[0027] The following describes the methods of implementing the "contact lens" disclosed in this invention by specific embodiments. Those skilled in the art will be able to understand the merits and effects of the invention from the content disclosed herein. The invention can be implemented or applied by other different specific embodiments. Each detail in this specification can also be modified and altered in equal measure, based on different viewpoints or applications, as long as it does not depart from the spirit of the invention. Furthermore, the drawings of the invention are for brief and schematic purposes only and do not represent actual dimensions. The following embodiments will describe the technical content of the invention in more detail, but the disclosed content does not limit the scope of protection of the invention.

[0028] Throughout this specification, terms such as “first,” “second,” and “third” may be used to describe various components and signals, but it should be understood that these components and 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, depending on the context, include any one or a combination of the relevant enumerated items.

[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, a contact lens 100 (also referred to as a smart contact lens) is disclosed in this embodiment. The contact lens 100 can be worn in the user's eye 200 (e.g., Figure 3) or embedded in the eye 200 (not shown), depending on the design requirements.

[0030] Furthermore, in this embodiment, the contact lens 100 may have a refractive error correction function, and such refractive errors include hyperopia, myopia, astigmatism, presbyopia, or astigmatism-presbyopia. Alternatively, 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 within the lens body 1. The built-in module 10 comprises a front support ring 4, a rear support ring 5 opposite 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 present invention, the built-in module 10 may comprise only the front support ring 4, the rear support ring 5 and the wiring structure 3, depending on the design requirements, and the electronic component 2 may be omitted. Also, the front support ring 4 and the rear support ring 5 may each be considered as supports. Hereinafter, each component of the contact lens 100 of this embodiment will be described in order, and the connection relationships between multiple components will be described as appropriate.

[0032] In this embodiment, the lens body 1 is formed by curing a hydrogel or a silicone hydrogel, and the hydrogel is, for example, p-HEMA, but is not limited thereto. The lens body 1 includes an optical section 11 and a ring-shaped wearing section 12 surrounding the optical section 11, and the optical section 11 may or may not have a refractive error correction function depending on the design requirements. It should be noted that in this embodiment, no components are embedded in the optical section 11, but components may be embedded in the optical section 11 based on design requirements, for example, 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 for the optical section 11, and both the center of the optical section 11 and the center of the ring-shaped wearing section 12 are located on the central axis L. The ring-shaped wearing section 12 is connected to the outer edge of the optical section 11 and is substantially annular. The built-in module 10 is embedded inside the ring-shaped wearing section 12. Moreover, the production method (or the method for manufacturing the contact lens 100) for embedding the built-in module 10 into the ring-shaped wearing section 12 can be adjusted and modified according to design requirements, and the present invention is not limited thereto.

[0034] Furthermore, the built-in module 10 is embedded in the ring-shaped mounting portion 12, and the front support ring 4 and the rear support ring 5 each surround the outside of the optical portion, with the centers of both located on the central axis 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, thereby ensuring that the electronic component 2 and the wiring structure 3 are completely embedded within the ring-shaped mounting portion 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. Furthermore, the side edges of the electronic component 2 and the side edges of the wiring structure 3 are both connected to the ring-shaped mounting portion 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 manufactured from an eye-friendly material, and the eye-friendly material may include a hydrogel (e.g., p-HEMA) or a silicon hydrogel. While it is desirable that the material properties (e.g., oxygen permeability) of the front support ring 4 and the rear support ring 5 be similar to those of the lens body 1, they may be manufactured from a different material depending on the design requirements, and the present invention is not limited thereto.

[0037] As described above, the contact lens 100 disclosed in the embodiments of the present invention achieves high-precision positioning of the wiring structure 3 (and the electronic component 2) during the production process of the contact lens 100 by forming the front support ring 4 and the rear support ring 5, which are made of eye-friendly material, and by clamping and positioning the wiring structure 3 (and the electronic component 2), thereby maintaining high consistency during mass production of the contact lens 100.

[0038] More specifically, when the wiring structure 3 (and the electronic component 2) is placed in a molding die (not shown in the figure), the multiple positioning structures in the molding die contact the front support ring 4 and the rear support ring 5, which accurately position the wiring structure 3 (and the electronic component 2) in a predetermined position. This is advantageous for forming the lens body 1 that covers the built-in module 10 by injection and curing within the molding die. After the contact lens 100 is removed from the molding die, the front support ring 4 and the rear support ring 5, which were in contact with the multiple positioning structures, have a front curved surface 41 and a rear curved surface 51 formed on them, respectively.

[0039] More specifically, the ring-shaped wearing portion 12 has a C-shaped layout region 121 and a lower eyelid region 122 located between both ends of the layout region 121, and the electronic component 2 is embedded within the lower eyelid region 122. When the contact lens 100 is worn on the eye 200, the positions of the lower eyelid region 122 and the electronic component 2 correspond to the relatively less sensitive lower eyelid 201 of the eye 200, thereby effectively reducing the feeling of a foreign object in the user's eye.

[0040] Viewed from a different angle, as shown in Figures 2 to 6, the surface of the lens body 1 includes a rear surface 1b and a front surface 1a located opposite the rear surface 1b. 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 user's eye 200. That is, the numerical 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 preferably do not have any recesses (or holes) formed thereon, but the present invention is not limited thereto.

[0041] Furthermore, the front surface 1a has a visible surface 11a corresponding to the optical section 11, and the front curved surface 41 is aligned with the front surface 1a to jointly form a free-form surface 12a corresponding to the ring-shaped wearing portion 12. Preferably, neither the front curved surface 41 of the front support ring 4 nor the front surface 1a of the lens body 1 has any recesses (or holes), but the present invention is not limited thereto. In other words, neither the outer surface of the contact lens 100 has any recesses (or holes). Moreover, the visible surface 11a has a first curvature related to the optical design necessary to correct refractive errors, or the first curvature of the visible surface 11a can jointly form a non-power structure with the rear surface 1b.

[0042] Furthermore, the first curvature of the visible surface 11a differs from the second curvature of the free-form surface 12a, thereby causing the thickness distribution of the ring-shaped wearing portion 12 to gradually increase toward the electronic component 2 (for example, the lower eyelid region 122), but the present invention is not limited thereto. For example, in other embodiments of the present invention (not shown), the first curvature may be substantially equal to the second curvature, and the thickness of the ring-shaped wearing portion 12 may be substantially equal.

[0043] From a different perspective, the contact lens 100 can have at least one of the electronic components 2 embedded in any one portion of the ring-shaped wearing portion 12 via the front support ring 4 and the rear support ring 5, depending on the design requirements. For example, in another embodiment of the present invention (not shown), by embedding at least one of the electronic components 2 on each of the horizontal sides of the ring-shaped wearing portion 12 via the front support ring 4 and the rear support ring 5, the thickness of the ring-shaped wearing portion 12 is thickest in the horizontal direction of the eye and gradually thins out in the vertical direction of the eye. This setting method allows for the accommodation of at least two sets of the electronic components 2 and reduces the feeling of foreign body when wearing the contact lens 100.

[0044] As described above, in the embodiment of the present invention, the contact lens 100 is such that 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-form surface 12a, eliminating the need for the thickness of the layout region 121 to perfectly match the thickness of the lower eyelid region 122. As a result, the layout region 121 is made thinner, thereby effectively improving the oxygen permeability of the layout region 121 and reducing the feeling of a foreign object when wearing the contact lens 100.

[0045] To further effectively improve the oxygen permeability of the layout region 121 and reduce the feeling of foreign body when wearing the contact lens 100, it is desirable that the contact lens 100 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 portion 12 (and / or the built-in module 10) is located in the region where the electronic component 2 is located (for example, the lower eyelid region 122), and the minimum thickness Tmin of the ring-shaped wearing portion 12 (and / or the built-in module 10) is located in a part of the layout region 121 away from the lower eyelid region 122 (for example, the top of the layout region 121 in Figure 4). In other words, when the contact lens 100 is worn on the eye 200, the part of the ring-shaped wearing portion 12 (and / or the built-in module 10) having the maximum thickness Tmax corresponds to the lower eyelid 201 of the eye 200, and the part of the ring-shaped wearing portion 12 (and / or the built-in module 10) having the minimum thickness Tmin 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 is not limited to the relative positional relationship between the thickness of the contact lens 100 and the user's upper eyelid 201 and lower eyelid 202.

[0047] The wiring structure 3 may exist independently within the built-in module 10 (not shown), or in combination with the electronic component 2, thereby being electrically or physically driven to perform at least one of several functions, such as receiving energy, transmitting wireless signals, performing digital calculations, monitoring sensors, applying pressure, releasing current, projecting images, optical zooming, and storing power, but the present invention is not limited thereto.

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

[0049] In this embodiment, as shown in Figures 1 to 6, the carrier substrate 31 is formed into a predetermined curved structure through room temperature or high temperature pressurization in a press molding die, so that the carrier substrate 31 has a molded curvature different from the second curvature, and it is desirable that the molded curvature approximates the predetermined curvature formed by the rear surface 1b and the rear curved surface 51 (for example, 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) with a thickness of 10 μm to 300 μm, preferably 40 μm to 80 μm, and 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 connecting segment 312 embedded in the lower eyelid region 122, the connecting segment 312 being connected between the two ends of the C-shaped segment 311. The electronic component 2 is attached to the connecting segment 312, and the wiring 32 is formed on the C-shaped segment 311, extends to the connecting segment 312 and is 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 portion 12) fills at least one of the through-holes 3111. It should be noted that, in a top view of the contact lens 100 (along the central axis L), the area of ​​at least one through-hole 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, in combination with the free-form surface 12a, further improves the oxygen permeability of the contact lens 100.

[0053] Furthermore, the carrier substrate 31 may have a plurality of radial cuts 313 formed from its outer edge toward the central axis L, which makes it easier for the carrier substrate 31 to form the molding curvature and further reduces the occurrence of wrinkles and stress concentration in the carrier substrate 31. The ring-shaped wearing portion 12 is filled with the plurality of radial cuts 313, and in this embodiment, the plurality of radial cuts 313 are formed at the boundary between the C-shaped segment 311 and the connecting segment 312, respectively, but the present invention is not limited thereto.

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

[0055] In this embodiment, the wiring 32 is enclosed to form at least one closed circuit, and the plurality of through holes 3111 of the C-shaped segment 311 are located within at least one of the closed circuits of the wiring 32. It should be noted that in this embodiment, the number of at least one closed circuits is described as plurality, and the plurality of through holes 3111 are each 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 is curved, 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 are roughly crescent-shaped). More specifically, each 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, forming both ends of at least one of the through holes 3111.

[0057] Furthermore, both the inner hole edge 3112 and the outer hole edge 3113 are arc-shaped, the radius of the inner hole edge 3112 is smaller than the radius of the outer hole edge 3113, and the centers of the inner hole edge 3112 and the outer hole edge 3113 are located on two different planes perpendicular to the central axis L. In other words, 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] To more clearly define the distribution of the multiple through-holes 3111, in a top view of the contact lens 100, the central axis L is defined as the origin, and the X and Y axes, which intersect the origin and are perpendicular to each other, are defined from the origin. This divides the lens into four quadrants in a counterclockwise direction: the first quadrant Q1, the second quadrant Q2, the third quadrant Q3, and the fourth quadrant Q4.

[0059] In a top view of the contact lens 100, the lower eyelid region 122 is located in the third quadrant Q3 and the fourth quadrant Q4, the Y-axis is approximately the center line of the lower eyelid region 122, and the lower eyelid region 122 corresponds to the central angle σ122 of the origin, preferably in the range of 30 to 180 degrees. Furthermore, the numerical value of the central angle σ122 may be determined according to design requirements, and the present invention is not limited thereto.

[0060] Furthermore, in a top view 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 in multiple parts 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 of these parts 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.

[0062] The plurality of through holes 3111 include at least one first through hole 3111a and at least one second through hole 3111b. In this embodiment, the number of at least one first through hole 3111a and the number of at least one second through hole 3111b are described as multiple, but the present invention is not limited thereto. Each of the plurality of first through holes 3111a is located inside the plurality of second through holes 3111b. That is, the radius of each second through hole 3111b is different from (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 is arc-shaped, its center is located on the central axis L, and the multiple first through holes 3111a are spaced apart from each other. Similarly, each of the second through holes 3111b is arc-shaped, its center is located on the central axis L, and the multiple second through holes 3111b are spaced apart from each other.

[0065] Furthermore, the contact lens 100 can be used in combination with various devices in this embodiment. For example, in other embodiments of the present invention (not shown), the contact lens 100 can be wirelessly connected to any wearable device worn by the user (e.g., a reader attached to glasses or a reader worn around the neck), and the wearable device (or reader) can employ common wireless transmission technology RFID, for example, a bandwidth of 13.56 MHz or 860-960 MHz, and other technologies such as wireless induction power supply and signal transmission to power, sense, or provide signal feedback to the contact lens 100, thereby enabling intelligent monitoring (e.g., collection and warning of intraocular pressure values ​​over all time periods), intelligent treatment (e.g., controlled release of dry eye medication), AR services (e.g., image projection), and other intelligent applications.

[0066] Furthermore, although this embodiment describes how the built-in module 10 sandwiches the wiring structure 3 and the electronic component 2 by the front support ring 4 and the rear support ring 5, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the front support ring 4 and the rear support ring 5 may each be a plurality of supports arranged in an annular shape. That is, a portion of the front support ring 4 (or the rear support ring 5) can be removed to form a plurality of supports spaced apart from each other.

[0067] More specifically, the plurality of supports are distributed outside the optical unit 11, each support has a curved surface and a carrier surface, the curved surface of each support is aligned with either the front surface 1a or the rear surface 1b of the lens body 1, and the wiring structure 3 (and the electronic components 2) are coupled to the carrier surfaces of the plurality of supports.

[0069] In this embodiment, each of the through holes 3111 is elongated and has a shape of substantially 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 multiple through-holes 3111 distributed in the first quadrant Q1 and the second quadrant Q2 can be larger than the area of ​​the multiple 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. Each of the plurality of first through holes 3111a is located inside the plurality of second through holes 3111b.

[0072] In this embodiment, each of the first through holes 3111a is arc-shaped, its center is located on the central axis L, and the multiple first through holes 3111a are spaced apart from each other.

[0075] Furthermore, the electronic component 2 and the wiring structure 3 are coupled to the rear carrier surface 42 of the front support ring 4 so that the electronic component 2 and the wiring structure 3 are completely embedded within the ring-shaped mounting portion 12 (for example, the built-in module 10 does not come into contact with the rear surface 1b and is positioned at a distance). In other words, 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 portion 12 without any gaps.

[0076] Furthermore, 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 the same as the example shown in Figures 1 and 2 of the first embodiment, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the structure of the carrier substrate 31 may be the same as the structure shown in Figures 10 and 11 of the second embodiment, depending on the design requirements, or the wiring structure 2 may include only the wiring 32.

[0077] Furthermore, in this embodiment, the built-in module 10 is described as connecting the wiring structure 3 and the electronic component 2 by the front support ring 4, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the front support ring 4 may be a plurality of supports arranged in an annular shape, that is, the front support ring 4 can be partially removed to form a plurality of supports arranged at intervals from one another.

[0078] More specifically, the plurality of supports are distributed outside the optical unit 11, and each support has a curved surface and a carrier surface, the curved surface of each support is aligned with the front surface 1a of the lens body 1, and the wiring structure 3 (and the electronic components 2) are coupled to the carrier surfaces of the plurality of supports.

[0079] [Fourth Embodiment] Please refer to the fourth embodiment of the present invention shown in Figures 16 to 18.

[0080] In this embodiment, the built-in module 10 does not include the front support ring 4 described in the first embodiment, and the front surface 1a has a visible surface 11a corresponding to the optical unit 11 and a free-form surface 12a corresponding to the ring-shaped wearing portion 12.

[0081] Furthermore, 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 within the ring-shaped mounting portion 12 (for example, the built-in module 10 does not come into contact with the front surface 1a and is positioned at a distance). In other words, 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 portion 12 without any gaps.

[0082] Furthermore, 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 the same as the example shown in Figures 1 and 2 of the first embodiment, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the structure of the carrier substrate 31 may be the same as the structure shown in Figures 10 and 11 of the second embodiment, depending on the design requirements, or the wiring structure 2 may include only the wiring 32.

[0083] Furthermore, in this embodiment, the built-in module 10 is described as sandwiching the wiring structure 3 and the electronic component 2 by the rear support ring 5, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the rear support ring 5 may be a plurality of supports arranged in an annular shape, that is, the rear support ring 5 can be partially removed to form a plurality of supports arranged at intervals from one another.

[0084] More specifically, the plurality of supports are distributed outside the optical unit 11, and each support has a curved surface and a carrier surface, the curved surface of each support is aligned with the rear surface 1b of the lens body 1, and the wiring structure 3 (and the electronic components 2) are coupled to the carrier surfaces of the plurality of supports.

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

[0086] Furthermore, in the contact lens disclosed in the embodiment of the present invention, the front surface of the lens body (and in cooperation with the front curved surface of the front support ring) forms a free-form surface, so that the thickness of the layout region does not need to perfectly match the thickness of the lower eyelid region (for example, the thickness distribution of the ring-shaped wearing portion gradually increases toward the lower eyelid region), thereby enabling a thinner layout region, effectively improving the oxygen permeability of the layout region, and reducing the feeling of a foreign body when wearing the contact lens.

[0087] Furthermore, the contact lens disclosed in the embodiments of the present invention effectively reduces wrinkles and stress concentration in 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 of the through-holes must occupy 1% to 85% of the area enclosed by the outer contour of the C-shaped segment). Furthermore, the contact lens disclosed in the embodiments of the present invention can further improve the oxygen permeability of the contact lens by combining the arrangement of at least one of the through-holes with a free-form surface.

[0088] The information disclosed above represents only preferred embodiments of the present invention and does not limit the scope of the claims. Therefore, all equivalent technical modifications made based on the specifications and accompanying drawings of the present invention are included within the scope of the claims.
