As shown in fig. 1, disclose a kind of method of making electro-active lens.Described method comprises provides lenticular blank, shown in step 10.Described lenticular blank can be the lenticular blank of any kind of, and has front surface and rear surface, certain thickness and refractive index.In step 20, electrically active component is placed on the front surface or rear surface of lenticular blank.In step 30, on the surface of the lenticular blank that comprises electrically active component, form overlayer.This overlayer is protected described electrically active component, and electrically active component is fixed on a certain position on the lenticular blank.Being used for forming tectal material can also combine with lenticular blank, for the wearer of lens provides the fixed range vision correction.
Described electrically active component comprises one or more layers electroactive material, as polymer gel and/or liquid crystal, when being subjected to the excitation of impressed voltage, produces the refractive index that the size with adding to electroactive material voltage changes.When the wearer when comprising the electro-active lens regional observation of electrically active component, based on the electrically active component refractive index, the wearer can realize vision correction, this can be the vision correction except that the vision correction that the non-electroactive part of lens provides.Suitable electroactive material comprises all kinds of liquid crystal and polymer gel.These kinds comprise nematic, smectic type and cholesteryl liquid crystal, and comprise polymer liquid crystal, and Polymer Dispersed Liquid Crystal and polymer stabilizing liquid crystal also have electro-optic polymer.
If the use liquid crystal such as nematic crystal, as electroactive material, then needs oriented layer, because nematic and many other liquid crystal all are birefringent.When promptly being exposed to nonpolarized light there not being impressed voltage, it demonstrates two different focal lengths.This birefringence causes producing on the retina two or fuzzy image.In order to alleviate this birefringence, can use the second layer electroactive material vertical orientated with the ground floor electroactive material.In this way, by two-layer two kinds of polarization states are focused on equally, and all light all focus on the same focal length place.
Select as another, can use cholesteryl liquid crystal, as preferred electroactive material with big chirality composition.Different with other liquid crystal commonly used with nematic, cholesteryl liquid crystal does not have the polarity of nematic crystal, thereby need not the multilayer electroactive material.
Described the various electroactive layers that can be used in the embodiment of the invention electrically active component among the PCT/US03/12528 that on April 23rd, 2003 submitted, this application is in this hereby incorporated by reference.
Lenticular blank can be the lenticular blank of any kind, and for example comprises the semi-manufacture blank, do not finish blank, lens wafers, prefabricated optical devices or finished lens.Can seal by conformal,, perhaps pass through to cover lenticular blank to form overlayer with lens wafers as by molded or surperficial casting.
According to an embodiment of the present invention, make electro-active lens by the semi-manufacture blank, have the overlayer that forms by the conformal sealing.Described electrically active component can be placed on the front surface or rear surface of semi-manufacture blank.Conformal is sealed in and forms the protection overlayer on the surface that is placed with electrically active component of lenticular blank, and electrically active component is imbedded in the lens.Fig. 2 is a kind of embodiment of the present invention, a kind of process flow diagram that uses the semi-manufacture blank manufacturing electro-active lens method of conformal sealing of its explanation.Fig. 2 A-E explanation is in the lens in each stage of method shown in Figure 2.In step 100, can select to have the semi-manufacture blank 230 of back concave surface 202 and convex front surface 204, shown in Fig. 2 A.In step 110, as shown in Fig. 2 B, in the convex front surface 204 of semi-manufacture blank 230, cut out groove 205.In step 120, electrically active component 200 can be positioned in the groove 205.In addition, the conductive bus 210 that is connected with electrically active component 200 can be placed in the groove 205.Preferably by optically transparent flexible material, constitute described conductive bus 210 as the extruding of the ophthalmology level material of tin indium oxide or casting polymer film and/or conducting polymer such as scribbling transparent conductive material.Conductive bus 210 can have a plurality of apertures, and this can promote conductive bus and lenticular blank 230 bonding better.
In step 130, as shown in Fig. 2 D, can use to include the sealant that preferred its refractive index was similar to or equaled the lenticular blank refractive index, as the mould 220 of optical clear resin, electrically active component 200 and conductive bus 210 conformals are sealed in the semi-manufacture blank 230.
Electrically active component 200 and conductive bus 210 are positioned in the mould 220, and cover at the top with lenticular blank 230.Can only make resin solidification by heat energy, luminous energy or the two combination.Light source can comprise any one or its combination in the middle of visible light source, ultraviolet source or the infrared light supply.
In step 140, shown in Fig. 2 E, make 230 demouldings of semi-manufacture blank, make semi-finished product cell electro-active lens blank 235.The resin that solidifies forms overlayer 215 on convex front surface 204, it has imbeds the interior effect of electro-active lens to electrically active component 200 and conductive bus 210.Electro-active lens blank 235 has covering surfaces 208, and this surperficial radius-of-curvature equals the radius-of-curvature of mould 220.The radius-of-curvature of covering surfaces 208 combines with the radius-of-curvature of back concave surface 202, and fixing refractive power is provided.
Can be selectively give lens in addition hard anti-zoned coating, shown in step 150.Can before finishing semi-finished product cell electro-active lens blank 235, obtain described hard coating by dipping or spin coating lens.Will be understood that, can be before arriving the convex front surface 204 of lenticular blank with resin fill mold 220 and with resin solidification, described hard coating is put on the inside surface of mould 220, thereby when resin solidification with when forming overlayer, this hard coating has been on the covering surfaces 208.
In step 160, as shown in Fig. 2 F, can pass through known technology, the described electro-active lens blank 235 of surface working makes semi-finished product cell electro-active lens blank 235 be trimmed to required specification, makes electro-active lens 240.Electro-active lens 240 edge treated can be formed in spectacle-frame subsequently adapts.
The convex front surface 204 and the back concave surface 202 that should be appreciated that lenticular blank 230 can have any flexibility or not have flexibility, and this can implemented by the kinds of surface process technology after a while.Hide electrically active component 200 and conductive bus 210 in case lenticular blank 230 is sealed by conformal, after then finishing, just give the flexibility of back concave surface 202 and covering surfaces 208 (being not convex front surface 204), the optical property of decision electro-active lens 240.
According to a kind of embodiment of the present invention, use prefabricated optical devices when making electro-active lens, be such as but not limited to finished product or single vision lens.Fig. 6 represents to use with top and forms overlayer with reference to the described similar conformal encapsulating method of Fig. 2, so that electrically active component is covered in the lens, thereby is made the method for electrically active component by the lenticular blank with single vision lens.But, different with the described semi-manufacture blank of reference Fig. 2 method, single vision lens has had certain specification, need not further to carry out surface working and comes to provide appropriate fixed optical power for the wearer of lens.Thereby, in the present embodiment, preferably carry out the conformal sealing in the following manner, so that do not change the refractive power of original finished lens.Such as, can be by using mould, the radius-of-curvature that produces the convex front surface radius-of-curvature that equals single vision lens on tectal covering surfaces realizes this point.But, even should be appreciated that use finished product single vision lens, if necessary, also can use mould to produce and have covering surfaces, this covering surfaces has the overlayer of the required curvature different with the single vision lens convex front surface, thereby changes refractive power.
As shown in Figure 6, in step 700, just as among Fig. 6 A further expression, can select the basic lens 800 of single vision.In step 710,, can cut out groove 810 in the convex front surface 804 with the basic lens 800 of single vision shown in Fig. 6 B.As another selection, the basic lens 800 of single vision can have groove 810, such as, in basic lens 800 initial manufacture of single vision, can in the basic lens 800 of single vision, form.In step 720,, electrically active component 200 and conductive bus 210 are positioned in the groove 810 just like such shown in Fig. 6 C.In step 730, use the mould 820 that contains resin, with electrically active component 200 and bus 210 conformals sealing, promptly as shown in Fig. 6 D.In step 740, remove mould 820, and can select to apply hard coating.In certain embodiments, in the conformal seal process, shift described hard conating from mould.In this case, be used for making the inner concave of the mould of overlayer projection coverage rate 808, should scribble the hard conating resin in advance, in the conformal seal process, described hard conating resin can take place to solidify and shift.Because the basic lens of single vision described in this example, before the conformal sealing, be trimmed to and had required fixed optical power, the inside surface of mould 820 is preferably the concave surface of radius-of-curvature that radius-of-curvature equals the convex front surface 804 of the basic lens 800 of single vision.Like this, just like such shown in Fig. 6 E, when mould 820 is removed the basic lens 800 of single vision, just produce curvature and convex front surface 804 essentially identical protruding coverage rates 808 in conformal sealing back, cause the fixed optical power change of the basic lens 800 of single vision very little or do not change.
In the electro-active lens manufacture process, use the conformal sealing, the quantity of the holding member (SKU) 539 that can reduce to get the raw materials ready, this with conventional lenses usually the quantity of required SKU compare, be significantly reduced.
In order to understand this improved meaning, must understand the quantity that is used to solve the required conventional lenses blank of most variations.Be about 95% correcting scheme comprise-6.00 diopters in+6.00 diopter scopes, step-length is that 0.25 dioptric spherical diopter is proofreaied and correct.According to this scope, has the spherical diopter of about 49 routine prescription.Certainly, in comprising the scheme of astigmatism correction, be about 90% be in-4.00 diopters in+4.00 dioptric scopes, step-length is 0.25 diopter.According to this scope, has astigmatism (or cylinder) diopter of about 33 routine prescription.But, because astigmatism has axial component, have the astigmatism axle orientation of about 180 degree, the regulation step-length is 1 degree usually.Thereby, 180 different astigmatic axis prescriptions are arranged.
In addition, many schemes comprise and are used to proofread and correct presbyopic bifocal component.Have in the scheme of presbyopia corrective at these, be about 95% be in+1.00 to+3.00 diopter scopes in, step-length is 0.25 diopter, thereby produces the presbyopia's diopter that is about 9 routine prescription.
This causes 2,619, the individual possible different lens arrangement in 540 (49 * 33 * 180 * 9), and lens manufacturers needs very a large amount of SKU.Because can be used for the raw-material diversity that lens are made, and other specific characteristics that can comprise in the lens, such as photochromic colourity, the number of this larger amt SKU is further increased.Electroactive by most of vision corrections are had, can significantly reduce the quantity of SKU.
In another embodiment of the present invention, by two lens wafers are fixed together, electrically active component is clipped between two lens wafers, make electro-active lens.
As shown in Figure 7,, select front lens wafer and back lens wafer to have required optical property, obtain the fixed range refractive power, so that be complementary with wearer's vision scheme in step 1000.Shown in Fig. 7 A, select concave back lens wafer 900 and convex front lens wafer 930.Front lens wafer 930 can have radius of curvature R 1, and back lens wafer 900 can have radius of curvature R 2.The fixed optical power of lens wafers equals (n-1) * (1/R1-1/R2), and wherein " n " equals to make the refractive index of lens wafers material therefor.Wherein R1 is similar each other to R2, and it is 0 that the basic lens that form by the fixed lens wafer have fixing refractive power.
For other electro-active lens as herein described, (this provides refractive power usually by increasing fixed optical power, so that distance vision is provided to be proofreaied and correct), the refractive power that provides when watching by the electro-active lens zone that comprises electrically active component is provided, produces and be used for that near vision is proofreaied and correct and the refractive power of mesopic vision correction.But, should be appreciated that any lens to be manufactured to have null fixed optical power, thereby watch, all vision corrections can be provided by the electro-active lens zone that comprises electrically active component.Equally, watch, the correction to unconventional ametropia can be provided, comprise at all focus correction higher order aberrations by the lens area that comprises electrically active component.
Should further understand,, but, can only use basic lens or, proofread and correct unconventional ametropia in conjunction with electrically active component although use habitual casting, free form manufacturing or photon-induced refractive index to change or photic refraction change.In these embodiments, basic lens can be independent of the correction that electrically active component provides unconventional ametropia, and this can proofread and correct the sphere refractive power relevant with conventional ametropia and regulate or error, such as the presbyopia.
Refer again to Fig. 7 A, can with the convex surface facing surfaces of front lens wafer 903 and with the concave surface facing surfaces of back lens wafer 900 in the middle of one of or both in cut out groove.As another selection, described groove is present in the lens wafers 900,930 already, produces in advance as during fabrication.Fig. 7 A represents front lens wafer 930, with the convex surface facing surfaces of front lens wafer 930 in have single groove 940.Electrically active component 910 and flexible conductive bus 920 can be positioned between back lens wafer 900 and the front lens wafer 930, and electrically active component 910 and compliant conductive bus 920 are arranged to be in the groove 940.As shown in step 1030, can utilize the bonding agent of index matched that front lens wafer 930 and back lens wafer 900 are bonded together, make electro-active lens.
In certain embodiments, can make back lens wafer that the cylinder refractive power is provided by stacked lens wafers, and combination back lens wafer and front lens wafer, realize the sphere refractive power of lens, thereby make electro-active lens.
