Main component symbol explanation

[0064] Specific implementation of the application

[0065] Embodiments of the present application will be described below with reference to the accompanying drawings. For the purpose of explanation, numerous specific details will be set forth in the description below. It should be appreciated that these specific details are not intended to limit the present application in any way. Rather, the specific details are included for the purpose of providing a thorough understanding of the present application. It should also be appreciated that the present application is not limited to the embodiments described below, but rather, the present application is capable of being practiced with a wide range of variations. Furthermore, some of the features of the present application could be used to advantage without the use of other features. As such, all such modifications as would be recognized by one skilled in the art to which the present application pertains are intended to be included within the scope of the present application.

[0066] Referring to FIG. 1 and FIG. 2, FIG. 1 is a front view of an embodiment of the smart contact lens of the present application, and FIG. 2 is a cross-sectional view along line A-A of FIG. 1. In the present application, the smart contact lens 100 can have a function of correcting refractive error, and the refractive error includes hyperopia, myopia, astigmatism, presbyopia, or astigmatism-presbyopia; or the smart contact lens 100 can be a makeup lens without the function of correction.

[0067] The smart contact lens 100 includes a lens body 110 and a light adjusting component 120 embedded in the lens body 110. The lens body 110 includes an optical portion S1 and an annular wearing portion S2 surrounding the optical portion S1, wherein the position of the optical portion S1 corresponds to the position of the cornea of the user's eyeball.

[0068] The light adjusting component 120 is embedded in the lens body 110, and the distribution area of the light adjusting component 120 covers the entire optical portion S1. In some embodiments, the light adjusting component 120 includes a first electrode layer 121, a second electrode layer 122, and a first liquid crystal layer 123 disposed between the first electrode layer 121 and the second electrode layer 122. By adjusting the liquid crystal deflection angle of the first liquid crystal layer 123 in the light adjusting component 120, the light transmittance of light passing through the light adjusting component 120 can be changed, thereby allowing the smart contact lens 100 to provide the light shielding function of the sun glasses. In some embodiments, the first electrode layer 121 and the second electrode layer 122 are surface electrodes, and the materials of the first electrode layer 121 and the second electrode layer 122 are transparent conductive materials.

[0069] The smart contact lens 100 further comprises a circuit structure 130 disposed on the annular wearing portion S2, a control chip 140 disposed on the annular wearing portion S2, and a light sensing component 150 disposed on the annular wearing portion S2. The control chip 140 is connected to the light adjusting component 120 via the circuit structure 130, and the light sensing component 150 is connected to the control chip 140 via the circuit structure 130. The control chip 140 adjusts the driving voltage output to the light adjusting component 120 based on the ambient light intensity detected by the light sensing component 150, so as to change the liquid crystal deflection angle of the first liquid crystal layer 123 in the light adjusting component 120, and further adjust the light transmittance of the light adjusting component 120.

[0070] The smart contact lens 100 further comprises a rechargeable power supply 160 disposed on the annular wearing portion S2. The rechargeable power supply 160 is connected to the control chip 140 and the light sensing component 150 via the circuit structure 130, so as to provide the power required by the control chip 140 and the light sensing component 150. In some embodiments, the rechargeable power supply 160 is preferably a coil-induced wireless charging module.

[0071] In some embodiments, the circuit structure 130 comprises a carrier plate 132 and a plurality of circuit lines 134 disposed on the carrier plate 132, and the carrier plate 132 comprises a plurality of slots 136 disposed between the circuit lines 134, thereby improving the oxygen permeability of the smart contact lens 100.

[0072] The lens body 110 has opposite front and back surfaces FS and BS. The back surface BS is used to be worn on the user's eye, and the back surface BS of the optical portion S1 is curved. More specifically, in some embodiments, the back surface BS of the optical portion S1 is a non-spherical (non-semi-spherical) curved surface. As shown in FIG. 2, the curvature of the light adjusting component 120 can be consistent with the curvature of the back surface BS of the optical portion S1.

[0073] Alternatively, referring to FIG. 3, which is a cross-sectional view of another embodiment of the smart contact lens of the present application along the line A-A of FIG. 1. In other embodiments, the light adjusting component 120 can be a plate-shaped structure, and the curvature (almost zero) of the light adjusting component 120 is different from the curvature of the back surface BS of the optical portion S1.

[0074] Referring to FIGS. 4A-4C, which are cross-sectional views of embodiments of the light modulating assembly of the smart contact lens of the present disclosure in different states. The light modulating assembly 120 includes a first electrode layer 121, a second electrode layer 122, and a first liquid crystal layer 123 disposed between the first electrode layer 121 and the second electrode layer 122. The first liquid crystal layer 123 can be a cholesteric liquid crystal layer. Cholesteric liquid crystals (ChLCD) have bistable properties, meaning that there are two stable states in the natural existence state, one of which is a planar state, as shown in FIG. 4A, in which the liquid crystal molecules are arranged in order and can reflect light of a specific wavelength, which is equivalent to filtering light of a specific wavelength. The other state is a focal conic state, as shown in FIG. 4C, in which the liquid crystal molecules are arranged in disorder and scatter incident light, with most of the light penetrating and showing the color underneath the liquid crystal layer. In addition, there is a temporary state, which is a homeotropic state, as shown in FIG. 4B, in which the liquid crystal molecules are all arranged vertically, and light can penetrate completely.

[0075] By changing the electric field applied to the cholesteric first liquid crystal layer 123, the light modulating assembly 120 can be changed between the planar state of FIG. 4A, the homeotropic state of FIG. 4B, or the focal conic state of FIG. 4C. More specifically, the deflection state of the first liquid crystal layer 123 of the light modulating assembly 120 can be adjusted by the strength and speed of the applied electric field, and the electric field applied to the first electrode layer 121 and the second electrode layer 122 of the light modulating assembly 120 can be changed by the driving voltage output by the control chip 140 to the light modulating assembly 120, and the driving voltage output by the control chip 140 to the light modulating assembly 120 is adjusted based on the ambient light intensity detected by the light sensing assembly 150.

[0076] Referring next to FIGS. 5 and 6, which are cross-sectional views of other embodiments of the smart contact lens of the present disclosure, the cross-sectional position being the same as the line segment A-A of FIG. 1. In the embodiments shown in FIGS. 5 and 6, the light modulating assembly 120 of the smart contact lens 100 can provide a color changing function in addition to the light filtering function. Specifically, in addition to the first electrode layer 121, the second electrode layer 122, and the first liquid crystal layer 123, the light modulating assembly 120 further includes a third electrode layer 124, a fourth electrode layer 125, a second liquid crystal layer 126 disposed between the third electrode layer 124 and the fourth electrode layer 125, a fifth electrode layer 127, a sixth electrode layer 128, and a third liquid crystal layer 129 disposed between the fifth electrode layer 127 and the sixth electrode layer 128, and the first liquid crystal layer 123, the second liquid crystal layer 126, and the third liquid crystal layer 129 are in a stacked configuration.

[0077] The lens body 110 has opposite front and back surfaces FS and BS, wherein the back surface BS is configured to be worn on the user's eye, and the back surface BS of the optical portion S1 is curved, more specifically, in some embodiments, the back surface BS of the optical portion S1 is non-spherical (non-hemispherical) curved. As shown in FIG. 5, the curvature of the three-layer liquid crystal layer of the light-adjusting assembly 120 can be consistent with the curvature of the back surface BS of the optical portion S1. Alternatively, as shown in FIG. 6, the light-adjusting assembly 120 can be a plate-like structure, and the curvature (almost zero) of the light-adjusting assembly 120 is different from the curvature of the back surface BS of the optical portion S1.

[0078] In some embodiments, because the setting space of the smart contact lens 100 is limited, the traditional design of reflecting different wavelengths by different liquid crystal rotation is not ideal for the color performance of the smart contact lens 100. Therefore, in the smart contact lens 100, the first liquid crystal layer 123 is a cholesteric liquid crystal layer containing red dye, the second liquid crystal layer 126 is a cholesteric liquid crystal layer containing green dye, and the third liquid crystal layer 129 is a cholesteric liquid crystal layer containing blue dye, so as to realize the function of the variable-tint sunglasses by absorbing light of different wavelengths through the dyed liquid crystal layer and cooperating with different light transmittance.

[0079] Referring to FIGS. 7A to 7C, which are cross-sectional schematic views of embodiments of the light-adjusting assembly in the smart contact lens in different states. As shown in FIG. 7A, if the intensity of the ambient light is too strong, the liquid crystal deflection states of the first liquid crystal layer 123, the second liquid crystal layer 126, and the third liquid crystal layer 129 are all adjusted to be planar. At this time, most of the red light, green light, and blue light in the ambient light are reflected by the first liquid crystal layer 123, the second liquid crystal layer 126, and the third liquid crystal layer 129, so that the amount of light entering the user's eye is extremely low.

[0080] As shown in FIG. 7B, if the intensity of the ambient light is slightly strong, the liquid crystal deflection states of the first liquid crystal layer 123, the second liquid crystal layer 126, and the third liquid crystal layer 129 are all adjusted to be focal conic. At this time, most of the red light, green light, and blue light in the ambient light can pass through the first liquid crystal layer 123, the second liquid crystal layer 126, and the third liquid crystal layer 129, and a small part is reflected by the first liquid crystal layer 123, the second liquid crystal layer 126, and the third liquid crystal layer 129. The light-adjusting assembly 120 is equivalent to being in a half-transmission mode, and the amount of light entering the user's eye is reduced.

[0081] Alternatively, as shown in FIG. 7C, in a specific use environment, such as detecting that the user uses the 3C product for a long time or according to the user's settings, the liquid crystal deflection state of the third liquid crystal layer 129 can be further adjusted, so that most of the blue light band light is reflected in the third liquid crystal layer 129, and most of the red light band light and green light band light can pass through the first liquid crystal layer 123, the second liquid crystal layer 126 and the third liquid crystal layer 129. At this time, the light adjusting assembly 120 is equivalent to being in a yellow light mode, which can achieve the effect of filtering out blue light.

[0082] Next, referring to FIG. 8, it is a front view of another embodiment of the smart contact lens of the present application. In some other embodiments, the smart contact lens 200 can include a lens body 210 and a pattern display assembly 220 embedded in the lens body 210.

The outer diameter of the pattern display assembly 220 can be adjusted and is not limited to this embodiment.

[0083] The pattern display assembly 220 is embedded in the lens body 210, and the distribution area of the light adjusting assembly 120 covers the peripheral area PA and can cover or not cover the central area CA. The pattern display assembly 220 includes a plurality of pixels, each of which can be independently driven to make the pattern display assembly 220 display a specific pattern, so that the smart contact lens 200 provides the function of beauty lenses. The distribution area of the pattern display assembly 220 can also cover the circuit structure 230, so that the smart contact lens 200 provides the function of simulating the iris of the human eye.

[0084] The smart contact lens 200 further includes a circuit structure 230 disposed on the annular wearing part S2, a control chip 240 disposed on the annular wearing part S2, and a transmission module 250 disposed on the annular wearing part S2. The control chip 240 is connected to the pattern display assembly 220 through the circuit structure 230, and the pattern display assembly 220 is connected to the control chip 240 through the circuit structure 230, wherein the control chip 240 adjusts the driving voltage output to each pixel in the pattern display assembly 220 based on the pattern signal received by the transmission module 250, thereby adjusting the display pattern of the pattern display assembly 220.

[0085] The smart contact lens 200 further includes a rechargeable power supply 260 disposed on the annular wearing part S2, and the rechargeable power supply 260 is connected to the control chip 240 and the transmission module 250 through the circuit structure 230 to provide the power required by the control chip 240 and the transmission module 250. In some embodiments, the rechargeable power supply 260 is preferably a coil induction wireless charging module.

[0088] Specifically, as shown in FIG. 9, in each pixel PX of the pattern display assembly 220, the cholesteric liquid crystal layer 224 containing red dye, the cholesteric liquid crystal layer 226 containing green dye, and the cholesteric liquid crystal layer 228 containing blue dye are arranged side by side, and the corresponding electrodes 223 are also arranged side by side.

Further, the pattern signal received by the transmission module 250 of FIG. 8 can be changed, and the control chip 240 can further change the display pattern of the pattern display assembly 220 based on the pattern signal received by the transmission module 250.

[0091] Referring to FIG. 11A and FIG. 11B, a flow chart of an embodiment of the method of manufacturing the smart contact lens of the present application is shown. In some embodiments, the method of manufacturing the smart contact lens starts from step S10, which comprises manufacturing the optical assembly 310. The step of manufacturing the optical assembly 310 comprises disposing the optical assembly 314 on the carrier 312, disposing the circuit 316 on the carrier 312, and disposing the peripheral assembly 318 on the carrier 312. The optical assembly 314 can be a light modulating assembly or a pattern display assembly as mentioned in the previous embodiments. The peripheral assembly 318 comprises a combination of a control chip, a photosensitive assembly, a transmission module, a rechargeable battery, etc. The optical assembly 314 is connected to the peripheral assembly 318 through the circuit 316. In some embodiments, the carrier 312 can be optionally provided with slots between the circuit 316.

[0092] Next, step S12 is to place the optical assembly 310 in the preform mold 410, such as in the female mold 412 of the preform mold 410. In some embodiments, the surface of the female mold 412 of the preform mold 410 used to carry the optical assembly 310 is curved, and the resulting preform is a structure with curvature. In other embodiments (not shown), the surface of the female mold 412 of the preform mold 410 used to carry the optical assembly 310 is flat, and the resulting preform is a plate-like structure. In step S12, the optical assembly 310 preferably contacts the female mold 412 of the preform mold 410 with the carrier 312.

[0093] Next, step S14 is to inject the first contact lens material 320 into the preform mold 410, and to at least partially coat the optical assembly 310 with the first contact lens material 320. The first contact lens material 320 is provided to isolate the optical assembly 314, the circuit 316, and the peripheral assembly 318 in the optical assembly 310 from the external environment, so as to avoid the optical assembly 314, the circuit 316, and the peripheral assembly 318 in the optical assembly 310 from being eroded by moisture or oxygen. In some embodiments, the material of the first contact lens material 320 is a nearly water-free material, for example, a hard high-oxygen permeable contact lens material with a hydration level less than 1.

[0094] Then, step S16 is to perform a molding process, which comprises pressing the male mold 414 and the female mold 412 of the preform mold 410 together, and curing the first contact lens material 320. Next, step S18 is to remove the cured first contact lens material 320 with the optical assembly 310 therein from the preform mold 410, and a preform 330 with the optical assembly 310 embedded therein can be obtained.

[0095] Referring to FIG. 11B, step S20 is to place the extracted preform 330 with the embedded optical component 310 into the female mold 422 of the contact lens mold 420. In some embodiments, the shape of the preform 330 and the shape of the female mold 422 can be matching or non-matching. That is, the shape of the preform 330 can match the shape of the female mold 422 such that one surface of the preform 330 is in contact with the female mold 422 of the contact lens mold 420, or the shape of the preform 330 can not match the shape of the female mold 422 such that there is a gap between one surface of the preform 330 and the female mold 422 of the contact lens mold 420.

[0096] In some embodiments, the female mold 422 of the contact lens mold 420 can be optionally configured with a support 424. The support 424 is configured to support the preform 330 when the shape of the preform 330 does not match the shape of the female mold 422, so that the preform 330 can be reliably positioned on the female mold 422 of the contact lens mold 420.

[0097] The method of manufacturing the smart contact lens then proceeds to step S22, which is to inject a second contact lens material 340 into the female mold 422 of the contact lens mold 420, so that the preform 330 with the embedded optical component 310 is at least partially covered by the second contact lens material 340. Then, step S24 is to perform a molding process, which includes pressing the male mold 426 and the female mold 422 of the contact lens mold 420 together, and curing the second contact lens material 340.

[0098] In some embodiments, the material properties of the second contact lens material 340 are the same as or different from the material properties of the first contact lens material 320. Specifically, the water content of the second contact lens material 340 can be the same as or higher than the water content of the first contact lens material 320, or the first contact lens material 320 and the second contact lens material 340 are selected to be different contact lens materials. In some embodiments, the first contact lens material 320 and the second contact lens material 340 can be different hard contact lens materials with different water contents. In other embodiments, the first contact lens material 320 is a hard contact lens material with a low water content, and the second contact lens material 340 is a soft contact lens material.

[0099] In some embodiments, if the shape of the preform 330 matches the shape of the male mold 426 or the female mold 422 of the contact lens mold 420, the second contact lens material 340 can only partially coat the preform 330, leaving part of the surface of the preform 330 uncovered by the second contact lens material 340. Alternatively, if the shape of the preform 330 does not match the shape of the male mold 426 or the female mold 422 of the contact lens mold 420, the preform 330 can be almost completely coated by the second contact lens material 340. In this case, the solidified second contact lens material 340 can also be referred to as a housing portion 350, and the preform 330 is embedded in the housing portion 350.

[0100] Finally, after the second contact lens material 340 is solidified, the smart contact lens 500 is removed in step S26. The smart contact lens 500 comprises a lens body 510 and an optical assembly 310 embedded in the lens body 510, wherein the lens body 510 comprises a preform 330 and a housing portion 350 embedded in each other, the optical assembly 310 is embedded in the preform 330, and the material properties of the preform 330 are the same as or different from the material properties of the housing portion 350.

[0101] Referring to FIG. 12, it is a flowchart of another embodiment of a manufacturing method of a smart contact lens of the present application. In other embodiments of the manufacturing method of a smart contact lens, as shown in step S30, the preform 330 embedded with the optical assembly 310 and the housing portion 350 can also be independently manufactured, and then bonded and fixed by the adhesive 360, as shown in step S32, to obtain the smart contact lens 500. The manufacturing of the preform 330 embedded with the optical assembly 310 can refer to steps S10 to S18 in FIG. 11A.

Then, the solidified second contact lens material 340 is removed from the contact lens mold 420. Then, as shown in step S34, the solidified second contact lens material 340 is cut to obtain the housing portion 350 with a receiving cavity 352. According to another embodiment, depending on the front and back arc shapes of the housing portion 350, a hard high-oxygen-permeable contact lens round ingot material can also be used, which is obtained by lathe machining, as shown in FIG. 13.

[0103] Alternatively, referring to FIG. 14, it is a schematic diagram of another embodiment of a method of making a housing portion of the smart contact lens of the present application. The method of making a housing portion includes injecting a second contact lens material 340 into a housing portion mold 460, pressing a male mold 464 of the housing portion mold 460 against a female mold 462, and curing the second contact lens material 340. Then, as shown in step S42, the cured second contact lens material 340 is removed from the housing portion mold 460, and a housing portion 350 with a receiving cavity 352 is obtained.

[0104] It is noted that the shape of the receiving cavity 352 of the housing portion 350 made according to either FIG. 13 or FIG. 14 can be designed according to the final design of the smart contact lens 500. In some embodiments, the receiving cavity 352 can be located on the front surface or the back surface of the lens body 510 (see FIG. 12). In some embodiments, the shape of the receiving cavity 352 of the housing portion 350 can match or not match the shape of the preform 330 (see FIG. 12).
