DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The following describes the implementation of the "contact lens" disclosed by the present invention through certain specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the disclosure of this specification. The present invention can be implemented or applied through other different specific embodiments. Each detail in this specification can be modified and changed equivalently based on different perspectives or applications without departing from the spirit of the present invention. In addition, the drawings of the present invention are for simple and schematic illustration only and do not represent actual dimensions. The following embodiments will further describe the technical contents of the present invention, but the disclosed contents do not limit the protection scope of the present invention.

[0028] Throughout this specification, terms such as "first," "second," and "third" may be used to describe various components or signals, but it should be understood that these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another or one signal from another. Furthermore, the term "or" as used herein may include any one or combination of the associated listed items, depending on the actual situation.

[0029] [First embodiment] Please refer to the first embodiment of the present invention shown in Figures 1 to 9. As shown in Figures 1 to 6, in this embodiment, a contact lens 100 (also called a smart contact lens) is disclosed. The contact lens 100 can be worn on a user's eye 200 (e.g., Figure 3) or implanted in the eye 200 (not shown) depending on design requirements.

[0030] Furthermore, in this embodiment, the contact lens 100 may have a function of correcting refractive errors, including hyperopia, myopia, astigmatism, presbyopia, or astigmatism-presbyopia, or the contact lens 100 may be a makeup lens without a corrective function.

[0031] In this embodiment, the contact lens 100 includes a lens body 1 and a built-in module 10 embedded in the lens body 1. The built-in module 10 includes a front support ring 4, a rear support ring 5 facing the front support ring 4, an electronic component 2 sandwiched between the front support ring 4 and the rear support ring 5, and a wiring structure 3 sandwiched between the front support ring 4 and the rear support ring 5 and electrically coupled to the electronic component 2, but the present invention is not limited thereto. For example, in other embodiments not shown in the drawings, the built-in module 10 may include only the front support ring 4, the rear support ring 5, and the wiring structure 3, and may omit the electronic component 2, depending on design requirements. In addition, the front support ring 4 and the rear support ring 5 may each be regarded as a support. Hereinafter, each component of the contact lens 100 of this embodiment will be described in order, and the connection relationship between multiple components will be described as appropriate.

[0032] In this embodiment, the lens body 1 is formed by hardening hydrogel or silicone hydrogel, and the hydrogel is, for example, p-HEMA, but is not limited thereto. The lens body 1 includes an optical part 11 and a ring-shaped wearing part 12 surrounding the optical part 11, and the optical part 11 can be configured to have or not have a function of correcting refractive error according to design requirements. It should be noted that, although the optical part 11 does not have any components embedded therein in this embodiment, components may be embedded in the optical part 11 according to design requirements, such as when the contact lens 100 is applied to a digital zoom device, and is not limited to the above description of this embodiment.

[0033] Furthermore, a central axis L is defined in the optical part 11, and the center of the optical part 11 and the center of the ring-shaped wearing part 12 are both located on the central axis L. The ring-shaped wearing part 12 is connected to the outer edge of the optical part 11 and has a substantially circular ring shape. The built-in module 10 is embedded inside the ring-shaped wearing part 12. In addition, the production method for embedding the built-in module 10 in the ring-shaped wearing part 12 (or the manufacturing method of the contact lens 100) can be adjusted or changed according to design requirements, and the present invention is not limited thereto.

[0034] More specifically, the built-in module 10 is embedded in the ring-shaped wearing part 12, and the front support ring 4 and the rear support ring 5 respectively surround the outside of the optical part, and both centers are located on the central axis line L. The front support ring 4 has a front curved surface 41 and a rear carrier surface 42, and the rear support ring 5 has a rear curved surface 51 and a front carrier surface 52 facing the rear carrier surface 41.

[0035] More specifically, both the electronic component 2 and the wiring structure 3 are sandwiched and positioned between the rear carrier surface 42 of the front support ring 4 and the front carrier surface 52 of the rear support ring 5, so that the electronic component 2 and the wiring structure 3 are completely embedded in the ring-shaped wearing part 12. In this embodiment, at least one of the front support ring 4 and the rear support ring 5 covers the entire electronic component 2 and the entire wiring structure 3 (along the central axis L), but is not limited to this. In addition, both the side edges of the electronic component 2 and the side edges of the wiring structure 3 are connected to the ring-shaped wearing part 12 (for example, the lower eyelid region 122 described below) without any gaps.

[0036] Furthermore, in this embodiment, the front support ring 4 and the rear support ring 5 are each made of an eye-friendly material, and the eye-friendly material may include hydrogel (e.g., p-HEMA) or silicone hydrogel. Note that, although it is desirable that the characteristics (e.g., oxygen permeability) of the material adopted by the front support ring 4 and the rear support ring 5 are similar to the material characteristics of the lens body 1, they may be made of a material different from the material of the lens body 1 according to design requirements, and the present invention is not limited thereto.

[0037] As described above, the contact lens 100 disclosed in the embodiment of the present invention has the front support ring 4 and the rear support ring 5 made of an eye-friendly material, which clamps and positions the wiring structure 3 (and the electronic component 2), thereby achieving high-precision positioning of the wiring structure 3 (and the electronic component 2) in the production and manufacturing process of the contact lens 100 and maintaining high consistency during mass production of the contact lens 100.

[0038] More specifically, when the wiring structure 3 (and the electronic components 2) are placed in a molding die (not shown), a plurality of positioning structures in the molding die abut against the front support ring 4 and the rear support ring 5, thereby accurately positioning the wiring structure 3 (and the electronic components 2) at a predetermined position, which is advantageous for forming the lens body 1 that is injected and hardened in the molding die to cover the built-in module 10. After the contact lens 100 is removed from the molding die, the front support ring 4 and the rear support ring 5 that abut against the plurality of positioning structures are formed with a front curved surface 41 and a rear curved surface 51, respectively.

[0039] More specifically, the ring-shaped wearing part 12 has a C-shaped layout area 121 and a lower eyelid area 122 located between both ends of the layout area 121, and the electronic component 2 is embedded in the lower eyelid area 122. When the contact lens 100 is worn on the eye 200, the positions of the lower eyelid area 122 and the electronic component 2 correspond to the lower eyelid 201 of the eye 200, which has a relatively low sensitivity, thereby effectively reducing the foreign body sensation of the user.

[0040] Viewed from another angle, as shown in Fig. 2 to Fig. 6, the surface of the lens body 1 includes a rear surface 1b and a front surface 1a located opposite to the rear surface 1b. Note that the rear curved surface 51 of the rear support ring 5 is aligned with the rear surface 1b of the lens body 1, thereby jointly forming a predetermined curvature suitable for wearing on the eye 200 of the user. That is, the value of the predetermined curvature is related only to the eye 200. Furthermore, the rear curved surface 51 of the rear support ring 5 and the rear surface 1b of the lens body 1 are preferably not formed with any recess (or hole), but the present invention is not limited thereto.

[0041] In addition, the front surface 1a has a visible surface 11a corresponding to the optical part 11, and the front curved surface 41 is aligned with the front surface 1a to jointly form a free curved surface 12a corresponding to the ring-shaped wearing part 12. The front curved surface 41 of the front support ring 4 and the front surface 1a of the lens body 1 preferably do not have any recesses (or holes), but the present invention is not limited thereto. That is, the outer surface of the contact lens 100 does not have any recesses (or holes). In addition, the visible surface 11a has a first curvature related to the optical design required to correct refractive errors, or the first curvature of the visible surface 11a can form a structure with no power in cooperation with the rear surface 1b.

[0042] Moreover, the first curvature of the visible surface 11a is different from the second curvature of the free-form surface 12a, so that the thickness distribution of the ring-shaped wearing part 12 gradually increases toward the electronic component 2 (e.g., the lower eyelid region 122), but the present invention is not limited thereto. For example, in another embodiment of the present invention (not shown), the first curvature is substantially equal to the second curvature, and the thicknesses of the ring-shaped wearing part 12 may be substantially equal.

[0043] From another perspective, the contact lens 100 can have at least one electronic component 2 embedded in any one of the ring-shaped wearing part 12 via the front support ring 4 and the rear support ring 5 according to design requirements. For example, in another embodiment (not shown) of the present invention, at least one electronic component 2 is embedded in each of the horizontal sides of the ring-shaped wearing part 12 via the front support ring 4 and the rear support ring 5, so that the thickness of the ring-shaped wearing part 12 is the thickest in the horizontal direction of the eye and gradually becomes thinner in the vertical direction of the eye. This setting method can accommodate at least two sets of the electronic components 2, thereby reducing the foreign body sensation when wearing the contact lens 100.

[0044] As described above, in the contact lens 100 disclosed in the embodiment of the present invention, the front surface 1a of the lens body 1 and the front curved surface 41 of the front support ring 4 jointly form the free curved surface 12a, so that the thickness of the layout region 121 does not need to be perfectly matched to the thickness of the lower eyelid region 122. As a result, the layout region 121 can be made thinner, thereby effectively improving the oxygen permeability of the layout region 121 and reducing the foreign body sensation when the contact lens 100 is worn.

[0045] In order to further effectively improve the oxygen permeability of the layout region 121 and reduce the foreign body sensation when the contact lens 100 is worn, it is desirable for the contact lens 100 to have at least one of the following characteristics by adjusting the second curvature of the free-form surface 12a, but the present invention is not limited thereto.

[0046] The maximum thickness Tmax of the ring-shaped wearing part 12 (and / or the built-in module 10) is located in the area where the electronic component 2 is arranged (e.g., the lower eyelid area 122), and the minimum thickness Tmin of the ring-shaped wearing part 12 (and / or the built-in module 10) is located in a portion of the layout area 121 away from the lower eyelid area 122 (e.g., the top of the layout area 121 in FIG. 4). In other words, when the contact lens 100 is worn on the eye 200, the portion having the maximum thickness Tmax in the ring-shaped wearing part 12 (and / or the built-in module 10) corresponds to the lower eyelid 201 of the eye 200, and the portion having the minimum thickness Tmin in the ring-shaped wearing part 12 (and / or the built-in module 10) corresponds to the upper eyelid 202 of the eye 200. In this embodiment, the maximum thickness Tmax and minimum thickness Tmin correspond to the user's lower eyelid 201 and upper eyelid 202, but the present invention does not limit the relative positional relationship between the thickness of the contact lens 100 and the user's upper eyelid 201 and lower eyelid 202 to this.

[0047] The wiring structure 3 may exist alone in the embedded module 10 (not shown) or in combination with the electronic components 2, and may be electrically or physically driven to realize at least one of a number of functions, such as receiving energy, transmitting wireless signals, digital calculation, sensor monitoring, applying pressure, emitting current, projecting images, optical zoom, and storing power, although the present invention is not limited thereto.

[0048] It should be noted that, as shown in Figures 1 to 6, in this embodiment, the wiring structure 3 includes a carrier substrate 31 and wirings 32 (e.g., metal wirings) formed on the carrier substrate 31, and the wirings 32 are connected to and electrically coupled with the electronic components 2, but the present invention is not limited thereto. For example, as shown in Figures 7 to 9, the wiring structure 3 includes wirings 32 connected to the electronic components 2, and the wirings 32 may not be formed on any carrier substrate. That is, the built-in module 10 pre-positions the wirings 32 by the front support ring 4 and the rear support ring 5, thereby preventing the wirings 32 from moving or deforming when the lens body 1 is molded.

[0049] In this embodiment, as shown in Figures 1 to 6, the carrier substrate 31 is molded into a predetermined curved structure through room temperature or high temperature compression of a press molding die, so that the carrier substrate 31 has a molded curvature different from the second curvature, and the molded curvature is preferably close to the predetermined curvature formed by the rear surface 1b and the rear curved surface 51 (for example, it is preferable that the molded curvature is 100% to 110% of the predetermined curvature), but the present invention is not limited thereto.

[0050] In this embodiment, the carrier substrate 31 is a flexible printed circuit board (FPCB) having a thickness of 10 μm to 300 μm, and the thickness of the carrier substrate 31 is preferably 40 μm to 80 μm. The polymer material of the carrier substrate 31 may include, but is not limited to, polyimide (PI), liquid crystal polymer (LCP), polyethylene terephthalate (PET), or polyethylene 2,6-naphthalene dicarboxylate (PEN).

[0051] More specifically, the carrier substrate 31 has a C-shaped segment 311 embedded in the layout region 121 and a connection segment 312 embedded in the lower eyelid region 122, and the connection segment 312 is connected between both ends of the C-shaped segment 311. The electronic component 2 is attached to the connection segment 312, and the wiring 32 is formed in the C-shaped segment 311 and extends to the connection segment 312 to be connected to the electronic component 2.

[0052] Furthermore, since the carrier substrate 31 is prone to wrinkles and stress concentration during the pressure molding process, at least one through hole 3111 is formed in the C-shaped segment 311, and the lens body 1 (for example, the ring-shaped wearing part 12) is filled in at least one of the through holes 3111. It should be noted that in the top view of the contact lens 100 (along the central axis L), the area of ​​at least one of the through holes 3111 must occupy 1% to 85% (preferably 10% to 40%) of the area surrounded by the outer contour of the C-shaped segment 311. This effectively reduces the occurrence of wrinkles and stress concentration in the carrier substrate 31, and further improves the oxygen permeability of the contact lens 100 in combination with the free-form surface 12a.

[0053] In addition, the carrier substrate 31 may have a plurality of radial cuts 313 formed from its outer edge toward the central axis L, which facilitates the carrier substrate 31 to form the formed curvature and further reduces the occurrence of wrinkles and stress concentration on the carrier substrate 31. The ring-shaped wearing part 12 is filled into the plurality of radial cuts 313, and the plurality of radial cuts 313 are respectively formed at the boundaries between the C-shaped segment 311 and the connecting segment 312 in this embodiment, but the present invention is not limited thereto.

[0054] Further, in a top view of the contact lens 100, the area of ​​the at least one through hole 3111 occupies 1% to 75% of the area of ​​the ring-shaped wearing part 12. In this embodiment, the number of the at least one through hole 3111 formed in the C-shaped segment 311 is described as being plural, but the present invention is not limited thereto. For example, in other embodiments not shown in the drawings of the present invention, the C-shaped segment 311 of the carrier substrate 31 may not have any through hole 3111 formed therein.

[0055] In this embodiment, the wiring 32 is surrounded to form at least one closed circuit, and the plurality of through holes 3111 of the C-shaped segment 311 are located within the at least one closed circuit of the wiring 32. It should be noted that in this embodiment, the number of the at least one closed circuit is described as a plurality, and the plurality of through holes 3111 are respectively located within the plurality of closed circuits of the wiring 32, but the present invention is not limited thereto.

[0056] Each of the through holes 3111 has a curved shape, and the width of any one of the through holes 3111 gradually increases from both ends toward the center (for example, in this embodiment, the through holes 3111 have a roughly crescent shape). More specifically, any one of the through holes 3111 has an inner hole edge 3112 and an outer hole edge 3113, and both ends of the inner hole edge 3112 are connected to both ends of the outer hole edge 3113, respectively, thereby constituting both ends of at least one of the through holes 3111.

[0057] In addition, the inner hole edge 3112 and the outer hole edge 3113 are both arc-shaped, the radius of the inner hole edge 3112 is smaller than the radius of the outer hole edge 3113, and the center of the inner hole edge 3112 and the center of the outer hole edge 3113 are respectively located on two different planes perpendicular to the central axis L. That is, in this embodiment, each of the through holes 3111 is arranged along the molding curvature of the carrier substrate 31 and is not planar.

[0058] In order to define the distribution of the plurality of through holes 3111 more clearly, the central axis L is defined as the origin, and X-axis and Y-axis are defined from the origin and intersect with the origin, being perpendicular to each other, in the top view of the contact lens 100. This divides the contact lens 100 into a first quadrant Q1, a second quadrant Q2, a third quadrant Q3, and a fourth quadrant Q4 in the counterclockwise direction.

Furthermore, the value of the central angle σ122 may be determined according to design requirements, and the present invention is not limited thereto.

[0060] Furthermore, when viewed from the top of the contact lens 100, the multiple through holes 3111 are distributed in the first quadrant Q1, the second quadrant Q2, the third quadrant Q3 and the fourth quadrant Q4, and among the multiple locations of the multiple through holes 3111 distributed in the first quadrant Q1, the second quadrant Q2, the third quadrant Q3 and the fourth quadrant Q4, the area difference between any two locations does not exceed 50%.

[0061] More specifically, in a top view of the contact lens 100, any one of the through holes 3111 may span at least two quadrants (for example, any one of the through holes 3111 may be located in the first quadrant Q1 and the fourth quadrant Q4, or in the second quadrant Q2 and the third quadrant Q3), and any one of the through holes 3111 may be mirror-symmetric with respect to the X-axis, but the present invention is not limited thereto.

Note that the plurality of first through holes 3111a are located inside the plurality of second through holes 3111b, respectively. That is, the radius of each of the second through holes 3111b is different (for example, larger) than the radius of any one of the first through holes 3111a.

[0063] In this embodiment, each of the first through holes 3111a has an arc shape, its center is located on the central axis L, and the first through holes 3111a are spaced apart from one another. Also, each of the second through holes 3111b has an arc shape, its center is located on the central axis L, and the second through holes 3111b are spaced apart from one another.

[0066] Furthermore, in this embodiment, it has been described that the built-in module 10 sandwiches the wiring structure 3 and the electronic components 2 between the front support ring 4 and the rear support ring 5, but the present invention is not limited thereto.

The differences between this embodiment and the first embodiment will be roughly described.

[0069] In this embodiment, each of the through holes 3111 is elongated and has a shape of approximately equal width, and the carrier substrate 31 has a plurality of radial cuts 313 formed from its outer edge toward the central axis L.

[0070] More specifically, in a top view of the contact lens 100, the area of ​​the plurality of through holes 3111 distributed in the first quadrant Q1 and the second quadrant Q2 can be larger than the area of ​​the plurality of through holes 3111 distributed in the third quadrant Q3 and the fourth quadrant Q4.

[0071] Furthermore, the plurality of through holes 3111 include a plurality of first through holes 3111a and a plurality of second through holes 3111b.

That is, the front support ring 4 covers the entire wiring structure 3 and the entire electronic component 2 (along the central axis L), and the electronic component 2 and the wiring structure 3 are connected to the ring-shaped mounting part 12 without any gaps.

[0076] In addition, in this embodiment, the wiring structure 2 is described as including the carrier substrate 31 and the wiring 32, and the structure of the carrier substrate 31 is similar to the example shown in Figures 1 and 2 of the first embodiment, but the present invention is not limited thereto.

[0077] In addition, in this embodiment, the built-in module 10 is described as connecting the wiring structure 3 and the electronic components 2 by the front support ring 4, but the present invention is not limited thereto.

[0081] More specifically, the electronic component 2 and the wiring structure 3 are coupled to the front carrier surface 52 of the rear support ring 5 so that the electronic component 2 and the wiring structure 3 are completely embedded in the ring-shaped mounting part 12 (e.g., the built-in module 10 is not in contact with the front surface 1a but is spaced apart from it). That is, the rear support ring 5 covers the entire wiring structure 3 and the entire electronic component 2 (along the central axis L), and the electronic component 2 and the wiring structure 3 are connected to the ring-shaped mounting part 12 without any gaps.

[0082] In addition, in this embodiment, the wiring structure 2 is described as including the carrier substrate 31 and the wiring 32, and the structure of the carrier substrate 31 is similar to the example shown in Figures 1 and 2 of the first embodiment, but the present invention is not limited thereto.

[0085] [Technical Effects of the Embodiments of the Present Invention] As described above, the contact lens disclosed in the embodiment of the present invention positions the wiring structure (and the electronic components) by forming the front support ring, the rear support ring, and at least one of the multiple supports from the eye-friendly material, thereby achieving high-precision positioning of the wiring structure (and the electronic components) in the contact lens production manufacturing process, and thereby maintaining high consistency during mass production of contact lenses.

[0086] In addition, in the contact lens disclosed in the embodiment of the present invention, the front surface of the lens body forms a free-form surface (together with the front curved surface of the front support ring), so that the thickness of the layout region does not need to be perfectly matched to the thickness of the lower eyelid region (for example, the thickness distribution of the ring-shaped wearing part gradually increases toward the lower eyelid region), thereby making it possible to make the layout region thinner and effectively improve the oxygen permeability of the layout region, thereby reducing the foreign body sensation when wearing the contact lens.

[0087] Furthermore, the contact lens disclosed in the embodiment of the present invention effectively reduces wrinkles and stress concentration on the carrier substrate by forming at least one through hole occupying a specific area in the C-shaped segment of the lens body (for example, the area of ​​at least one through hole should occupy 1% to 85% of the area surrounded by the outer contour of the C-shaped segment). Furthermore, the contact lens disclosed in the embodiment of the present invention can further improve the oxygen permeability of the contact lens by combining the arrangement of at least one through hole with a free-form surface.

[0088] The above disclosure is merely a preferred embodiment of the present invention, and does not limit the scope of the claims of the present invention. Therefore, all equivalent technical modifications made based on the contents of the specification and accompanying drawings of the present invention shall be included in the scope of the claims of the present invention.
