[0044] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, 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 should, as appropriate, include any combination of one or more of the related listed items.

[0045] [Example 1]

[0046] Please see Figures 1 to 9 As shown, this is an embodiment of the present invention. Figures 1 to 6 As shown, this embodiment discloses a contact lens 100 (or smart contact lens). The contact lens 100 can be worn on the user's eye 200 according to design requirements (e.g.: Figure 3 Alternatively, it can be implanted within the eye 200 (not shown in the figure).

[0047] Furthermore, in this embodiment, the contact lens 100 may have the function of correcting refractive errors, and the refractive errors include hyperopia, myopia, astigmatism, presbyopia, or astigmatism-presbyopia; or, the contact lens 100 may be a makeup lens without corrective function.

[0048] In this embodiment, the contact lens 100 includes a lens body 1 and an embedded module 10 embedded within the lens body 1. The embedded 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 circuit structure 3 sandwiched between the front support ring 4 and the rear support ring 5 and electrically coupled to the electronic component 2. However, the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the embedded module 10 may, depending on design requirements, include only the front support ring 4, the rear support ring 5, and the circuit structure 3, omitting the electronic component 2. Furthermore, the front support ring 4 and the rear support ring 5 may each be considered as a support body. The various components of the contact lens 100 of this embodiment will be described sequentially below, and the connection relationships between the multiple components will be introduced as appropriate.

[0049] In this embodiment, the eyeglass body 1 is formed by curing with hydrogel or silicone hydrogel, and the hydrogel is, for example, p-HEMA, but is not limited thereto. The eyeglass body 1 includes an optical section 11 and a ring-shaped wearing section 12 surrounding the optical section 11. The optical section 11 may or may not have the function of correcting the refractive error, depending on design requirements. It should be noted that although no components are embedded in the optical section 11 in this embodiment, components may be embedded within it according to design requirements (e.g., the contact lens 100 is used in a digital zoom device), and is not limited to the above description of this embodiment.

[0050] Furthermore, the optical part 11 defines a central axis L, and the center of the optical part 11 and the center of the annular wearing part 12 both reside on the central axis L. The annular wearing part 12 is connected to the outer edge of the optical part 11 and is generally annular in shape, and the embedded module 10 is embedded inside the annular wearing part 12. Moreover, the manufacturing method (or the method of manufacturing the contact lens 100) for embedding the embedded module 10 in the annular wearing part 12 can be adjusted and varied according to design requirements, and this invention is not limited thereto.

[0051] Furthermore, the embedded module 10 is embedded in the annular wearing part 12, and the front support ring 4 and the rear support ring 5 each surround the outer side of the optical part, with their centers both located on the central axis L. The front support ring 4 has a front curved surface 41 and a rear bearing surface 42, and the rear support ring 5 has a rear curved surface 51 and a front bearing surface 52 facing the rear bearing surface 41.

[0052] More specifically, the electronic component 2 and the circuit structure 3 are both clamped and positioned between the rear bearing surface 42 of the front support ring 4 and the front bearing surface 52 of the rear support ring 5, so that the electronic component 2 and the circuit structure 3 are completely embedded within the annular wearing portion 12. In this embodiment, at least one of the front support ring 4 and the rear support ring 5 (along the central axis L) covers the entire electronic component 2 and the entire circuit structure 3, but is not limited thereto. Furthermore, the side edges of the electronic component 2 and the side edges of the circuit structure 3 are connected to the annular wearing portion 12 (e.g., the lower eyelid area 122 described below) without gaps.

[0053] Furthermore, in this embodiment, the front support ring 4 and the rear support ring 5 are each made of an eye-friendly material, which may include hydrogel (e.g., p-HEMA) or silicone hydrogel. Preferably, the materials used for the front support ring 4 and the rear support ring 5 have properties (e.g., oxygen permeability) similar to those of the eyeglass body 1. However, the front support ring 4 and the rear support ring 5 may also be made of materials different from those of the eyeglass body 1, depending on design requirements; this invention does not impose any limitations on this.

[0054] As described above, the contact lens 100 disclosed in the embodiments of the present invention uses a front support ring 4 and a rear support ring 5 made of the eye-friendly material to clamp and position the circuit structure 3 (and the electronic component 2), so that the contact lens 100 can achieve high-precision positioning of the circuit structure 3 (and the electronic component 2) during the manufacturing process, thereby ensuring that the contact lens 100 maintains a high degree of consistency during mass production.

[0055] More specifically, when the circuit structure 3 (and the electronic component 2) are disposed within a molding die (not shown in the figure), multiple positioning structures of the molding die abut against the front support ring 4 and the rear support ring 5 to precisely position the circuit structure 3 (and the electronic component 2) to a predetermined position, thereby facilitating the pouring and curing within the molding die to form the eyeglass body 1 covering the embedded module 10. After the contact lens 100 is removed from the molding die, the front support ring 4 and the rear support ring 5, which previously abutted against the multiple positioning structures, respectively form the front curved surface 41 and the rear curved surface 51.

[0056] More specifically, the annular wearing portion 12 has a C-shaped layout area 121 and a lower eyelid area 122 located between the two ends of the layout area 121, and the electronic component 2 is embedded within the lower eyelid area 122. When the contact lens 100 is worn on the eye 200, the lower eyelid area 122 and the electronic component 2 are positioned within the lower eyelid 201, where the eye 200 is less sensitive, thereby effectively reducing the user's foreign body sensation.

[0057] To put it another way, such as Figures 2 to 6 As shown, the surface of the eyeglass body 1 includes a rear surface 1b and a front surface 1a located on the opposite side of the rear surface 1b. The rear curved surface 51 of the rear support ring 5 is flush with the rear surface 1b of the eyeglass body 1 to jointly form a preset curvature suitable for wearing on the user's eyes 200; that is, the value of the preset curvature is only related to the eyes 200. Furthermore, it is preferable that the rear curved surface 51 of the rear support ring 5 and the rear surface 1b of the eyeglass body 1 do not form any grooves (or holes), but the present invention is not limited thereto.

[0058] Furthermore, the front surface 1a has a visible surface 11a corresponding to the optical part 11, and the front curved surface 41 is flush with the front surface 1a to jointly form a free-form surface 12a corresponding to the annular wearing part 12; wherein, preferably, the front curved surface 41 of the front support ring 4 and the front surface 1a of the eyeglass body 1 do not have any grooves (or holes), but the present invention is not limited thereto. That is, the outer surface of the contact lens 100 does not have any grooves (or holes). Furthermore, the visible surface 11a has a first curvature, which is related to the optical design required to correct the refractive error; or, the first curvature of the visible surface 11a may also form a non-prescription structure together with the rear surface 1b.

[0059] Furthermore, the first curvature of the visible surface 11a differs from a second curvature of the freeform surface 12a, so that the thickness distribution of the annular wearing portion 12 gradually increases toward the electronic component 2 (e.g., the lower eyelid region 122), but the invention is not limited thereto. For example, in other embodiments not shown in the invention, the first curvature may be approximately equal to the second curvature, and the thickness of the annular wearing portion 12 may be approximately equal.

[0060] In other words, the contact lens 100 can embed at least one electronic component 2 at any location of the annular wearing portion 12 via the front support ring 4 and the rear support ring 5, according to design requirements. For example, in other embodiments not shown in this invention, at least one electronic component 2 is embedded on each of the horizontal sides of the annular wearing portion 12 via the front support ring 4 and the rear support ring 5, so that the thickness of the annular wearing portion 12 is thickest at the horizontal position of the eye and gradually thins towards the eye in a plumb line. Accordingly, this arrangement can accommodate at least two sets of electronic components 2 and can reduce the foreign body sensation when wearing the contact lens 100.

[0061] As described above, the contact lens 100 disclosed in the embodiments of the present invention forms the free-form surface 12a together with the front surface 1a of the lens body 1 and the front curved surface 41 of the front support ring 4, so that the thickness of the layout area 121 does not have to completely accommodate the thickness of the lower eyelid area 122, thereby achieving the thinning of the layout area 121, thereby effectively improving the oxygen permeability of the layout area 121 and reducing the foreign body sensation when wearing the contact lens 100.

[0062] In order to more effectively improve the oxygen permeability of the layout area 121 and reduce the foreign body sensation of the contact lens 100, the contact lens 100 is preferably configured by adjusting the second curvature of the freeform surface 12a to have at least one of the features described below, but the present invention is not limited thereto.

[0063] The maximum thickness Tmax of the annular wearing portion 12 (and / or the embedded module 10) falls within the region where the electronic component 2 is located (e.g., the lower eyelid region 122), and the minimum thickness Tmin of the annular wearing portion 12 (and / or the embedded module 10) falls within a portion of the layout area 121 that is far from the lower eyelid region 122 (e.g., Figure 4 (The top of the layout area 121 in the image). That is, when the contact lens 100 is worn on the eye 200, the portion of the annular wearing part 12 (and / or the embedded module 10) with the maximum thickness Tmax is located within the lower eyelid 201 of the eye 200, and the portion of the annular wearing part 12 (and / or the embedded module 10) with the minimum thickness Tmin is located within the upper eyelid 202 of the eye 200. Although the maximum thickness Tmax and the minimum thickness Tmin correspond to the user's lower eyelid 201 and upper eyelid 202 in this embodiment, the present invention does not limit the relative positional relationship between the thickness of the contact lens 100 and the user's eyelids 201 and 202.

[0064] The circuit structure 3 can exist independently within the embedded module 10 (not shown in the figure) or be combined with the electronic component 2, and can be driven by electricity or by physical means to realize at least one of multiple functions such as energy reception, wireless signal transmission, digital calculation, sensing and monitoring, pressure application, current release, image projection, optical zoom and power storage, but the present invention is not limited thereto.

[0065] It should be noted that, as Figures 1 to 6 As shown, in this embodiment, the circuit structure 3 includes a carrier board 31 and a circuit 32 (e.g., a metal circuit) formed on the carrier board 31, and the circuit 32 is connected to the electronic component 2 and electrically coupled to each other, but the present invention is not limited thereto. For example, such as Figures 7 to 9 As shown, the circuit structure 3 may include a circuit 32 connected to the electronic component 2, and the circuit 32 is not formed on any carrier plate; that is, the embedded module 10 provides the pre-position of the circuit 32 through the front support ring 4 and the rear support ring 5 to prevent the circuit 32 from moving or deforming when forming the eyeglass body 1.

[0066] In this embodiment, as Figures 1 to 6As shown, the carrier plate 31 can be shaped into a preset curved structure by applying pressure at room temperature or high temperature using a pressing mold, so that the carrier plate 31 has a fixed curvature different from the second curvature, and the fixed curvature is preferably close to the preset curvature formed by the rear surface 1b and the rear curved surface 51 (e.g., the fixed curvature is 100% to 110% of the preset curvature), but the present invention is not limited to the above.

[0067] In this embodiment, the carrier board 31 is described as a flexible printed circuit board (FPCB) with a thickness between 10 micrometers and 300 micrometers, and the thickness of the carrier board 31 is preferably between 40 micrometers and 80 micrometers. The polymer material of the carrier board 31 may include polyimide (PI), liquid-crystal polymer (LCP), polyethylene terephthalate (PET), or polyethylene naphthalate (PEN), but is not limited to the above.

[0068] More specifically, the carrier plate 31 has a C-shaped segment 311 embedded in the layout area 121 and a connecting segment 312 embedded in the lower eyelid area 122, and the connecting segment 312 is connected between the two end edges of the C-shaped segment 311. The electronic component 2 may be mounted on the connecting segment 312, and the circuit 32 is formed in the C-shaped segment 311 and extends to the connecting segment 312 to connect to the electronic component 2.

[0069] Furthermore, given that the carrier plate 31 is prone to wrinkling or stress concentration during the pressure forming process, the C-shaped segment 311 is formed with at least one through hole 3111, and the lens body 1 (e.g., the annular wearing part 12) fills at least one through hole 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 through hole 3111 needs to occupy 1% to 85% (preferably 10% to 40%) of the area surrounded by the outer contour of the C-shaped segment 311, thereby effectively reducing the occurrence of wrinkling or stress concentration in the carrier plate 31 and further improving the oxygen permeability of the contact lens 100 by cooperating with the freeform surface 12a.

[0070] Furthermore, the carrier plate 31 may also have multiple radial cuts 313 formed from its outer edge toward the central axis L, to facilitate the formation of the shaping curvature of the carrier plate 31 and thereby further reduce the occurrence of wrinkles or stress concentration in the carrier plate 31. The annular wearing portion 12 is filled with the multiple radial cuts 313, and in this embodiment, the multiple radial cuts 313 are respectively formed at the junction of the C-shaped segment 311 and the connecting segment 312, but the present invention is not limited thereto.

[0071] Furthermore, in the top view of the contact lens 100, the area of ​​at least one through hole 3111 occupies 1% to 75% of the area of ​​the annular wearing portion 12. While the number of through holes 3111 formed in the C-shaped segment 311 is described as multiple in this embodiment, the invention is not limited thereto. For example, in other embodiments not shown in this invention, the C-shaped segment 311 of the carrier plate 31 may not have any through holes 3111 formed therein.

[0072] In this embodiment, the line 32 surrounds and forms at least one closed loop, and the plurality of through holes 3111 of the C-shaped segment 311 are located within at least one closed loop of the line 32. It should be noted that the number of at least one closed loop is described as multiple in this embodiment, and the plurality of through holes 3111 are respectively located within the plurality of closed loops of the line 32, but the present invention is not limited thereto.

[0073] Each of the through holes 3111 is curved, and the width of any one of the through holes 3111 gradually increases from its two ends toward the center (e.g., the through hole 3111 is approximately crescent-shaped in this embodiment). More specifically, each of the through holes 3111 has an inner edge 3112 and an outer edge 3113, and the two ends of the inner edge 3112 are respectively connected to the two ends of the outer edge 3113 to respectively form the two ends of at least one through hole 3111.

[0074] In this embodiment, both the inner hole edge 3112 and the outer hole edge 3113 are arc-shaped, and the radius of the inner hole edge 3112 is smaller than the radius of the outer hole edge 3113. The center of the inner hole edge 3112 and the center of the outer hole edge 3113 are located on two different planes perpendicular to the central axis L. That is to say, each through hole 3111 in this embodiment is configured along the shaped curvature of the carrier plate 31, rather than being planar.

[0075] To more clearly define the distribution of the multiple through holes 3111, in the top view of the contact lens 100, the central axis L is defined as an origin, and based on the origin, an X-axis and a Y-axis are defined that intersect the origin and are perpendicular to each other, thereby dividing a first quadrant Q1, a second quadrant Q2, a third quadrant Q3 and a fourth quadrant Q4 in a counterclockwise direction.

[0076] In the top view of the contact lens 100, the lower eyelid area 122 is located in the third quadrant Q3 and the fourth quadrant Q4, and the Y-axis is approximately the midline of the lower eyelid area 122.

[0105] [Technical Effects of the Embodiments of the Invention]

[0106] In summary, the contact lens disclosed in the embodiments of the present invention positions the circuit structure (and the electronic components) by planning and forming at least one of the front support ring, the rear support ring, and a plurality of support bodies made of the eye-friendly material. This facilitates high-precision positioning of the circuit structure (and the electronic components) during the manufacturing process of the contact lens, thereby ensuring high consistency of the contact lens during mass production.

[0107] Furthermore, the contact lens disclosed in the embodiments of the present invention has a free-form surface formed on the front surface of the lens body (and the front curved surface of the front support ring), so that the thickness of the layout area does not have to completely accommodate the thickness of the lower eyelid area (e.g., the thickness distribution of the annular wearing part gradually increases towards the lower eyelid area), thereby achieving a thinner layout area, thereby effectively improving the oxygen permeability of the layout area and reducing the foreign body sensation when wearing the contact lens.

[0108] Furthermore, the contact lens disclosed in this embodiment of the invention has at least one through-hole occupying a specific area formed in the C-shaped segment of the lens body (e.g., the area of ​​at least one through-hole needs to occupy 1% to 85% of the area surrounded by the outer contour of the C-shaped segment), thereby effectively reducing the occurrence of wrinkles or stress concentration in the carrier plate. In addition, the contact lens disclosed in this embodiment of the invention can further improve the oxygen permeability of the contact lens by combining the configuration of at least one through-hole with the freeform surface.

[0109] The content disclosed above is only a preferred and feasible embodiment of the present invention, and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included within the patent scope of the present invention.
