shown in Fig. 1 and Fig. 2) of dioptric apparatus and reprogramming, or do not take off and carry out reprogramming by dioptric apparatus in position from these electric excitation glasses.In this case, the controller of these electric excitation glasses may have the architecture of for example a kind of FPGA (or field programmable gate array).In this inventive embodiments, this electric excitation eyewear controller can forever be structured in these glasses, and only need be connected with the interface of this dioptric apparatus, and wherein this dioptric apparatus is to the instruction of this FPGA issue reprogramming.The parts of this connection may comprise the external AC power supply of this electric excitation eyewear controller, and this power supply is by in this dioptric apparatus/phoropter of embedding, or the AC adapter that is embedded in its controller/programming unit provides.

In another inventive embodiments, these electric excitation glasses play the effect of dioptric apparatus, and are only comprised the numeral and/or the analog interface of this electric excitation eyewear controller by the external equipment of ophthalmologist oculist or technician's operation.Like this, the controller of these electric excitation glasses also can be used as the controller of this dioptric apparatus/phoropter.In this embodiment, can utilize the processing electronic equipment that needs, thereby after the best rectification of rule of thumb having determined this user, change is added in the voltage of this grid array on these electric excitation glasses, and utilizes these data that these electric excitation glasses are carried out reprogramming.In this case, this patient can observe visual acuity chart once more by his electric excitation glasses in checking process, and this patient may not perceive when he when selecting best corrective prescription, just the while has been carried out reprogramming with the method for electronics to the controller in their the electric excitation glasses.

The embodiment of another kind of innovation has adopted the automatic dioptric apparatus of a kind of electronics, the automatic dioptric apparatus of this electronics can be used as first step and/or is used for combining with this electric excitation dioptric apparatus (illustrated in figures 1 and 2), the example of the automatic dioptric apparatus of this class has such as automatic dioptric apparatus of Humphrey and the automatic dioptric apparatus of Nikon, but be not limited to these, they have been carried out exploitation or have improved, so as to be provided for electric excitation lens of the present invention can be compatible and the feedback of having programmed.When patient or wearer had on the electric excitation glasses of he (she), it is unusual that described innovation embodiment just can be used to measure people's refractive power.This feedback is fed in controller and/or the programmer automatically or manually, then to user/wearer's electric excitation glasses correct, programming or reprogramming.In the embodiment of described innovation, patient's electric excitation glasses can be corrected on demand again and the refractive power that need not carry out comprehensive eye examination or eyes is measured.

At some in other the inventive embodiments, by patient's electric excitation lens, can be with its vision correction to 20/20.In most situation, this is to realize by the refractive power unusual (myopia, hypermetropia, astigmatism and/or presbyopia) of correcting people's conventional.At some in other the inventive embodiments, except the refractive power unusual (myopia, hypermetropia, astigmatism and/or presbyopia) of routine, it is unusual also will to measure and correct unconventional refractive power, as the scrambling of aberration, irregular astigmatism and/or the cataracta layer of eyes.In this inventive embodiments, except the refractive power of routine is unusual, also by the scrambling of aberration, irregular astigmatism and/or the cataracta layer of correction ocular, make patient's vision all rectifiable to better than 20/20 in most situation, as be remedied to 20/15, or better than 20/15, reach 20/10, and/or better than 20/10.

This useful unusual rectification is to utilize the electric excitation lens in these glasses to realize, these electric excitation lens are in fact as a kind of adaptive optical device.The adaptive optical device has obtained demonstration, and is used for correcting the atmosphere distortion of ground based astronomy telescope for many years always, and the atmospheric Laser Transmission of passing through that is used for correcting communication and military use.Under these situations, use sectional minute surface (segmented mirror) or " rubber " mirror (" rubber " mirror) to come the wavefront or the laser light wave of this image are carried out little rectification usually.Under most situation, these reflecting mirrors are all operated by mechanical driving device.

When the adaptive optical device is used for vision, it is based on and utilizes light beam, as the laser harmless to eye, eye system is carried out active probe and the wavefront distortion of having measured the image that produces on amphiblestroid reflection or the retina.The wavefront analysis of this form has been supposed a plane or sphere probing wave, and measures the distortion that is produced on this wavefront by eye system.By before the primary wave relatively with distortion after wavefront, it is unusual that the inspection personnel who is skilled in technique just can determine what to have in this eye system, and leave suitable corrective prescription.For the wavefront analysis device, have several competitive designs, but the present invention comprises also with electric excitation lens as described herein as transmission or reflective spatial light modulator, to carry out this wavefront analysis.The example of some wavefront analysis devices is provided in following two pieces of United States Patent (USP)s: United States Patent (USP) the 5th, 777, No. 719 (Williams) and the 5th, 949, No. 521 (Williams) is incorporated herein by reference all at these two pieces.

But, in certain embodiments of the present invention, a little little rectifications and adjustment have been done for these electric excitation lens, so that driving the grids of pixels array, electricity produces image light waves, the refractive index of this array is changeable, just can make the acceleration by light by these grids or slows down by this changeable refractive index.In this way, these electric excitation lens just become a kind of adaptive optical device, and it can compensate some intrinsic space defectives of the optics aspect of eyes self, so that obtain almost aberrationless image on this retina.

In some inventive embodiments, because these electric excitation lens are two-dimentional fully, so proofread and correct the fixed space aberration that optical system produced that just can compensate by these eyes by on total vision correction prescription demand of patient/user, introducing little refractive index.Like this, vision just can be remedied to and be better than the level that can reach with common focusing and adaptability house of correction, and under most situation, can reach than 20/20 better vision.

In order to reach than 20/20 better vision correction, can come the aberration of patient's eye is measured by for example a kind of improved automatic dioptric apparatus, this dioptric apparatus adopts a kind of Wavefront sensor or analyser of measuring ocular aberrations and designing that aim at.In case it is unusual to have measured unconventional refractive power of the aberration of these eyes and other type on amplitude and space, just can programme and introduce the variations in refractive index relevant, so that it is unusual to compensate the unconventional refractive power of these aberrations and other type except whole myopia, hypermetropia, presbyopia and/or astigmatism correction with two-dimensional space to the controller in these glasses.Like this, this embodiment of electric excitation lens of the present invention just can electric excitation corrects the aberration of patient's eye system or by aberration that this lenses produced.

Like this, for example,, in a certain electric excitation divergent lens, may need a certain-3.50 dioptric focal powers to correct in order to correct wearer's myopia.In this case, with different voltage V ₁... V _NArray be applied on M the element in this grid array to produce different refractive index N ₁... .N _MArray, this makes these electric excitation lens have-3.50 dioptric focal powers.But some element in this grid array needs their refractive index N ₁... .N _MVariation reaches ± 0.50 unit, so that aberration and/or unconventional refractive power of eyes are corrected unusually.Except the basic voltage of this myopia correction, also will be applied on the suitable grid elements with the corresponding small voltage deviation of above-mentioned variation.

In order to detect, to quantize and/or to correct unconventional refractive power as much as possible unusual, refractive power scrambling as irregular astigmatism, eyes, the scrambling of water content before or after the tear layer of facies anterior cornea, cornea for example, or the transparent inhomogeneities before or after the crystalline lens or other aberration that itself causes by this eyes dioptric system, can use this electric excitation dioptric apparatus/phoropter according to the embodiment of prescription method of the present invention 600 shown in Figure 6.

In step 610, no matter be conventional dioptric apparatus, electric excitation dioptric apparatus with routine and electric excitation lens, still only have the electric excitation dioptric apparatus of electric excitation lens or automatically dioptric apparatus can be used for measuring patient's refractive power unusual, when needing, also can use the focal power of conventional lenses, as the focal power of negative power (for myope), positive light coke (for the hyperope), cylindrical lens and the orientation (for the astigmat) of axle, and prismatical focal power etc.Utilize this method, the patient will recognize that unusually what is considered to patient's BVA (optimum visual resolution capability) at present by the rectification refractive power of routine.But some embodiment of the present invention but can bring up to patient's vision and exceed the level that present conventional dioptric apparatus/phoropter can reach.

Therefore, step 610 is the patient with a kind of unconventional invention means prescription provides further improvement.In step 610, will realize that described purpose prescription is programmed in this electric excitation dioptric apparatus.Suitable this patient of location, so as by these electric excitation lens with many grids electric excitation structure to improving and observing in the automatic dioptric apparatus of compatibility or the wavefront analysis device mutually, it is unusual so just can to measure this refractive power automatically and accurately.The unusual measuring method of this refractive power detects as much as possible and quantitatively to go out unconventional refractive power unusual.This measurement is to be undertaken by a zone that aims at the mark very little, that be approximately 4.29mm of each electric excitation lens, when calculating simultaneously required prescription automatically and watching by the target area of these electric excitation lens, go up at the alveole (fovea) of retinal centre along the direction of sight line and to obtain best focusing with this patient of box lunch.In case finish this measurement, this unconventional rectification just is stored in the memorizer of this controller/programmer so that use in the future, perhaps it is programmed in the controller of these electric excitation lens of control.Certainly, this process is multiple for two eyes.

In step 620, patient or wearer can select control unit for use by their suggestion now, the refractive power that this control unit can make them further improve routine is corrected unusually, unconventional refractive power is corrected unusually or both combinations, thereby improve last prescription, till making them satisfied.Selectively, or in addition, ophthalmologist oculist also can improve this rectification, till can not improving again.At this moment, the BVA after for this patient, will obtaining to improve, it is obtainable better by routine techniques institute than any.

In step 630, the prescription with any further improvement is programmed in this controller subsequently, and this controller is being controlled the prescription of these electric excitation lens.In step 640, prepare electric excitation glasses by programming.

Though aforesaid step 610 to 640 has been introduced a kind of embodiment of the inventive method, but judgement or method according to ophthalmologist oculist, can use a lot of differences but similarly method come vision to the patient to detect, quantitatively and/or correct, and in this process, use only be electric excitation dioptric apparatus/phoropter or with the combination of wavefront analysis instrument.The vision to people of coming any use electric excitation dioptric apparatus/phoropter detects, quantitatively and/or corrigent method, no matter order is how, whether, all be considered to a part of the present invention with the combination of wavefront analysis instrument.For example, in some inventive embodiments, step 610 to 640 just can with a kind of improved mode or even a kind of different order finish.In addition, among the embodiment of other inventive method, the diameter in the zone that aims at the mark of the lens of being mentioned in the step 610 is to arrive in the scope of about 8.0mm at about 3.0mm at some.And in other some inventive embodiments, this diameter that aims at the mark the zone anywhere all is the area from about 2.0mm to whole lens.

Though this discussion up to now is to concentrate on only to use various forms of electric excitation lens or carry out optometry so that finish on the problem of checking the future of eyes with the combination of its wavefront analysis instrument always, but have another kind of probability, promptly a kind of new technique may appear, objective measurement can be provided simply, the needs of replying or talking with like this, have just been eliminated potentially with exchanging of patient.Described herein and many inventive embodiments that ask for protection all wish to utilize the measuring system of any type to carry out work, no matter be objective, subjective, or not only objective but also subjective measuring system all could.

Getting back to these electric excitation lens now itself comes up, as mentioned above, one embodiment of the present of invention relate to a kind of electric excitation dioptric apparatus/phoropter with novel electric excitation lens, and this dioptric apparatus/phoropter can be that hybrid architecture also can be the structure of non-mixed.Hybrid architecture is meant the conventional haplopia (single vision) or the combination in multi-focus lens eyeglass and at least one electric excitation district, this electric excitation district is positioned on the front surface, on the rear surface and/or between front and rear surfaces, this district comprises a kind of electro-active material, thereby this material changes focus with the electric excitation mode of necessity by electronically.In certain embodiments of the present invention, this electric excitation district be placed in the lens particularly or the concave back face of these lens on so that make it avoid scratching and other common wearing and tearing.In the embodiment that comprises as the electric excitation district of part convex front face, all be coated with the anti-scratch coating under most situations.The multi-focus lens of conventional haplopia lens or routine and the combination in this electric excitation district just produce total lens strength of this hybrid lens scheme.Non-mixed structure is meant a kind of lens of electric excitation, so 100% only being produced by its electric excitation characteristic usually of its refractive power.

Fig. 7 is the front view of the embodiment of exemplary mixed type electric excitation eyeglass lens 700, and Fig. 8 is the sectional view along the intercepting of A-A line.In this legend, lens 700 comprise lenses 710.Attached on the lenses 710 being electric excitation refractive power matrix 720, it can have one or more electric excitation zones that occupy all or part of electric excitation refractive power matrix 720.Equally attached to being frame layers 730 on the lenses 710 and at least in part round electric excitation refractive power matrix 720.Lenses 710 comprises astigmatic focal power corrected zone 740, and this zone has astigmatism axle A-A, and only in this specific embodiment, this angle that clockwise rotates from horizontal direction is about 45 °.What cover electric excitation refractive power matrix 720 and frame layer 730 is optional cover layer 750.

As will further discussing, electric excitation refractive power matrix 720 can comprise liquid crystal and/or polymer gel.Electric excitation refractive power matrix 720 can also comprise alignment, metal level, conductive layer and/or insulating barrier.

In an alternative embodiment, removed astigmatism correction district 740, thereby lenses 710 is only corrected to spherical optical power.In another alternative embodiment, lenses 710 can be corrected unusually to the conventional refractive power of distance vision, near vision and/or both and any type, and is unusual comprising refractive power sphere, cylinder, prismatical and/or aspheric.Electric excitation refractive power matrix 720 also can be corrected near vision and/or unconventional refractive power unusual (as aberration).In other embodiments, the routine of electric excitation refractive power matrix 720 rectifiable any types or unconventional refractive power unusual, lenses 710 then can be corrected unusually to the refractive power of routine.

Find that the electric excitation lens with mixed structure have some tangible advantage compared with the electric excitation lens of non-mixed structure.These advantages are: circuit, the conductor that lower electrical power requirements, less battery size, battery life expectancy are long, not too complicated is less, insulator is less, manufacturing cost is lower, optical transmittance increases and structural integrity strengthens.But must be pointed out that non-mixed electric excitation lens also have it self some advantages, comprising thin thickness and can produce in batches.

Also find, when for example used electric excitation structural design was a kind of multi-grid electric excitation structure, the non-mixed and the whole audience in certain embodiments (full field) mixed type and a part mixed method all allowed producing by batch very much of the SKU of limited quantity (stock keeping unit).In this case, when making in batch,, only need emphasis mainly is placed on limited several distinguishing characteristics, as curvature and size for the physiological structure with the wearer adapts.

In order to understand this improved importance, people must be appreciated that the quantity that satisfies the needed conventional lenses blank of most of prescription.About 95% corrective prescription all comprises the spherical optical power rectification in-6.00 to+6.00 diopter scopes, and its dioptric recruitment is 0.25.According to this scope, nearly 49 kinds of spherical optical power of stipulating usually.Comprise the prescription of astigmatism correction for those, about 95% all in-4.00 to+4.00 diopter scope, and its dioptric increment is 0.25.According to this scope, nearly 33 kinds of astigmatism (or cylinder) focal powers of stipulating usually.Yet, because astigmatism has a last component, so, have the orientation of the astigmatism axle of about 360 degree if typically stipulate 1 ° increment.360 kinds of different astigmatism axle prescriptions like this, have just been arranged.

In addition, in order to correct the presbyopia, many prescriptions all comprise the bifocus parts.Correct presbyopic prescription for those, about 95% all in+1.00 to+3.00 diopter scope, and its dioptric increment is 0.25, obtains about 9 kinds of presbyopia's focal powers of regulation usually thus.

Because some embodiments of the present invention can provide sphere, cylinder, axial and presbyopic rectification, therefore a kind of non-mixed electric excitation lens can provide 5,239,080 (=49 * 33 * 360 *-9) to plant different prescriptions.Like this, a kind of non-mixed electric excitation lens just can not need the SKU of manufacturing in batches and/or a lot of lens blanks of stock, and may what is more important can not need by concrete patient's prescription every lens blank to be ground and polishes.

Need consider the problem of various lens curvatures with adaptation physiology, as the shape of face, eyelash length etc., can produce in batches and/or the stock than the non-mixed electric excitation lens that SKU is more slightly.Yet the number of SKU but can be reduced to about 5 or still less from millions of.

In the situation of mixed type electric excitation lens, find unusually and use most middle layers of electro-active by the conventional refractive power of correcting lens eyeglass, also can reduce required SKU number.With reference to figure 7, lens 700 can rotate on demand, so that astigmatism axle A-A is placed on the position that needs.The number of like this, required hybrid lens blank just can reduce with 360 multiple.In addition, the electric excitation district of this hybrid lens also can provide the presbyopia to correct, and reduces required lens blank number of packages order with 9 multiple again thus.Like this, the embodiment of mixed type electric excitation lens just can make required lens blank number of packages order reduce to 1619 (=49 * 33) from more than 500 ten thousand.Owing to can reasonably make in batches like this and/or the mixed type lens blank SKU of this number of stock, just do not need to grind and polished.

However, still possibly semi-finished product mixed type lens blank is ground and is polished to the finished lens blank.Figure 28 is the perspective view of the embodiment of semi-finished product lens blank 2800.In this embodiment, semi-finished product lens blank 2800 has lenses 2810, and this lenses 2810 has the surface 2820 that processed and unprocessed surperficial 2830, and the electric excitation refractive power matrix 2840 of part.In another embodiment, semi-finished product lens blank 2800 can have whole audience layers of electro-active.In addition, this electric excitation structure of semi-finished product lens blank 2800 can be multi-grid or single interconnection.In addition, semi-finished product lens blank 2800 also can have refraction and/or diffraction characteristic.

In the mixed type or non-mixed embodiment of these electric excitation lens, can be by can controlled device regulating and these electric excitation lens of control produce and a large amount of required corrective prescription of customization, and this controller customizes according to patient's concrete prescription demand and/or has programmed.Thus, just no longer need millions of prescriptions and many lens type, haplopia lens blanks, and many many focuses semi-finished product lens blank.In fact, the most lenses as far as our knowledge goes and the manufacturing of mirror holder and distribution all will thoroughly be changed.

Should be noted that, the present invention includes non-mixed electric excitation lens, and the specific blend type electric excitation lens situation of the whole audience and part field, the latter is electronic glasses of making in advance (mirror holder and/or lens) or the electronic glasses that customizes when giving patient or client.At these glasses is in the situation of making in advance and assembling, and mirror holder and lens all are ready-made in advance, and these lens are edging and putting in this spectacle-frame.This controller able to programme and re-programmable, and having the mirror holder of necessary electronic element and the batch process of lens also can be thought a part of the present invention, ophthalmologist oculist place or some other places can be made and deliver to this electronic component in advance so that the parts of Programmable Logic Controller for example and/or one or more controllers are installed by patient's prescription.

In some cases, controller and/or one or more controller part can be the parts of this mirror holder made in advance and electric excitation lens subassembly, and subsequently at ophthalmologist oculist place or some other places be programmed.This controller and/or one or more controller part can be the forms of chip or thin film for example, and can be put in the mirror holder, are contained on the mirror holder, put in the eyeglass of glasses or be contained on the eyeglass of glasses.According to the management tactics that will carry out, this controller and/or one or more controller part can be re-programmable or not be reprogramming.At this controller and/or one or more controller part is in the re-programmable situation, will allow patient's prescription is upgraded repeatedly, till patient or client are satisfied with to the function of his or her spectacle frame and decorative appearance and these electric excitation lens.

In a kind of situation in back, in the embodiment situation of this non-mixed promptly just discussed and mixed type electric excitation lens, these lens structurally must very firm safety, is enough to protect eyes not to be subjected to the injury of foreign body.In the U.S., most eyeglass all must be by the desired bump test of FDA.In order to satisfy these requirements, it is very important setting up supporting construction on this eyeglass inside or eyeglass.In the situation of mixed type, for example, this is that the haplopia of prescription or OTC (over-the-counter) or multi-focus lens eyeglass are finished as architecture basics.For example, the architecture basics of this mixed type can be made by Merlon.In non-mixed lens situation, in certain embodiments, selected electro-active material and thickness are all considered the needs of this structure.In other some embodiment, settle the carrier basis or the substrate of this OTC (over-the-counter) thereon also to consider this required protection electro-active material.

When using the electric excitation district in the eyeglass lens at some mixed structure, importantly, when power interruptions appears in these lens, still can keep the rectification of correct distance.When power supply or electric wire break down, in some cases, if the wearer driving a car or driving an airplane and lost they apart from the rectification ability, this may be catastrophic.For fear of the appearance of this situation, when this electric excitation district is in the OFF state (do not encourage or do not have electricity condition), electric excitation eyeglass lens design of the present invention can keep providing distance to correct.In an embodiment of the present invention, this can provide this to realize apart from rectification by the eyeglass that utilizes conventional fixed focal length, and no matter it is that refraction mixed type or diffraction mixed type can.Thereby the focal power of any extra increase is all provided by this electric excitation district.Thus, trouble-proof electric excitation system just occurred, this is because conventional lenses will keep this wearer's distance rectification.

Fig. 9 is the side view of the exemplary embodiment of another kind of electric excitation lens 900, and it has lenses 910, and this eyeglass has the refractive index that is complementary with electric excitation refractive power matrix 920.In this illustrated embodiment, this divergent lens eyeglass 910 has refractive index n ₁, it can provide distance to correct.Attached to being the electric excitation refractive power matrix 920 that can have unactivated state and many state of activation on the lenses 910.When electric excitation refractive power matrix 920 is that it has the refractive index n with lenses 910 when being in its unactivated state ₁The refractive index n of approximate match ₂More precisely, when un-activation, n ₂At n ₁0.05 refractive index unit within.What center on electric excitation refractive power matrix 920 is frame layer 930, and it has refractive index n ₃, its also with the refractive index n of lenses 910 ₁Approximate match, and at n ₁0.05 refractive index unit within.

Figure 10 is the perspective view of the exemplary embodiment of another kind of electric excitation lens combination 1000.In this illustrated embodiment, electric excitation lens 1010 comprise lenses 1040 and electric excitation refractive power matrix 1050.The emitter 1020 of diastimeter is placed on the electric excitation refractive power matrix 1050.And the detector/receptor 1030 of diastimeter also is placed on the electric excitation refractive power matrix 1050.In an alternative embodiment, emitter 1020 or receptor 1030 all can be placed in the electric excitation refractive power matrix 1050.In other alternate embodiments, emitter 1020 or receptor 1030 all can be placed within the lenses 1040 or on.In other embodiments, emitter 1020 or receptor 1030 all can be placed on the outer cover 1060.In addition, in other embodiments, 1020 and 1030 can also be placed in aforesaid any combination.

Figure 11 is the side view of an exemplary embodiment of diffraction electric excitation lens 1100.In this illustrated embodiment, lenses 1110 provides distance to correct.Etched on a surface of lenses 1110 is diffraction pattern 1120, has refractive index n .sub.1.Attached to lenses 1110 and to cover on the diffraction pattern 1120 be electric excitation refractive power matrix 1130, it has refractive index n .sub.2, and n.sub.2 is similar to n.sub.1 when electric excitation refractive power matrix 1130 is in its unactivated state.Equally attached on the lenses 1110 being frame layer 1140, it is by constituting with lenses 1110 identical materials basically, and to small part around electric excitation refractive power matrix 1120.Cover layer 1150 is attached on electric excitation refractive power matrix 1130 and the frame layer 1140.This frame layer 1140 also can be the extension of lenses 1110, wherein can add actual layer, yet lenses 1110 but is made into and can lives or restriction electric excitation refractive power matrix 1130 by frame.

Figure 12 is the front view of the exemplary embodiment of electric excitation lens 1200, and Figure 13 is its side view, and these lens have attached to the many focus lenses 1210 on the electric excitation frame layer 1220.In this illustrated embodiment, many focus lenses 1210 have the progressive lens arrangement that increases progressively.In addition, in this illustrated embodiment, many focus lenses 1210 comprise the 1212 and second progressive optics refractive power focal zone 1214 that increases progressively, the first optics refractive power focal zone.Attached on many focus lenses 1210 being electric excitation frame layer 1220, this floor has the electric excitation district 1222 that is placed on the second optics refractive power focal zone 1214.Cover layer 1230 is attached on the electric excitation frame layer 1220.Be noted that this frame layer can be electric excitation or non-electric excitation.When this frame layer is electric excitation, just use insulant to make this active region and the insulation of this non-activated areas.

In most rather than all invention situations, for the electric excitation glasses are programmed so that with patient's vision correction to best, will correct unusually unconventional refractive power, just the sight line that must follow the tracks of every eyes by the motion of following the tracks of patient or wearer's eyes.

Figure 14 is the perspective view of the exemplary embodiment of tracking system 1400.Mirror holder 1410 comprises electric excitation lens 1420.Attached to electric excitation lens 1420 back sides (this face the is the most close person's that joins the mirror eyes are also referred to as nearest side) be tracking signal source 1430, as light emitting diode.Equally attached to electric excitation lens 1420 back sides be tracking signal receptor 1440, as optical reflective sensor.Receptor 1440 and possible signal source 1430 all link to each other with the controller (not shown), and this controller comprises the instruction that tracking can be carried out in its memorizer.Utilize this method just eyes can be made progress, downwards, to the right, motion left, and any variation of eye motion is very accurately located.When needs are corrected some type but the unconventional refractive power of not all type is unusual, and these unconventional refractive powers need be restricted in patient's the sight line unusually the time (for example, inhomogeneous or have under the situation of projection for special cornea, inhomogeneous or the projection of this cornea will be along with moving when eyes move), just need like this.

In different alternative embodiment, signal source 1430 and/or receptor 1440 all can be attached to the back sides of mirror holder 1410, be embedded in the back side of mirror holder 1410 and/or be embedded in the back side of lens 1420.

The pith of any eyeglass lens comprises this electric excitation eyeglass lens, all is the part that is used for producing distinct image quality in user's the visual field.Although the people of a health can see the object in about 90 ° of its both sides, visual discrimination still is confined in the very little visual field the most clearly, and this visual field is corresponding to the retina part with optimum visual resolving power.Amphiblestroid this zone is called retinal centre nest (fovea), and it is approximately border circular areas, and the diameter of measuring on retina is 0.40mm.In addition, to the scene imaging, so the diameter of this pupil also will influence the size of the most critical part of this eyeglass lens to these eyes by whole pupil diameter.The key area of resulting eyeglass lens says to be exactly the diameter of glasses pupil and the summation of this projection of central fossa visual field on this eyeglass lens simply.

The typical range of this eye pupil diameter is 3.0 to 5.5mm, and the most common value is 4.0mm.Average central fossa diameter approximately is 0.4mm.

The typical range of the projection size of this central fossa on eyeglass lens is subjected to the influence of following parameter, as the length of these eyes, the distance that these eyes arrive this eyeglass lens etc.

Therefore, the tracking system of this special inventive embodiments just can will move this relevant zone location with eyes with respect to patient's retinal centre nest is regional on these electric excitation lens.When software of the present invention is programmed, thereby correct all the time when rectifiable unconventional refractive power is unusual when eyes move, this is very important.Like this, at great majority but in the not every inventive embodiments, must correct unusually, so that change the zone of these lens that this sight line passes through in its target of eye gaze or when staring with the method for electric excitation to unconventional refractive power.In other words, in described special inventive embodiments, most electric excitation lens are all corrected unusually to the refractive power of routine, and when eyes move, the focus in this scopodromic electric excitation zone also is moved by tracking system and software, so that this unconventional refractive power is corrected unusually, at this moment should consider angle that the different piece of this sight line and these lens intersects and it is counted in the ultimum praescriptus of this special area as the influence factor.

At great majority but in the not every inventive embodiments, when watching or stare at a distance target, use this tracking system and start software with patient's vision correction to its optimum state.When watching nearby, if use tracking system, then this tracking system is used to calculate the scope of focal length nearby, so that nearly scope of people or required regulating power and the convergence of middle zone focusing are corrected.Certainly, this is that a part as patient or wearer prescription is programmed in the controller of these electric excitation glasses, and/or in one or more controller part.Equally, in other inventive embodiments, also diastimeter and/or tracking system are incorporated in these lens and/or the mirror holder.

Should be noted that, in other inventive embodiments, for example those carry out in the corrigent inventive embodiments unconventional refractive powers of some type unusual (as irregular astigmatism), at great majority but in non-all situations, these electric excitation lens do not need to follow the tracks of the patient or join the mirror person's eyes.In this case, correct unusually, whole electric excitation lens are programmed for other conventional refractive power of and patient unusual to this unconventional refractive power.

Equally, because aberration is directly related with sighting distance, therefore has been found that and to correct this aberration with respect to sighting distance.That is to say, in case measured certain aberration or some aberrations, just can correct intravital these aberrations of this electric excitation refractive power base so that to specific range, as distance vision, far away-as middlely to carry out electric excitation apart from vision, near-middle aberration and correct apart from vision and/or near vision by this electric excitation zone is separated.For example, these electric excitation lens can be separated into distance vision, far away-middle apart from vision, near-middle rectification district apart from vision, near vision, each district of each software control makes this district to correct those aberrations that have influence on corresponding sighting distance.Thereby, in this concrete inventive embodiments, separate this electric excitation refractive power matrix by different distances, thus, the zone of each separation can be corrected the particular aberration of specific range, thereby just can under the situation of follower unconventional refractive power be corrected unusually not having.

At last, be noted that in another inventive embodiments, also can be under the situation of physical separation do not carried out in this electric excitation zone and not following the tracks of, realize such as the unusual rectification of this unconventional refractive power by aberration produced.In this embodiment, when utilizing sighting distance as when input, this software will regulate the focus in given electric excitation zone, realizing the required rectification to aberration, otherwise this aberration will have influence on the vision of this given sighting distance.

In addition, find that also mixed type or non-mixed electric excitation lens all can be designed to have the effect of the whole audience or part field.Whole audience effect is meant that this electric excitation refractive power matrix or layers of electro-active have covered the most lens area in the spectacle-frame.Under the situation of the whole audience, whole electric excitation zone all can be adjusted to the focal power that needs.And the electric excitation lens that can also regulate the whole audience are to provide the part field.Yet the concrete lens arrangement of the electric excitation of part field but can not be adjusted to the whole audience, and this is because the circuit that will make it become particular portion another arena needs causes.Whole audience lens adjustment is being become in the situation of part field lens, the subregion of these electric excitation lens can be adjusted to the focal power that needs.

Figure 15 is the perspective view of the exemplary embodiment of another electric excitation lens combination 1500.Mirror holder 1510 comprises the electric excitation lens 1520 with part field 1530.

In order to compare, Figure 16 is the perspective view of the exemplary embodiment of another electric excitation lens combination 1600.In this illustrated embodiment, picture frame 1610 includes the electric excitation lens 1620 with whole audience 1630.

In some inventive embodiments, these many focal lengths electric excitation lens are made in advance, and in some cases, owing to significantly reduced required SKU number, this many focal lengths electric excitation lens or even be used as many focal lengths of finished product electric excitation lens blank and the stock is joining the mirror place.This inventive embodiments allows to join the mirror place simply to many focal lengths electric excitation lens blank edging of this stock and fit in this electric start mirror holder.Though in most cases, the present invention can have the part field electric excitation lens of particular type, should understand that these electric excitation lens for the whole audience are effective too.

In a mixed type embodiment of the present invention, use conventional haplopia lenses that required distance optical power is provided, wherein said conventional haplopia lenses has aspheric surface or is not non-spherical structure, and this structure has the toroid and the sphere of the astigmatism of being used for.Astigmatism just should be selected the haplopia lenses of suitable focal power and it should be rotated to astigmatic appropriate position if desired.In case done like this, this haplopia lenses just can be carried out edging by the wire frame type and the size of these eyes.Then this electric excitation refractive power matrix is applied on this haplopia lenses, or before edging, just can applies this electric excitation refractive power matrix, and subsequently whole lens unit is carried out edging.Be noted that for before the edging with regard to this electric excitation refractive power matrix attached to the edging process on the lenses, no matter haplopia still is many focal lengths electric excitation lens, may be more superior such as the electro-active material of polymer gel than liquid crystal material.

Can this electric excitation refractive power matrix be applied on the compatible mutually lenses by different process more as known in the art.From the aspect of welding, aesthstic and/or appropriate final lens focal power, Jian Rong lenses is clinodactyly and the surperficial eyeglass that can both appropriately accept this electric excitation refractive power matrix mutually.For example, can use binding agent, this binding agent is applied directly on this lenses, lay this layers of electro-active then.In addition, also can make this electric excitation refractive power matrix like this, be about to it attached on the stripping film, in this case, it can take off to lay equal stress on and newly stick on this lenses.And it also can be attached on the two-side film membrane carrier, and this thin-film carrier itself sticks on this lenses.In addition, also can use surperficial foundry engieering to apply this stripping film, in this case, this electric excitation refractive power matrix is to go up in position to form.

In aforesaid mixed type embodiment, as shown in figure 12, use the combination of the method for static and non-static state to satisfy patient's the mid point and the needs of near point vision, many focal lengths progressive lens 1210 has the distance rectification of appropriate needs and has for example+1.00 dioptric full low coverage increases focal power, and this many focal lengths progressive lens is used to replace the haplopia lenses.When utilizing this embodiment, this electric excitation refractive power matrix 1220 can be placed on any side of this many focal lengths progressive lens eyeglass, also can be embedded in this lenses.This electric excitation refractive power matrix is used to provide additional increase focal power.

The increase focal power of in lenses, using than whole many focal length lenses required hour, be exactly total low many focal lengths that final increase focal power is generated by layers of electro-active increase the additional optical focal power of focal powers and other required low coverage focal power.Only lifting an example illustrates; If the increase focal power that many focal lengths progressive additive lenses eyeglass has is+1.00, and the low coverage focal power that electric excitation refractive power matrix produces be+1.00, and total low coverage focal power that then should mixing electric excitation lens just will be+2.00D.Utilize this method, can reduce undesired visual distortion significantly from many focal length lenses, particularly progressive additive lenses.

Use among the mixed type electric excitation embodiment of many focal lengths progressive additive lenses at some, this electric excitation refractive power matrix is used for removing undesirable astigmatism.This is to be realized by following method: only compensate by the counteracting focal power that electric excitation produced in having undesired scattered-light lens area and make undesired astigmatism offset or reduce significantly.

In some inventive embodiments, need to make the misalignment geometric center of this part field.When applying the electric excitation refractive power matrix of off-centered part field, needing that this electric excitation refractive power matrix is adjusted the suitable axis of astigmatism that adapts to this haplopia lenses by this way puts, so that can correct patient's astigmatism, if exist, also this electronic variable focal power field should be positioned on the appropriate location of patient's eye.In addition, for the design of part field, need to adjust the position of this part field, so that provide suitable off-centered position according to the needs of patient's pupil.Also find, in conventional lenses, static bi-focal, many focal lengths or gradation zone always are arranged on and do not reach the place that requirement is stared in people's distant surveillance, different with the lens of this routine, the use of electric excitation lens provides certain manufacturing degree of freedom, and this degree of freedom is not that conventional multifocal lens can provide.Therefore, in some inventive embodiments, this electric excitation zone is arranged on the place that people typically find long distance, middle distance and the near vision district of conventional non-electric excitation multifocal lens.For example, this electric excitation zone can be set at more than the 180 degree meridians of this lenses, and therefore the near vision district of many focal lengths just can be provided more than 180 degree meridians of this lenses sometimes.For those wearers in the position work very near apart from the target of its front or its above-head, as before the display of computer, working, or boat nail has the people of picture frame on head, and it is useful especially that the near vision district is provided more than 180 meridians of this lenses.

At non-mixed electric excitation lens, or in the situation of the mixed type part field lens of mixed type whole audience lens and for example 35mm diameter, press mirror holder lens fixed shape to the lens edging before, as previously mentioned, just can directly this layers of electro-active be added on this haplopia lenses, or be added in the blank that utilizes the formation electric excitation finished product multifocal lens that lenses makes in advance, or on many focal lengths progressive lens eyeglass.This permission is carried out pre-assembled to electric excitation lens blank, also can with finished product but not the electric excitation lens blank stock of edging get up, just can be thus and immediately prepare glasses at any channel of distribution and get ready, these channels comprise doctor or optician's office.This will make all mirror places of joining that service fast can both be provided, and also the demand to the manufacturing equipment of costliness can be reduced to minimum simultaneously.This is to manufacturer, the retailer, and their patient, client are beneficial to.

Consider the size of this part field, for example shown in the inventive embodiments, the specific region of this part field can be the middle or off-centered circular design of 35mm diameter.The size that is noted that this diameter can change as required.In some inventive embodiments, also used the circle diameter of 22mm, 28mm, 30mm and 36mm.

The size of this part field depends on this electric excitation refractive power matrix and/or electric excitation field structure.Have at least two kinds of such structures to be considered to belong to the scope of the invention, just single interconnection electric excitation structure and multi-grid electric excitation structure.

Figure 17 has the singly perspective view of the embodiment of the electric excitation lens 1700 of interconnection electric excitation structure.Lens 1700 comprise lenses 1710 and electric excitation refractive power matrix 1720.Insulator 1730 in electric excitation refractive power matrix 1720 is separated the activated part field 1740 and non-activation (or a zone) 1750 of belfry.Single line or conductive strips interconnection 1760 should activate the field and be connected on power supply and/or the controller.Note, at great majority but among the not every embodiment, the single line interconnection structure has independent a pair of electric conductor, and this structure is connected on the power supply.

Figure 18 is the perspective view of embodiment with electric excitation lens 1800 of multi-grid structure.Lens 1800 comprise lenses 1810 and electric excitation refractive power matrix 1820.In electric excitation refractive power matrix 1820, insulator 1830 is separated the activated part field 1840 and non-activation (or a zone) 1850 of belfry.A plurality of interconnection lines 1860 should activate the field and be connected on power supply and/or the controller.

When the part field of using than minor diameter, find, when using single interconnection electric excitation structure, just this layers of electro-active difference in thickness from the edge of the specific region of this part field to the center can be reduced to minimum.This has positive effect for will and reducing to minimum to the demand of the number of layers of electro-active to the demand of power supply, and is particularly all the more so for this list interconnection structure.For the specific region of the part field of using multi-grid electric excitation structure not always not like this.When using list interconnection electric excitation structure, in many but not every inventive embodiments, a plurality of single interconnection electric excitation structures are in these lens or all be lamellated on the lens, so that allow a plurality of layers of electro-active for example to produce+total combined electrical exciting light focal power of 2.50D.Only in embodiments of the present invention, just single interconnection layer of 5+0.50D can be stacked each other, with insulating barrier they are separated in most cases.By this way, reduce to minimum, make the variations in refractive index that suitable electrical power can be required to each layer generation, in some cases, always can not carry out appropriate excitation single interconnection layer of this thickness by electric demand with a thick single interconnection layer.

Be also pointed out that in the present invention some embodiment with a plurality of single interconnection layers of electro-active can activate by the sequence of programming in advance, so that the patient can be focused on the certain distance scope.For example, can activate single interconnection layers of electro-active of two+0.50D, the medium focusing of generation+1.00D, so that+presbyopia of 2.00D can see thing clearly on very near distance, then can with two other+single interconnection layers of electro-active of 0.50D activate so that+presbyopia of 2.00D can closely read on 16 inches distance.Should be understood that the accurate number of layers of electro-active, and every layer focal power can change according to concrete presbyopic specific myopia of optical design and covering and the needed total focal power of middle apparent distance scope.

In addition, in other the inventive embodiments, the combination of one or more single interconnection layers of electro-active combines with multi-grid layers of electro-active structure and is present in these lens at some.Moreover, suppose and can suitably programme, this just make the patient can the centering distance and close range focus on.At last, in other inventive embodiments, only multi-grid electric excitation structure is used in mixing or the non-hybrid lens.Which kind of situation no matter, this multi-grid electric excitation structure that combines with electric excitation eyewear controller and/or one or more controller part of suitably programming can be provided at the ability that very wide middle distance and close range focus on.

And, can carry out surface-treated semi-finished product cell excitation lens blank and also belong to scope of the present invention.In this case, no matter be off-center, middle part field electric excitation refractive power matrix, or whole audience electric excitation refractive power matrix all will combine with this blank, carry out surface treatment then to satisfy the needs of prescription.

In certain embodiments, the electric excitation scope of this variable optical strength is positioned on the whole lens, and regulates the needs that near vision focuses on when working to adapt to people by constant spherical optical power variation on the whole surface of these lens.In other embodiments, this variable optical power range can change by constant spherical optical power regulates on whole lens, meanwhile also produces aspheric peripheral focal power effect, so that reduce distortion and aberration.In some above-mentioned embodiment, remote focal power is to come corrigent by the finished lens blank of haplopia, many focal lengths or many focal lengths progressive lens eyeglass.This electric excitation optical layers mainly is need correct for the focusing of operating distance.Be noted that thing is not always like this.In some cases, can only use haplopia, many focal lengths finished lens eyeglass or many focal lengths progressive lens eyeglass to obtain the spherical optical power of long distance, and correct near vision work focal power and astigmatism by electric excitation refractive power matrix, perhaps only use haplopia or many focal length lenses eyeglass to come astigmatism, and correct spherical optical power and near vision work focal power by this layers of electro-active.And, also can utilize plane, haplopia, many focal lengths finished lens eyeglass or gradual-change multi-focus apart from lenses, and correct long distance sphere and astigmatism by this layers of electro-active.

Should be noted that, by the present invention, required focal power is corrected, and no matter is prismatical, sphere or aspheric focal power, and the assembly of the additional optical focal power that the focal power demand of total distance optical power demand, middle distance and focal power demand nearby all can be by arbitrary numbers is realized.This comprises use haplopia or many focal length lenses of finished product eyeglass, when this haplopia or many focal length lenses of finished product eyeglass combine with layers of electro-active, just can satisfy: the needs of the needs of all long distance spherical optical power, the needs of some long distance spherical optical power, all astigmatic focal powers, the needs of some astigmatic focal powers, the needs of all prismatic focal powers, the needs of some prismatic focal powers or the combination of above-mentioned any needs, this will satisfy focusing needs that people are total.

Find that this electric excitation refractive power matrix allows to use the corrigent technology of similar adaptive optics, so that before or after in the end making, just can be by the electric excitation lens of he (she) with its eyesight optimumization.This can realize by following method: allow the patient or have a mind to that the wearer watches by these electric excitation lens or a plurality of electric excitation lens and manual adjustments they, perhaps realize by the automatic dioptric apparatus of particular design, this dioptric apparatus almost just can measure conventional at once and/or unconventional refractive power unusual, and can correct unusually refractive powers such as the spherical aberration of any remainder, astigmatism, aberrations.Under many situations, this technology can both make the wearer obtain 20/10 or better vision.

In addition, should also be noted that in certain embodiments that Fresnel focal power lens jacket uses with this haplopia or many focal lengths or many focal length lenses blank or eyeglass and this layers of electro-active.For example: be used to provide spherical optical power with this Fresnel layer, and reduce the thickness of lens thus, this haplopia lenses is used for astigmatism, this electric excitation refractive power matrix then is used for correcting the needs of middle distance and in-plant focusing.

As mentioned above, in another embodiment, the diffraction eyeglass uses with this haplopia lenses and this layers of electro-active.In this method, the extra corrigent diffraction eyeglass of focusing is provided, also reduced demand to power supply, circuit and layers of electro-active thickness.Moreover, can also use the combination of following any two or more parts to provide patient's glasses to correct the required total additional optical focal power of focal power in additional mode.These parts are Fresnel layer, routine or unconventional haplopia or many focal length lenses eyeglass, diffactive lens lamella and electric excitation refractive power matrix or multilamellar.In addition, also can give this electro-active material, have the non-mixed of diffractive part or Fresnel component or the electric excitation lens of mixed type so that produce with the shape and/or the effect of diffracting layer or Fresnel layer by engraving method.And, use these electric excitation lens not only can produce conventional lens strength, but also can produce prismatical focal power.

Also find, use diameter to be approximately the certain electric excitation lens design of the circular middle mixed type part field of 22mm or 35mm, or when using diameter to be approximately the particular design of the off-centered mixed type electric excitation part of scalable of 30mm, thereby just demand, battery life, the battery size of power circuit can be reduced to the optical transparence that minimum has reduced manufacturing cost and improved final electric excitation eyeglass lens.

In an inventive embodiments, become to make this optical center to be positioned on the position of about 5mm below this haplopia optical center of lens the certain electric of this eccentric part another arena excitation lens position, the electric excitation part that also makes nearly operating distance simultaneously is to nasal bone or to temple off-centre so that satisfying this patient corrects closely-neutralizes closely-in to far-interpupillary distance during middle operating distance scope.Should be noted that this method for designing is not limited to circular design, in fact can be the Any shape that can satisfy the suitable electric excitation visual range area of having of patient's vision needs.For example, this design can be oval-shaped, orthogonal, foursquare, octagonal, the part bending, or the like.Particular design for mixed type part maybe can realize the mixed type whole audience design of part field, and the non-mixed whole audience design that can realize the part field equally, importantly to the appropriate setting of its field range.

In one exemplary embodiment, shown in Figure 53 a, this electric excitation district is can be in vertical direction eccentric, makes when the patient wears these glasses, and pupil 5310 is positioned at 5320 tops, near vision district or near 5320 tops, near vision district.The advantage of the lens of this configuration is only to require slight eyes or head to move by this and distinguishes 5330 object observings, this district 5330 can provide closely-in or far away-middle apart from vision correction or this two kinds of vision corrections.The patient also can use near vision to read under the mobile situation that do not need or need slightly to direct one's eyes downward.

In another exemplary embodiment, shown in Figure 53 b, this electric excitation district can be eccentric in the horizontal direction.In this embodiment, near vision district 5320 and middle apart from optic zone 5330 (can be near-in or far away-in) to nasal bone direction off-centre, when seeing shown in observed patient's right eye in the face of this patient.Off-centre to the nasal bone direction can allow to read the nature of the eyes that occur in the work process to internal rotation.In this embodiment, be approximately 2mm,, and can change according to the patient although this distance only is exemplary obviously to the off-centre of nasal bone direction.

In another exemplary embodiment in eccentric electric excitation district, shown in Figure 53 c, this

electric excitation district

5320 and 5330 can be eccentric on vertical direction and horizontal direction.This exemplary embodiment can not have to provide under remarkable or any mobile situation closely-far away-middle use apart from vision that neutralizes at head or eyes, reads the nature of eyes in the work process to internal rotation and solved simultaneously.

Figure 53 d shows another exemplary embodiment.This embodiment has shown makes

electric excitation district

5320 and 5330 off-centre, pupil 5310 placed outside 5320 borders, near vision district and to distinguish within 5330.When the object observed before just in time being positioned at pupil, when for example watching computer monitor, under situation about moving without any head or eyes, this embodiment provide for closely-in or far away-middle use apart from vision.Utilize the patient of the lens of this embodiment to use the near vision district that is used to read by slightly moving of eyes or head.

Should be appreciated that these embodiment obviously only are exemplary, and can change according to for example patient's custom or observation needs.Having generated this electric excitation district easily all falls within the scope of the present invention with respect to other position and these positions of this patient's pupil.Equally, this electric excitation district can eccentric independently different amount.Closely-neutralization is far away-middle in work process, the low coverage district can also be closed fully, so pupil is more not strict about middle position apart from vision, this be because the whole zone in

district

5330 and 5320 only can have closely-in or far-middle apart from focal power.Yet, have available near vision and near-middle simultaneously apart from vision or far away-middle in the embodiment of vision in hope, need conscientiously select the position of pupil in the electric excitation district according to previously described factor, thereby make the optimized performance of these glasses.

Have been found that in many (but not every) situation, used electric excitation refractive power matrix with non-uniform thickness.In other words, this metal with conduction around layer and nonparallel, and the thickness of gelatin polymer also changes, so that the lens shape that can form convergence or disperse.Can non-mixed embodiment have haplopia or the mixed type embodiment of many focal length lenses eyeglass in use the electric excitation refractive power matrix of such non-uniform thickness.Various combinations fixed by these and the lens can electricity regulated present multiple adjustable lens focal power.In some inventive embodiments, this list interconnection electric excitation refractive power matrix has used uneven uneven gauge that produces this electric excitation structure.But most but in the not every inventive embodiments, this multi-grid electric excitation structure has but been used parallel construction, this structure has formed the uniform thickness of this electric excitation structure.

For some probabilities are described, can be bonded on the convergence electric excitation lens, assembling the haplopia lenses so that form the mixed type lens subassembly.According to used electric excitation lens material, this voltage can make refractive index increase or reduce.As about shown in first row of the table 1 of the lens strength various combination of fixed and electric excitation like that, produce not too big positive light coke thereby voltage is heightened the focal power that can change final lens subassembly in order to reduce refractive index.The refractive index of this electric excitation lenses is increased, and then the focal power of this final mixed type lens subassembly will change, such as about shown in the table 2 of the lens strength various combination of fixed and electric excitation.Should be noted that in this embodiment of the present invention, be only required in and apply single voltage difference on this layers of electro-active.

The feasible manufacture process of this mixed type assembly is as follows.In one embodiment, the polymer gel layer of this electric excitation can injected mold, casting, impression, machined, diamond turning and/or is polished to pure lenses shape.By for example sputter or vacuum deposition this thin metal layer is deposited on the two sides of polymer gel layer of this jet mould or casting.In another exemplary embodiment, the thin metal layer of this deposit not only be placed on the lenses but also be placed on jet mould or the another side of the electro-active material layer of casting on.Conductive layer not necessarily, if but this conductive layer is necessary, it is equally also by vacuum deposition or be splashed on this metal level.

With the bi-focal of routine, many focal lengths or progressive lens difference, in these lens, the near optical power part needs different location for different many focal length designs, and the present invention can always place on the common position.Different with the different static light focal powers district that conventional method is used, in this conventional method, in order to utilize one or more such districts, needing eyes to move with head verts, the present invention allows the patient directly to see forward or slightly up or down, and the part of this whole electric excitation or the whole audience just can be regulated so that be remedied to required nearly operating distance.The fatigue of eyes and the motion of head and eyes have so just been reduced.In addition, when needs of patients was seen at a distance, this adjustable electric excitation refractive power matrix just can be regulated so that correct in order knowing and to see the focal power that distant objects is required.Under most of situations, can make the nearly operating distance of this electric excitation scalable field become flat focal power like this, so just these mixed type electric excitation lens being changed or regulate back is distance vision correcting lens or many focal lengths of the low power progressive lens that is used to correct distance optical power.But it is not always such.

In some cases, the thickness that reduces the haplopia lenses may be useful.For example, can compensate the central thickness that reduces plus lens or the edge thickness of minus lens by in this electric excitation tunable layer, carrying out some suitable distance optical power.This is applicable to the whole audience or most whole audience mixed type electric excitation eyeglass lens, or the situation of all non-mixed electric excitation eyeglass lens.

Moreover, should be noted that, this scalable electric excitation refractive power matrix might not be positioned in the limited zone but can cover whole haplopia or many focal length lenses eyeglass, no matter the shape or the area of desired haplopia or many focal length lenses eyeglass are what kind of all should be like this.Only be because performance and attractive in appearance is just limited accurate overall dimension, shape and the position of this electric excitation refractive power matrix.

Find that also the suitable lordosis by utilizing haplopia or many focal length lenses blank or eyeglass and the curved surface of recurve can further reduce the complexity of electronic circuit required for the present invention, this also is a part of the present invention.The base curve of the lordosis by this haplopia of suitable selection or many focal length lenses blank or eyeglass can reduce to minimum by the needed connection electrode number of this layers of electro-active of excitation.In certain embodiments, when with the whole electric excitation scope of the power adjustment of one group of quantity zone, only need two electrodes.

This is that it can produce the forward and backward or intermediary layers of electro-active of different focal powers according to the placement location of this layers of electro-active because the change of refractive of this electro-active material is caused.Therefore, the suitable curvature relationship of every layer forward and backward curved surface can influence this electric excitation mixing or the needed focal power adjusting of non-mixed lens.Great majority but in non-all situations, hybrid design, particularly those do not use in the hybrid design of diffraction or Fresnel component, importantly this electric excitation refractive power matrix does not have the forward and backward curved surface that parallels with the curved surface of this haplopia or many focal lengths semi-finished product blank or haplopia or many focal lengths finished product blank, and above-mentioned layers of electro-active is attached on this blank.An exception of this situation just is to use the hybrid design of multi-grid structure.

Be noted that a kind of embodiment with mixed type electric excitation lens has used the method for the too late whole audience and two minimum electrodes.Other embodiment then uses the method for multi-grid electric excitation refractive power matrix to form electric excitation refractive power matrix, needs a plurality of electrodes and circuit in this situation.When using multi-grid electric excitation structure, will find the grid border that on decorating, can accept (cannot see mostly) for those by electric excitation, between adjacent cells, need to produce the refractivity of a 0-0.02 refractive index unit.According to the requirement on decorating, the scope of this refractive index difference can from 0.01 to 0.05 refractive index unit, but in most inventive embodiments, is being the difference limit between the adjacent area to the maximum 0.02 or 0.03 refractive index unit by controller.

Also can use one or more different electric excitation structures that have,,, produce the final additional optical focal power that needs in case its activation just can be worked on demand as the layers of electro-active of single interconnection structure and/or multi-grid structure.Take a single example, the patient can correct the distance optical power of the whole audience and utilize (promptly near from eye) electric excitation refractive power matrix of back by (away from the layers of electro-active of wearer's eyes) of front, comes the near vision zone focusing of the part field ad hoc approach that produces for the layer that utilizes by the back.When these layers maintenance being approached in the extreme and reduced complexity of each single layer, utilize this many electric excitations refractive power matrix method just can improve its motility, this point should be clearly.In addition, this method can also be got up single layer ordering so that the patient can all activate them at one time to produce simultaneously variable additional optical focal power effect.This variable focusing effect can produce by the order that the time passes, and from when closely watching, the focusing demand of the energy centering apparent distance and near-sighted distance is corrected, and then produces a contrary effect when people watch from the near to the remote with convenient patient.

The method of this many electric excitations refractive power matrix also can provide the response time of electric excitation focal power faster.This is because the combination of some factors produces, and factor is the thickness that has reduced the required electro-active material of each layer in many layers of electro-active lens.And also because many electric excitations matrix allows the main electric excitation refractive power matrix of complexity is resolved into two or more not too complicated monolayers, the thing that these monolayers are required respectively to do compares that main layers of electro-active is desired will be lacked.

Come below the material of these electric excitation lens and structure and electrical harnesses circuit thereof, power supply, electric switch technology, the required software of focus adjustment, and object distance mensuration etc. makes a presentation.

Figure 19 is the perspective view of the exemplary embodiment of electric excitation refractive power matrix 1900.Attached to the both sides of electro-active material 1910 are metal levels 1920.Attached to the opposite side of each metal level 1920 are conductive layers 1930.

Above-mentioned electric excitation refractive power matrix is the multi-ply construction that is made of polymer gel or liquid crystal as electro-active material.Yet, in some invention example, in same lens, used polymer gel and two kinds of electric excitation refractive powers of liquid crystal matrix.For example, liquid crystal layer can be used to produce the effect of electronics tone or sunglasses, and this polymer gel layer then can be used to increase or reduce focal power.Polymer gel and liquid crystal both have following characteristic, and promptly light refractive index can change along with the voltage that is applied.This electro-active material is covered by two almost transparent metal levels on its each side, and on each metal level deposit conductive layer so that provide good electrical connection for these layers.When on these two conductive layers, applying voltage, between it, just produced electric field, thereby this refractive index is changed by this electro-active material.In most cases, with liquid crystal, and be with gel in some cases, being loaded in the big envelope of sealing, the material of this big envelope is by select making from materials such as silicon, polymethacrylates, styrene, proline, pottery, glass, nylon, mylar.

Figure 20 is the perspective view of embodiment with electric excitation lens 2000 of multi-grid structure.Lens 2000 comprise a kind of electro-active material 2010, and this material defines a lot of pixels in certain embodiments, and each pixel can be separated by the material with electrical insulation characteristics.Like this, electro-active material 2010 just can limit a lot of adjacent districts, and each district includes one or more pixels.

Attached to a side of electro-active material 2010 be metal level 2020, it has the grid matrix by the separated metal electrode 2030 of material (not shown) with electrical insulation characteristics.Attached to the opposite side (not shown) of electro-active material 2010 are symmetric same metal layer 2020.Like this, each electric excitation pixel and pair of electrodes 2030 be complementary right to limit grating element.

Attached to being conductive layer 2040 on the metal level 2020, on this conductive layer, have a plurality of interconnection vias 2050, every interconnection vias all uses the material (not shown) with electrical insulation characteristics to separate.Every interconnection vias 2050 pair is electrically connected a grid elements with power supply and/or controller.In another embodiment, some and/or all interconnection vias 2050 can pair couple together not only grid elements with power supply and/or controller.

Should be noted that in certain embodiments, saved metal level 2020.In some other embodiment, replaced metal level 2020 with alignment.

In some inventive embodiments, (far away) surface, intermediate surface and/or rear surface all are to be made by the material that comprises conventional autochromy composition before this.This autochromy composition can with or can be not with the tone characteristics of relevant electron production a part as these electric excitation lens.If use it, then it will provide additional tone in the mode of compensation.Yet, be noted that in many inventive embodiments this photochromatic material only is used to not have the electric excitation lens of electronics tonal content.The constituent that this color photographic material can be used as this layer is included in the electric excitation lens jacket, or in adding electric excitation refractive power matrix afterwards to, or add to as an outer field part on the front or back of these lens.In addition, be coated with dura mater before or after the electric excitation lens of the present invention, also can all apply anti-reflective film on demand on forward and backward two sides.

This structure is called sub-component, and can automatically controlledly produce prismatic focal power to the wearer, spherical optical power, the rectification of astigmatic focal power, aspheric rectification to it, or the rectification of aberration.In addition, this sub-component of may command effect of imitating Fresnel or Difraction surface.In one embodiment, the two or more sub-components that separated by electric insulation layer then can and be put in not only one type rectification if desired.This insulating barrier can be made of silicon oxide.In another embodiment, same sub-component is used to produce the rectification of multiple focal power.The all available two kinds of different structures of the embodiment of two sub-components just having described are made.The embodiment of this first kind of structure allows each above-mentioned layer, and layers of electro-active, conductive layer and metal level all are back to back, and in other words, these material layers are successive, have formed single interconnection structure thus.The embodiment of second kind of structure (as shown in figure 20) has used some metal levels of grid or array format, electric insulation between the subarray district that each subarray district all is adjacent.In this embodiment, show multi-grid electric excitation structure, this conductive layer of etching is so that electrically contact or electrode for each subarray or grid elements provide isolating.Like this, just independent and different voltage can be applied in this layer each, thereby in this electro-active material layer, produce the zone of different refractivity on the grid elements.The details of design comprises the curvature etc. of arrangement, each layer or parts of number, layer or parts of structure, layer or parts of thickness, refractive index, voltage, the candidate's of layer electro-active material, layer, all leaves optical design teacher for and goes to determine.

Be noted that many grids electric excitation structure or single interconnection electric excitation structure can both be used as part lens field or whole lens field.But, when using the certain electric excitation refractive power matrix of part field, in most cases, then use a kind of electro-active material with refractive index of tight coupling to serve as the certain electric excitation of part field and the material of dead layer (frame layer), this layer laterally opened in abutting connection with the certain electric active region of this part field and by the specific electric excitation region separation in insulator and this part field.Doing like this is for when being in unenergized condition, looks like an integral body by the outward appearance that keeps whole electric excitation refractive power matrix, improves the ornamental of these electric excitation lens.In addition, should also be noted that in certain embodiments that this frame layer is made of non-electro-active material.

This polymeric material can be a polymer miscellaneous, and the electric excitation component in these polymer is 30% by weight at least.Such electric excitation polymeric material is well-known and all can have bought on market.The embodiment of this material comprises liquid crystal polymer, as polyester, polyethers, polyamide, Polychlorinated biphenyls (PCB) (penta cyano biphenyl) or the like.Polymer gel also can comprise the processability that a kind of thermosetting matrix material improves gel, improves it and the adhesive force that encapsulates conductive layer, and the optical clarity that improves gel.Only illustrate for some examples, this substrate can be crosslinked acrylate, methacrylate, polyurethane, with crosslinked polyvinyl (vinyl polymer) of difunctional or multi-functional acrylate, methacrylate or poly derivant etc.

For example the thickness of this gel layer can be between about 3 microns to about 100 microns, but also can thickly reach 1 millimeter, and perhaps, as another embodiment, its thickness can be between about 4 microns to about 20 microns.For example, this gel layer can have about 100 pounds/inch and arrive about 800 pounds/inch coefficient, and perhaps as another embodiment, this coefficient is about 200 to 600 pounds/inch.The thickness that this metal level can have is for example about 10 ^-4Micron is to about 10 ^-2Micron, and as another embodiment, also can be from about 0.8 * 10 ^-3Micron is to about 1.2 * 10 ^-3Micron.The thickness that this conductive layer can have for for example 0.05 micron to about 0.2 micron order of magnitude, and as another embodiment, also but from about 0.8 micron to about 0.12 micron, and as another embodiment, can be about 0.1 micron.

This metal level is used to form excellent contact between conductive layer and electro-active material.Those skilled in the art will identify spendable proper metal material easily.For example, people can use gold or silver to make this metal level.

In one embodiment, the refractive index of this electro-active material can change between for example about 1.2 units and about 1.9 units, and as another embodiment, also can between about 1.45 units and about 1.75 units, change, and change of refractive is at least 0.02 unit/volt.Refractive index will determine this percentage composition of electric excitation polymer in this host material with the actual refractive index of the rate of change of voltage, this electro-active material and with the compatible mutually of this host material, and be approximately 2.5 volts but when being not more than 25 volts, the variations in refractive index that then can cause final composition is for being not less than 0.02 unit/volt at basic voltage.

As discussed earlier, for the inventive embodiments of using hybrid design, the each several part of electric excitation refractive power matrix component all be with suitable adhesive or bonding technique attached on the lenses of routine, this binding agent or cementing layer all are transparent to visible light.The assembling of this gummed can be undertaken by peeling paper or stripping film, for this electric excitation refractive power matrix is glued on this conventional lenses eyeglass, in advance with this electric excitation refractive power matrix pre-assembled and attached on this paper or the film preparation.It can generate on the due position and be applied on the stand-by lenses surface.And, also it can be applied on the surface of lenticular sheet in advance, and then this lenticular sheet is adhesive on this stand-by lenses.It can also be applied on the semi-finished product lens blank, again this blank be carried out Surface Machining or edging subsequently to the needs that satisfy suitable size, shape and suitable total focal power.At last, can utilize surperficial casting technique that it is cast on the prefabricated lenses.This just produces focal power of can electricity regulating of the present invention.This electric excitation refractive power matrix can occupy whole lens area, also can only occupy its part.

The refractive index of this layers of electro-active only just can change exactly to the zone that needs focus on.For example, in an aforesaid mixed type part design, the zone of this part field is always in this regional underexcitation and change.Thereby in this embodiment, this refractive index only changes in the specific part zone of these lens.In the embodiment of another mixed type whole audience design, refractive index changes on whole surface.Equally, in this non-mixed design, this refractive index also changes on whole zone.As described earlier, have been found that in order to keep acceptable visual decorative appearance that the refractive index difference between the adjacent area of electric excitation lens should be restricted to a maximum 0.02-0.05 refractive index unit, is preferably 0.02-0.03 unit.

Can imagine that within the scope of the invention the user can use the part field in some cases, want then this electric excitation refractive power matrix is transformed into the whole audience.In this case, should come the Structured Design present embodiment according to the embodiment of the whole audience; Yet, tackle that this controller is programmed so that satisfy focal power is transformed into part field and the conversion demand of returning again from the whole audience, vice versa.

In order to produce the required electric field of these electric excitation lens of excitation, voltage is applied on this optical module.This is to be realized by the strand of some minor diameters, and these strands are included on the glasses edge.These leads are introduced the controller of these electric excitation glasses from following described power supply, and/or in one or more controller parts, and guide on the edge around each eyeglass lens, here, use existing wire-bonded technology used in the quasiconductor manufacturing that these leads are connected on each grid elements in this optical module.In the embodiment of single conductor interconnection structure, i.e. lead of each conductive layer, each only needs a voltage with the mirror lens, and only needs two leads for each lens.Voltage is applied on the conductive layer, and the pairing conductive layer on the opposite face of this gel layer maintains on the earthing potential.In another embodiment, will exchange (AC) voltage is applied on the relative conductive layer.Be easy to finish near these two edge places that are connected each eyeglass lens or its.

If use grid array voltage, then each the grid subregion in this array all comes addressing with different voltage, and some electric conductors will be introduced every lead in the framework and be connected on the grid elements on these lens.Optically transparent conductive material, as Indium sesquioxide., stannum oxide, or tin indium oxide (ITO) all can be used to form the conductive layer of this electric excitation assembly is connected to the lead on the edge on each grid elements in the electric excitation lens being used for.No matter this electric excitation zone has occupied whole lens area, still only occupy the part of lens area, this method all is feasible.

One of technology that is used for realizing pixelation in the multi-grid array design is to make one small-sized volumetrical electro-active material, and each has its oneself paired drive electrode so that set up electric field on this small-sized volume materials.Another technology that realizes pixelation is to use patterned electrodes in conduction or metal level, and this electrode photoetching is formed on the substrate.By this method, this electro-active material can be included in the successive volume, and the different electric field regions that produce this pixelation are limited by the electrode of this patterning fully.

For power supply being provided for this optical module, in this design, comprise the power supply of battery and so on.The voltage that is used to produce this electric field is very little, and therefore, the lower limb of spectacle frame is designed to allow to insert and take out the structure of the minicell that this power supply is provided.By the multichannel connection that is included in equally in the mirror holder lower limb these batteries are connected on this strand.In another embodiment, utilize binding agent that some uniform hull cells are sticked on the surface of mirror holder lower limb, when battery electric quantity exhausts, can take off like this and replace them.Another selectable scheme provides the AC adapter, is connected on the battery that is fixed on the mirror holder, so that can not charge on the spot to this piece battery or consistent hull cell in time spent.

A kind of selectable power supply also may be included in the micro fuel cell in the eyeglasses frame, and the energy reserve bigger than battery is provided.With little fuel tank the bin that fuel injects spectacle frame just can be charged to this fuel cell.

Find that the method for the mixed type multi-grid structure of the application of the invention just can reduce to the demand to power supply minimum, most but be not that this structure comprises the specific region of part field in all situation.Can use the multi-grid structure of mixed type part field although be noted that people, also can use mixed type whole audience multi-grid structure.

Correct in the inventive method of unconventional refractive power unusual (as aberration) at another, as mentioned above, tracking system can be structured in these glasses, but and provide the appropriate function software that is installed in these electric excitation glasses and program control electric excitation eyewear controller and/or one or more controller part.This inventive embodiments is not only followed the tracks of people's sight by the eyes of following the tracks of people, but also required electric energy is imposed on the specific region of these electric excitation lens that sight line just passing through.In other words, corresponding with the people's sight of directly passing these electric excitation lens when eyes move, the electric excitation district that is aligned also can move on lens.This will obtain proof in multiple different lens design.For example, correct unusually for the refractive power to (sphere, cylinder and the prism) of routine, user may have the mixing of lens, electric excitation lens or two types of lens of fixed light focal power.In this example, this unconventional refractive power will obtain by the electric excitation refractive power matrix with multi-grid structure correcting unusually, and whereby, when eyes moved, the excitation area of corresponding electric excitation lens will move along with eyes.In other words, the sight line of eyes moves corresponding to these eyes, will move mobile on lens relatively with these eyes when sight line intersects with this lens.

In above-mentioned inventive embodiments, be noted that this multi-grid electric excitation structure that is introduced in these mixed type electric excitation lens or on these lens can have part field or whole audience design.

Be noted that people only just can reduce to the demand to electricity minimum by the finite region that the electric excitation sight line is directly passed through when using this inventive embodiments.Thereby for given prescription, the area that is energized at any time is more little, and then the electric energy of Xiao Haoing is just few more.Most but be not that the non-zone that observes directly can not be activated or encourage, thereby always to the ametropia of routine, for example myopia, hypermetropia, astigmatism, presbyopia correct, and make the patient reach 20/20 vision correction in all situation.In embodiments of the present invention, be aligned that always to correct unconventional refractive power as much as possible unusual with tracked zone, they are scramblings of irregular astigmatism, aberration and ocular surface or layer.In other inventive embodiments, be aligned or tracked zone also can correcting some routines unusually.In aforesaid several embodiment, described be aligned with tracked zone can be by controller and/or one or more controller part, and by being placed in the diastimeter (range finder) that these eyes of tracking move in these glasses, and be placed in eye tracking system in the glasses, perhaps locate automatically by tracking system and range-finding system.

Though in some design, only use part electric excitation zone, but with electro-active material with whole surface coverage, in lens, see annular line to avoid in being in nonexcited state user.In some inventive embodiments, the middle section that uses transparent insulator to make electric excitation be confined to just be energized, and use unperturbed peripheral electro-active material to make the edge of excitation area invisible.

In another embodiment, on the surface of thin-film solar cells group attached to mirror holder, and the photoelectric effect of utilizing sunlight and surround lighting to produce is applied to voltage on lead and the optical grating.In one embodiment, use solar battery group to make main power source, and comprise that aforesaid minicell makes stand-by power supply.When not needing power supply, during this period of time this battery just can be charged by solar cell in this embodiment.Another scheme also provides the AC adapter for this design and has been connected on these batteries.

For variable focal length is provided to user, these electric excitation lens are available on-off control.Two switching positions are provided at least, but then can provide more switching position if desired.In the simple embodiment, this electric excitation lens or open, or close.When on the position of closing, there is not electric current to flow through lead, do not have voltage to be applied on this grid assembly, and only used fixed lens strength.Always like this, for example, what suppose certainly that these mixed type electric excitation lens use is to be used to correct the haplopia of distance vision or many focal length lenses blank or the eyeglass part as its structure when the user needs long distance to correct.Read required near vision rectification in order to provide, switch can be to open, and provides predetermined voltage or array of voltages to lens thus, thereby produces positive increase focal power in this electric excitation assembly.Apart from vision correction, just can comprise the 3rd switching position if desired.This switching can be controlled by microprocessor, or is manually controlled by the user.In fact, can comprise a plurality of additional positions.In another embodiment, this switch is mimic and nonnumeric, and can provide the continually varying focal length of lens by adjusting knob or stick, and this resembles the volume control on the radio very much.

Can be this situation, do not have fixed lens strength in the parts of this structure, and whole vision correction be finished by these electric excitation lens all.In this embodiment, if the user needs long distance and near vision rectification, voltage or array of voltages are provided in all time, all can for so these lens.If the user regulates when only needing distance vision to correct or read, then these electric excitation lens will be opened when needs are corrected, and close in the time need not correcting.But, always not such.In certain embodiments, according to the design of lens, closing or reducing voltage automatically to increase long distance and or the focal power near vision district.

In one exemplary embodiment, this switch itself places on the mirror holder of this eyeglass lens and with controller and links to each other, and for example, is included in the special IC in this spectacle frame.Described controller is regulated the diverse location that responds this switch by the voltage that this power supply is supplied with.Thus, sort controller has just constituted above-mentioned multiplexer, and it connects lead with different voltage distribution to those.This controller also can be the advanced design with form of film, and installs along the surface of this mirror holder as battery or solaode.

In one exemplary embodiment, described controller and/or one or more controller part, can make and/or programme by the rectification requirement of known patient's vision, and the user is easily switched between different predetermined voltage arrays, and these voltage series are to customize according to his (she) individual visual needs.The controller of this electric excitation glasses and/or one or more controller part can be easily taken out by ophthalmologist oculist or technician and/or programme, and can come according to new " prescription " controller is replaced and/or reprogramming when user's vision correction demand change.

A scheme based on the switch of controller is that it can change the voltage that is applied on the electric excitation lens in less than the time of a microsecond.If this electric excitation refractive power matrix high-speed switch material, then the rapid transformation of this focal length of lens can destroy wearer's vision.Need to be converted to another focal length from a focal length lenitively.As additional feature of the present invention, " time-delay " program can be enrolled the transformation that slows down focal length in this controller.On the contrary, also " in advance " program can be enrolled the transformation of quickening this focal length in this controller.Equally, this transformation can be estimated by predictive algorithm.

In a word, can set the time constant of this transformation, make it and to regulate the needed variations in refractive index of wearer's vision proportional and/or in response to this variation.For example, the little variation of focal power can promptly be changed, and the big variation of focal power, when as the wearer its sight target from afar being moved on the printing material of reading rapidly, then can be set in the time cycle that occurs in than length, such as the 10-100 millisecond.This time constant is to regulate by glasses wearer's comfortable situation.

In a word, do not need with switch be placed on glasses originally on one's body.In another exemplary embodiment, this switch can be placed in the pocket of user's clothes and can manually encourage in a separate modules.This switch can link to each other with these glasses with thin wire or optical fiber.The switch of another kind of type comprises little microwave or radio frequency short-range transmitter, and it can be sent to the signal about the position of the switch on the fine reception antenna that as one man is arranged on the spectacle frame.In these two kinds of constructions of switch, the user can carry out controlling in the focal length variations scope of his (she) glasses directlyly and carefully.

In different exemplary embodiments, this switch is by ken detector, and for example range unit is controlled automatically, and this range unit is placed in the mirror holder of glasses for example, on the mirror holder, in the lens and/or on the lens, and points to the target that will observe forward.

Figure 21 is the perspective view of another inventive embodiments of electric excitation glasses 2100.In this illustrated embodiment, mirror holder 2110 comprises electric excitation lens 2120, and these electric excitation lens are connected on controller 2140 (integrated circuit) and the power supply 2150 by connecting lead 2130.The emitter 2160 of diastimeter is attached on the electric excitation lens 2120, and the receptor 2170 of diastimeter is attached on another electric excitation lens 2120.In various alternative embodiment, emitter 2160 and/or receptor 2170 can on mirror holder 2110, embed in the lens 2120, and/or embed in the mirror holder 2110 attached on arbitrary electric excitation lens 2120.And the emitter 2160 of range finder and/or receptor 2170 can be controlled by controller 2140 and/or isolating controller (not shown).Equally, the signal that is received by receptor 2170 can be handled by controller 2140 and/or isolating controller (not shown).

In a word, this range finder is a kind of active probe, and it can use various light sources: come localizing objects and measure the distance of this target as laser instrument, light emitting diode, rf wave, microwave or ultrasonic pulse.In one embodiment, Vcsel (VCSEL) is used as optical transmitting set.The small size of these devices and flat appearance make them have very big captivation for the application.In another embodiment, with the light source of Organic Light Emitting Diode (or OLED) as this diastimeter.It is transparent that the advantage of this device is that OLED can be made into mostly usually.Like this, perhaps be exactly the design of preferred diastimeter if consider ornamental OLED so, can be not in sight because it can be introduced in lens or the picture frame.

To be used to receive on one or more positions that proper sensors from the reflected signal of target is arranged on this lens mirror holder front and link to each other so that the computed range scope with small controller.In another embodiment, can make one device playing the dual function of emitter and detector, and be connected with this distance range computer.This distance range sends to by lead or optical fiber on the switch controller that places this lens mirror holder or on Digiplex on one's body, and it is analyzed so that the distance of this target is determined switch setting accurately.In some cases, distance range controller and switch controller can be integrated.

Should be appreciated that in some cases, when the wearer wants when the focus of an object moves on to the focus of another object, this range unit is difficult to switch the focal length of these electric excitation lens.For example, before these lens switched to another kind from a kind of vision correction, the emitter of this diastimeter and receptor need be come by the wearer of these lens extraly that moving-head could switch.In addition, when these lens when the actual required vision correction of wearer switches to inappropriate vision correction, can produce " mistake switching ".For example, when these lens switch to far-middle distance or near-middle distance or closely during vision correction from remote vision correction, rather than switch to the in fact needed remote rectification of wearer.

Therefore, in another exemplary embodiment, in order to control the transmitted beam width that produces by this emitter, and, supplementary lens can be covered on the emitter and receptor of this diastimeter selectively by the light acceptance cone that this receptor receives.

Figure 44 a is the decomposition section of integrated power supply, controller and diastimeter in accordance with another embodiment of the present invention.Shown in Figure 44 a, system 4400 comprises the range unit 4420 that is connected with controller 4440, and this controller is connected with power supply 4460 successively.Figure 44 b be according to an embodiment of the invention among Figure 44 a system 4400 along the side cross-sectional views of Z-Z ' direction.Shown in Figure 44 b, range unit 4420 comprises diastimeter emitter 4424 and diastimeter receptor 4428.In this exemplary embodiment, diastimeter emitter 4424 and diastimeter receptor 4428 are respectively emitting diode and reception diode, for example, can be the IR laser diodes, the form of LED or other non-visible radiating light source.In this exemplary embodiment, emitter 4424 has optionally covered diversing lens 4426 so that the transmitted beam width that control is produced by emitter 4424.Equally, receptor 4428 can optionally be coated with receiver lens 4430 so that the light acceptance cone that control is received by receptor 4428.Should be appreciated that the receiving area of receptor 4428 or light cone district comprise solid angle, exceed this solid angle, then in a single day pass receiver lens, aperture or other device that covers receptor 4428 and will arrive on the receptor 4428 near the light of this range unit.The protection window can shield the internal part of range unit 4420, and more specifically, maskable emitter and receptor make its influence of avoiding user surrounding environment, also can not have influence on the function of this internal part simultaneously.

Figure 45 is the side view of this diastimeter emitter 4424 among Figure 44 b according to an embodiment of the invention.As shown in figure 45, diversing lens 4426 has selected diverging light focal power, the light beam B that is produced by emitter 4424 can be dispersed to be the given pattern width D on the given operating distance L.Like this, the width of this light beam that is produced by emitter 4424 is best for being used to read the given operating distance of watching with middle distance, this width will minimize the demand that head additionally moves, simultaneously by undue increase of this light beam not avoided wrong switching.

Figure 46 is the side view of the diastimeter receptor 4428 of Figure 44 b according to an embodiment of the invention.As shown in figure 46, this receptor 4428 optionally is coated with receiver lens 4430, is formed with hole, slit 4432 in this receiver lens 4430.The receiver lens 4430 that use has hole, slit 4432 can be reduced to the rectangular area basically with the pattern that is received, rather than receiver lens 4430 detected whole visuals field when not being installed on the receptor 4428.In this embodiment, receiver lens 4430 is made of for example opaque material, can prevent that like this receptor 4428 from receiving any reflected light except that passing hole, slit 4432.

Should be appreciated that, above-mentioned have the diversing lens 4426 that covers emitter 4424 and the embodiment that covers the receiver lens 4430 of receptor 4428 only is exemplary, also can adopt the embodiment of the light acceptance cone of other emission light beam that uses emitter 4424 or receptor 4428 to reduce the wrong optical property of switching or improving optical system 4400 further.For example, other method of the reception pattern of restriction light acceptance cone or receptor comprises the hole, variable shutter, lens or the device that use other geometry and limits light transmission to receptor 4428.Be also to be understood that it is selectable that lens are placed on emitter and the receptor, can provide the combination in any of said lens according to the present invention.For example, in another embodiment at least, it is selectable being used for the receiver lens 4430 that selectivity covers receptor 4428.Equally, in another embodiment at least, it also is selectable being used for the diversing lens 4426 that selectivity covers emitter 4424.In above-mentioned exemplary inventive embodiments, needs that extra head is moved and wrong generation of switching all increase along with the width of the emission light beam that is produced by the diastimeter emitter and selectively handle folded light beam and how to appear on this diastimeter receptor and reduce to minimum.

In another exemplary embodiment, this switch can be little and move fast and control by user's head.This will be by another visual field detector in the lower limb that is included in this lens mirror holder, and for example minisize gyroscopes or miniature accelerometer are finished.Head small, rock or reverse and will trigger this minisize gyroscopes or miniature accelerometer fast, and make switch rotate some set positions of allowing, thereby the focus of these electric excitation lens changed on the rectification position of hope by it.For example, according to mobile detection by minisize gyroscopes or miniature accelerometer, can programme so that for range unit provides focal power to this controller, viewed like this zone can be subjected to this range unit inquiry so that need to determine whether the change of vision correction.Equally, after interval or time cycle, wherein do not detect head and move at the fixed time, then can close this range unit.In addition, at least one embodiment, after moving detection and using this range unit, then can also open this range unit.

In another exemplary embodiment, can use another kind of visual field detector, whether gradient switch for example, the head of determining this user be low or lift with the given angle of the posture that is higher or lower than someone sight direct-view distant place of expression.For example, a kind of exemplary gradient switch can comprise the mercoid switch that is arranged on the controller, and only when the patient looks up with distance horizontal line predetermined angular or looks down, this mercoid switch just can cut out the circuit that power supply is provided for diastimeter and/or controller.Because lens can be designed to not correct at a distance under the state of power supply having, in at least one embodiment, when user's head tilted downward or upward with distance horizontal line predetermined angular, this range unit can be configured to another kind of state (for example closely or middle distance correct) is handled and switched to these electric excitation lens from remote rectification.In addition, these lens can adopt additional demand, i.e. the sensed one period preset time cycle of target near or middle distance before switching beginning.This gradient switch also can be used to be provided with logic high, set with diastimeter then, the expression target is arranged in closely still the logic level of intermediate distance and passes through together and door (in positive logic).

Figure 47 a-47c is optical lens system wearer's a side view according to an embodiment of the invention.Shown in Figure 47 a, the wearer of optical lens system can be with his head from horizontal adjustment to head same upward-inclination angle degree (θ _Up), reach from horizontal adjustment to head downtilt angles (θ _Down).Figure 47 b represents that the wearer is with head downtilt angles (θ _Down) downward-sloping its head.Figure 47 c represents that the wearer is with the head angle (θ that is inclined upwardly _Up) its head is inclined upwardly.In one exemplary embodiment, when wearer's head moves up or down about 5 to 15 degree from horizontal level, and preferably move about 10 when spending, can close this gradient switch (and be this range unit or controller, or the two provides power supply) from horizontal level.In another embodiment, when wearer's head moves up or down about 15 to 30 degree from horizontal level, and preferably move about 20 when spending, can close this gradient switch from horizontal level.

Should be appreciated that the above-mentioned embodiment of gradient switch that adopted can be optimized according to wearer's hope and requirement.For example, this wearer can select and make that depart from from horizontal level, different on direction up or down for closing the required angle of switch.Like this, the angle that is inclined upwardly that is used to close switch can equate that with downward-sloping angle perhaps they also can differ the several years each other.In addition, when downward-sloping its head of wearer, perhaps selectively, only when the wearer is inclined upwardly its head, this gradient switch can also be optimized by only encouraging diastimeter (or be range unit or controller, perhaps the two provides power supply).Because everyone downward-sloping slightly head is read, so latter event is unlikely.

In another inventive embodiments, this system uses the gradient switch to determine the angle of inclination of wearer's head.No matter the angle of this inclination is that make progress or downward, can send to determine whether in the controller that whether this inclination is greater than predetermined angle.Therefore, this controller can come optionally to this diastimeter power supply according to the gradient of crossing the gradient threshold value relevant with this gradient switch.Equally, In yet another embodiment, can use minisize gyroscopes or micro accelerator in a similar fashion.For example, minisize gyroscopes or micro accelerator can produce output, and controller is according to the position of the definite wearer's head of this output, and corresponding adjustment is to the power supply of this range unit.

Another exemplary embodiment has been used the combination of minisize gyroscopes and hand switch.In this embodiment, this minisize gyroscopes is generally the following reading of 180 degree and visual performance uses, so that in response to the inclination of people's head.Therefore, when people's head inclination, this minisize gyroscopes just transmits a signal in the controller, and the gradient of this signal indication head subsequently according to the demand that tilts, is converted to this gradient the focal power of growth.For some or be higher than 180 the degree visual performances, under the situation of for example working before computer, remote-controlled hand switch is used to replace minisize gyroscopes.

In another embodiment, used the combination of diastimeter and minisize gyroscopes.Other visual performance that this minisize gyroscopes is used for myopia and is lower than 180 degree, and this diastimeter is used for above viewing distance and for example four inches or the viewing distance still less of 180 degree.In yet another embodiment, range unit can be used in combination with gradient switch, minisize gyroscopes or micro accelerator, determines whether to switch these electric excitation lens.In these embodiments, controller can be to each integrated component, and for example gradient switch, gyroscope or accelerator use logic level according to additional requirement, this requirements for example switch begin before this range unit must obtain new viewing distance.

As the possibility of hand switch or diastimeter design, another exemplary embodiment that is used to adjust electric excitation assembly focal power has been used the eye tracking instrument to measure the distance between the pupil and has been detected this viewing distance.When eyes focus at a distance or during nearby target, described distance will and be dispersed and changes along with the contraction of pupil.At least two light emitting diodes and at least two adjacent photoelectric sensors are arranged in the mirror holder near the bridge of the nose, and this photoelectric sensor is used to detect the light that sends from this diode of eye reflections.This system can detect the position at every eye pupil edge, and is distance between the pupil with this position transition, so that calculate this eyes of user plane range-to-go.In certain embodiments, three or four light emitting diodes and photoelectric sensor can be used to follow the tracks of moving of eyes even.

Should be appreciated that, In yet another embodiment, the combination of various devices described herein, can combine by any way as required with the wearer's that satisfies technical staff and this optical lens system needs, the combination of wherein said various devices can be decreased to excessive mobile of the switching of mistake and wearer initial switching.Like this, can the customized logic level or switching device in any one satisfy the real needs of given user.

Except vision correction, this electric excitation refractive power matrix can also be used to make eyeglass lens to produce a kind of electronics tone.Just can make lens produce the effect of tone or sunglasses by apply suitable voltage on suitable gelatin polymer or liquid crystal layer, this has changed the absorbance of light scioptics to a certain extent.This light intensity that has reduced just makes lens produce the effect of a kind of " sunglasses ", and the user felt comfortably cool in the outdoor environment of light.Have the liquid crystal composition of high polarization and gelatin polymer for this application very attractive for the electric field that is applied.

In some inventive embodiments, the present invention can be used on the position of variations in temperature even as big as the refractive index that influences this layers of electro-active.Then, must apply correction factor to all voltage of supplying with this grid assembly and compensate this influence.Be installed in lens and/or mirror holder the inside or above, and the variation that the miniature critesistor that is connected with power supply, thermoelectric occasionally other temperature sensor can detected temperatures.This controller is transformed into the required change in voltage of this electro-active material variations in refractive index of compensation with these readings.

Yet, in certain embodiments,, be actually and embed electronic circuit among the lens or place on the surface of lens in order to increase the temperature of this electric excitation refractive power matrix or layer.Do the refractive index that has further reduced these layers of electro-active like this, make the variation of lens strength reach maximum thus.When strengthening or not strengthening voltage, all can utilize increasing of temperature, so just can be in the extra motility of controlling and change generation aspect this lens strength by variations in refractive index.When serviceability temperature, preferably can measure, obtain to feed back and controlled to the temperature of having a mind to apply.

In the grid array in the electric excitation zone of the part or the independent addressing of the whole audience, may need many leads in the future the specific voltage of self-controller be multiplexed on each grid elements.In order to be easy to arrange these interconnection lines, the present invention is placed in the previous section of this eyeglasses frame with this controller, for example, and in bridge of the nose district.Like this, the power supply that is placed in the leg of spectacles only just can be connected with this controller with two leads by the mirror holder hinge of leg of spectacles front.Those leads that controller is connected on the lens can all be included in the previous section of this mirror holder.

In some embodiments of the invention, these glasses can have one or two eyeglasses frame lower limb, and its part is easy to disassemble.Every leg of spectacles all comprises two parts: keep the part of the weak point that partly is connected with this hinge and preceding mirror holder and insert this part the part of length.Each can pull up the part of coming from leg of spectacles all comprise power-supply battery (battery, fuel cell etc.), and disassembles and again with on it is connected from the standing part of this lower limb at an easy rate.These dismountable lower limbs are chargeable, for example, it are put into portable A.C. charger, and this charger is to charge with DC current, magnetic induction or any other general charging method.Like this, the replacement lower limb that charges electricity can be connected on these glasses, so that the excitation of continuous, long lens and range-measurement system to be provided.In fact, for this purpose the user can carry a plurality of replacement lower limbs in its pocket or parcel.

Under a lot of situations, the wearer need correct carrying out sphere apart from vision in far away, near and/or near or far away.This has just allowed totally interconnected grid array lens to change, and wherein this variation has utilized the symmetric advantage of the ball that requires corrigent eyeglass.In this situation, the grid of the special geometry that is made of the concentric ring in electric excitation zone can comprise subregion or whole audience lens.These rings can be circular or non-circular, as ellipse.This configuration can be used to reduce significantly required must be with the lead that the has different voltages number in the electric excitation zone of addressing respectively, thereby simplified this interconnection circuit widely.Thisly be designed to use the mixed type lens design to carry out astigmatism correction condition is provided.In this case, conventional eyeglass can provide cylinder and/or astigmatism correction, and the electric excitation refractive power matrix of concentric ring can provide the long distance of sphere and/or near vision to correct.

The embodiment of this concentric ring or annulus make electric excitation focus on to adapt to wearer's needs aspect very big motility is provided.Because therefore the symmetry of this annulus can prepare a lot of complexity that can not increase wiring and interconnection than thin districts.For example, the electric excitation lens that are made of 4000 grid pixels will need the circuit to this all 4000 district's addressing; Covering diameter is that the needs of 35 millimeters circular portion region area can produce about 0.5 millimeter pel spacing.On the other hand, the self adaptation eyeglass that is made of the concentric ring pattern of 0.5 millimeter same spacing (or ring thickness) will only need 35 annuluses, reduce the complexity of wiring thus widely.On the contrary, the spacing of this pixel (and resolution) can be reduced to only 0.1 millimeter, and the number that only will distinguish (and interconnection line) is increased to 175.Concerning the wearer, the bigger resolution in this district just can be transformed into bigger comfortableness, and this is because be more level and smooth and more demulcent from a radial variations of distinguishing the refractive index in another district.Certainly, this design is limited in people in essence just on the vision correction of sphere.

Find that also this concentric ring designs the thickness of customizable annular ring, so that the resolution of maximum is placed on the radial location that needs it.For example, if should design need bag phase (phase-wrapping), promptly when the periodic advantage of utilizing light wave to realize bigger focal power with the material with limited variations in refractive index, people can design a kind of array, the subregional periphery of rounded portions at the electric excitation area of this array has narrower ring, and has the ring of broad at this regional center.Use to this wisdom of each annular pixel can produce obtainable maximum focal power for used district's number, can will be present in mixing repeatedly effect and reduce to minimum in the low resolution system that uses the bag phase simultaneously.

In another embodiment of the present invention, in the mixed type lens that adopt part electric excitation district, need the rapid transition from the far field focal zone to the near vision focal zone is become level and smooth.This occurs on the circular boundary in this electric excitation zone certainly.In order to realize this point, the present invention will programme and make to have the less focal power that is used for myopia in the zone of this electric excitation area peripheral edge.For example, consider a kind of mixed type concentric ring design of electric excitation zone of the 35mm of having diameter, wherein the lens of fixed focal length provide the long distance rectification, and this electric excitation zone provides+and 2.50 additional optical focal power presbyopia corrects.Several annular regions or " band " are programmed so that have the focal power that reduces at bigger diameter place, rather than until this electric excitation area peripheral edge all keeps this focal power constant, each wherein above-mentioned annulus or " band " are all comprising several addressable electric excitation concentric annular district.For example, in the process of motivation, an embodiment can have: the circle of the 26mm diameter at center, its additional optical focal power is+2.50, and diameter expands to the endless belt of 29mm from 26mm, and its additional optical focal power is+2.00, another endless belt diameter expands to 32mm from 29mm, its additional optical focal power is+1.50, is surrounded with diameter on every side and expands to the endless belt of 35mm from 32mm, and its additional optical focal power is+1.0.This design is favourable in that comparatively comfortable wearing is provided for the certain user aspect experiencing.

When using the ophthalmology eyeglass lens, for distant surveillance, people generally use the only about half of of this lens top.Observe for middle distance, people generally use above approximately 2-3mm of center line and the following approximately part of 6-7mm of center line, and are used near viewing in the part of the following 7-10mm of center line.

The aberration that eyes produce is different for the distance from eyes, thereby need carry out different rectifications.The distance of the target of observing is directly related with required corrigent concrete aberration.Therefore, to need approximately uniform rectification for all remote by the aberration that optical system produced of eyes, for all far away-middle distances, will need approximately uniform rectification, for all near-middle distances, approximately uniform rectification will be needed, and for all anomalistic distances, also approximately uniform rectification will be needed.Therefore, the present invention's permission is carried out electric excitation to these lens and is regulated in three or four parts (at a distance partly, middle distance part and closely part) of these lens, so that correct this some aberration, this with when the sight line of these eyes and eyes is mobile on lens as possible a grid then grid ground these electric excitation lens of adjusting are opposite.

Figure 22 is the front view of the embodiment of electric excitation lens 2200.Having defined various zones in lens 2200 provides different refractive powers to correct.Below center line B-B, one middle distance corrected zone 2230 surrounds several closely corrected zone 2210 and 2220, each closely corrected zone all have different rectification focal powers.Although only show two closely corrected zone 2210 and 2220, can provide the closely corrected zone of arbitrary number.The middle distance corrected zone of arbitrary number equally, also can be provided.On center line B-B, provide remote corrected zone 2240.The zone 2210,2220 and 2230 can be encouraged by the order of having programmed so that saves energy for example, perhaps also can by with three focal lengths (tri-focal) of routine similarly the static switch mode encourage.When by as far as closely, or when watching from the near to the remote, lens 2200 can focus on by the eyes that the transitions smooth between each focal length that makes each zone be helped the wearer.Thus, just exempt or reduced widely the phenomenon of " image jump ".

Jump and discontinuity by the image that utilizes the electric excitation mixed zone can dwindle selectively between the vision correction district.Represented a kind of exemplary embodiment among Figure 54.Exemplary embodiment shown here has represented to place the electric excitation district in the fixed distance optical element 5340.Near vision district 5320 is blended in the district 5330 on the mixed zone 5420, and this district 5330 can provide closely-and middle apart from vision, far away-middle apart from correcting or these two.The electric excitation district that this mixed zone 5420 can be an any width, but it is wide or littler to be preferably about 6mm.When patient's sight line was left a vision correction district and moved to another vision correction district, this mixed zone 5420 can be covered or shields interborough discontinuity and reduce image and jump by providing to seamlessly transit.Another mixed zone 5430 can be between district 5330 and distance vision district 5340.Mixed zone 5430 can have width arbitrarily, but it is wide or narrower to be preferably 10mm.In any mixed zone, this mixed zone can be the linear hybrid of focal power reduction, or the mixing of being represented by multinomial or exponential function.Low coverage and near-in or far away-middle apart from focal power among the simultaneous embodiment, this mixed zone 5420 can carry out the transition to closely from the low coverage focal power-or far-middle apart from focal power.Do not having near-in or far away-middle under the situation in district among the embodiment in excitation near vision district, this mixed zone 5420 can provide the transition from the near vision focal power to the distance vision focal power.In most of embodiment, mixed zone 5430 can provide from closely-or far away-middle transition apart from focal power to distance optical power.

Though the pupil 5310 shown in Figure 54 is placed in the middle with respect to the electric excitation district, as other position is described herein, these lens can be placed to other different modes and place pupil with respect to the electric excitation district of these lens.

Return to discuss diffraction electric excitation lens now, be used to correct the unusual electric excitation lens of refractive power can use and the electric excitation refractive power matrix of glass, polymer or plastic substrate lens adjacency prepare, above-mentioned substrate lens are printed on or etching has diffraction pattern.This substrate lens surface with diffraction impression directly contacts with this electro-active material.Like this, a surface of this layers of electro-active also can have diffraction pattern, and this pattern is the mirror image of the lip-deep diffraction pattern of this substrates of lenses.

This assembly, typically is used for long distance and corrects so that these substrate lens always provide fixed rectification focal power as the mixed type lens.Almost the refractive index with these substrate lens is identical to be in the refractive index of this electric excitation refractive power matrix of unenergized condition; Its difference should be 0.05 refractive index unit or littler.When these electric excitation lens were unexcited, these substrate lens had identical refractive index with electric excitation refractive power matrix like this, and this diffraction pattern is inoperative, thereby rectification (0.00 diopter) is not provided.In this state, the substrate power of lens is unique rectification focal power.

When this electric excitation refractive power matrix is activated, its variations in refractive index, and the refractive power focal power of this diffraction pattern can be added on these substrate lens.For example, if the substrate lens have-3.50 dioptric focal powers, and it has+2.00 dioptric focal powers when the electric excitation diffracting layer is activated, total then the focal power of this electric excitation lens subassembly is exactly-1.50 diopters.Like this, but just near viewing or the reading of these electric excitation lens.In other embodiments, the refractive index that is in this electric excitation refractive power matrix of foment can be complementary with this lenses.

Be used to observe corrigent a plurality of district by utilizing lamination electric excitation zone, can utilizing simultaneously.Figure 55 has represented to have two electro-active vision correction districts 5520 and 5530 and the long distance exemplary embodiment of correcting the electric excitation lens in district 5540, and this long distance is corrected the district and can be provided by the optical element of fixed distance.These districts can represent one or more lamination electric excitations zone, and the observation rectification of wherein distinguishing in 5520 and 5530 is different, correct according to different observations and encourage the electric excitation zone, below will be described further.

In certain embodiments, can generate far-middle apart from the vision correction district.This far away-middle apart from correct the district can for for comfortable near-middlely corrected far apart from observing, provide enhanced observation rectification and correct too near object for significantly effective distance vision.Usually, these distances can be about 5 feet to about 15 feet.

Represented to have the exemplary embodiment of the electric excitation lens in lamination electric excitation zone among Figure 55 a.Lens 5500 have two electric excitation zones.Each zone can be corrected near vision half focal power is provided.Shown in Figure 55 a, the area in a zone can be less than another zone, yet these two zones also can have identical size.As these two zones of excitation and people during by these two regional observations, near vision can occur and correct, and if people during only by a regional observation, can occur near-middle apart from correcting.Alternatively,, for example encouraged zone 5565, and do not had excitation area 5560 iff one that has encouraged in two zones, then on whole electric excitation zone, occur near-middle apart from vision.

Represented to have the exemplary embodiment of far away-middle electric excitation lens apart from the vision correction district among Figure 55 b.Lens 5500 have among independent low coverage corrected zone 5560 and two apart from corrected zone 5565 and 5570, and All Ranges all is the electric excitation type, and can pile up each other.Low coverage corrected zone 5560 can be provided for providing 50% of additional optical focal power that the near viewing house of correction needs.Remaining can be apart from five equilibrium between corrected zone 5565 and 5570 in two.When one in the excitation area 5565 or 5570 only and when not encouraging low coverage zone 5560, can occur far away-middle apart from correcting.Can occur near-middle distance when not encouraging low coverage zone 5560 and excitation area 5565 and 5570 corrects.When excitation low coverage zone 5560 and middlely can occur near vision apart from the zone 5565 and 5570 the time and correct.

Optical element by fixed distance can provide long distance to correct district 5540, for example have+long distance of 4.0 dioptric focal powers corrects the patient that the district is used to have the hypermetropia situation.As described in other position herein, this can provide a kind of " automatic anti-fault " pattern, if make arbitrarily the electric excitation zone or all the electric excitation zones focal power loss or other problem appear, then the patient still can have the long distance observation ability.As another embodiment, this patient also may have the visual problems such as presbyopia, corrigent+2.5 dioptric focal powers that this needs to be used near vision respectively, be used near-apart from vision correction+1.25 dioptric focal powers and be used for far away-apart from vision correction+0.625 dioptric focal power.

In this embodiment, the total maximum focal power of this lens electric excitation part can be in order to correct near vision problem+2.5 diopters.For being provided, near viewing corrects, can encourage all electric excitation zones, thereby produce+6.5 dioptric total focal powers when object is observed in the district when correcting by low coverage, promptly by whole three electric excitation zones of having encouraged (be used to correct distance vision+4.0 diopters add be used to correct near vision+2.5 diopters) observe.Total focal power in electric excitation zone can be accumulated, if therefore this patient changes into and observes near-middle object in scope, then can be under the situation that does not have excitation area 5560 excitation area 5565 and 5570 independently, thereby provide+1.25 dioptric total focal powers growths perhaps+5.25 dioptric whole vision correction.Equally, if the patient observes far-middle object in scope, then can excitation area 5565 or 5570 to provide+4.625 dioptric total rectifications.During object outside observing the electric excitation district, providing rectification by the optical element of fixed distance, is+4.0 diopters in this embodiment.

This embodiment only is used for illustration purpose, and utilizes other vision prescription also can play same effective function.Below, in table 3, the foregoing description according to exemplary embodiment is described further.This table has also shown the focal power of this electric excitation zone for other different distance visual problems.

Equally, the same with the size and the shape in electric excitation zone, the focal power of describing among this embodiment and the Biao only is exemplary, although this electric excitation zone shown in Figure 55 b is circular, its diameter is 12mm and 28mm, can change according to the needs that the patient observes.

Far-and middle additional optical focal power apart from the zone can be from about 0.25 to about 2.0 diopters, and preferably between 0.25 and 0.75, its expression is near-middle about 50% apart from focal power, and this additional optical focal power approximately is half of the near vision focal power stipulated by convention.Be used for far away-be when adding low coverage or near-middle to when correcting focal power apart from other advantage in the additional lamination electric excitation zone of focal power, far away-middle apart from focal power can accumulate with generate " by force " low coverage and/or " by force " closely-middle apart from focal power.

Zone 5560,5565 and 5570 can all be identical big or small or they can be different sizes.Under the situation in lamination electric excitation zone, when All Ranges all has identical when size, low coverage to closely-middle distance to far-middlely between observing, can not need the Mixed Zone.Provide long distance to observe among the corrigent embodiment by fixing optical element, only need mixing from long-distance region to the electric excitation zone, promptly from low coverage, near-distance or far away-middle distance directly to the transition of long distance.

The order that should be appreciated that zone 5560,5565 and 5570 is not strict, and the present invention can under any circumstance play same effective function.For example, although Figure 55 b is expressed as zone 5560 apart from eyes electric excitation zone farthest, also can be placed between the zone 5565 and 5570.Equally, zone 5560 can be placed as the electric excitation zone nearest apart from eyes.No matter how pile up to generate to observe in these zones is corrected the district, can not influence the performance in these districts.

In another exemplary embodiment, can provide low coverage and near-middle by independent electric excitation zone apart from vision correction.The example of having represented this embodiment among Figure 56, wherein zone 5550 and 5570 can be piled up each other.Zone 5550 can provide low coverage and near-middle apart from the vision correction district.In this embodiment, once only can encourage a zone 5550 or 5570 usually.Do not have an excitation area 5570 if encouraged zone 5550, these lens can provide low coverage and near-middle apart from vision correction so.Generation is used for correcting the district by the near vision that these lens provide the part of full gloss focal power to observe, and in this example, border circular areas has the radius of 6mm.Generation be used for by these lens only provide less near-apart from the part of focal power observe near-middle apart from correcting the district, in this example, deduct the area that near vision is corrected the district, border circular areas has the radius of 14mm.Alternatively, if there is not excitation layer 5550, and encouraged the layer 5570, then these lens can provide far-middle apart from the vision correction district.With the same among other embodiment, can provide distance vision to correct the district in the observation of the outside in electric excitation zone, this district has the focal power of fixed distance optical element.

Although the vision correction area of exemplary embodiment discussed herein is expressed as circle, this zone can have shape arbitrarily, for example is essentially rectangle shown in Figure 57.As shown in this exemplary embodiment, near vision district 5720 and optic zone 5730 can be essentially rectangle, and these two districts can provide by a plurality of stack region of above-mentioned identical size closely-middle distance and/or far away-middle apart from vision.Orthogonal corner can be round.In this exemplary embodiment, the height near vision district 5720 is about 8mm, width is about 18mm, thereby area is about 144mm ²District's width of 5730 is about 28mm, highly is about 28mm, thereby area is about 784mm ²The effective depth of district 5730 when together using with the near vision district with described size is about 10mm.Yet described size only is exemplary; Other size and shape also can.This electric excitation zone does not need to pile up with one heart, in certain embodiments, may need the zone skew of one or more electric excitations.

It is birefringent using the layers of electro-active of liquid crystal.In other words, when it is exposed to non-polarized light following time, they can demonstrate two different focal lengths in unactivated state.This birefringence will produce slur or broad image on retina.Two kinds of methods have been addressed this problem.First kind requires to use at least two layers of electro-active.One deck is that the electric excitation molecule is longitudinally arranged, and another layer then is to make molecule along horizontal orientation in this layer; Thus, the arrangement of molecule is mutually orthogonal in this is two-layer.Like this, two kinds of polarizations of light all can be focused on equally by two liquid crystal layers, and all light all focuses on identical focal length.

This can pile up realization simply by the layers of electro-active that this pairwise orthogonal is arranged, and realizes with possibility that perhaps wherein the central core of these lens is dual platens, and promptly etching has identical diffraction pattern on its both sides.Subsequently, with electro-active material be placed on these central plate both sides the layer in, guarantee both sides the layer in molecules align be orthogonal.Then covering is placed in each electric excitation refractive power matrix above so that it is comprised.This just provides a kind of ratio with the stacked simpler design mutually of two kinds of different electric excitation diffracting layers.

Different possibilities requires people that cholesteryl liquid crystal is added in this electro-active material, so that give its very big chirality composition.Have been found that certain density chiral material can eliminate the polarisation sensitive degree in this plate, thereby need be by two layers of electro-active as the pure nematic crystal of electro-active material composition.
