Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification. This invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this invention. Furthermore, the accompanying drawings of this invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention.
[0037] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or features, these components or features should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one feature from another. Furthermore, the term "or" as used in this document should, as appropriate, include any combination of one or more related items listed.
[0038] [Example 1]
[0039] Please refer to Figures 1 to 7, which illustrate Embodiment 1 of the present invention. This embodiment discloses a contact lens 100 having a spherical front surface 100-1 and a spherical rear surface 100-2 for wearing on the eye E. That is, any contact lens with a non-spherical surface (e.g., an astigmatic contact lens) is not considered part of the contact lens 100 described in this embodiment.
[0040] In this embodiment, the contact lens 100 is equivalent to a self-aligning contact lens; that is, when the contact lens 100 is worn on the eye E, the contact lens 100 is configured by its structure to be rotated to a preset position via blinking of the upper eyelid E1 (e.g., within 10 minutes of blinking).
[0041] As shown in Figure 1, the contact lens 100 can be made of the same material. Specifically, the contact lens 100 can be made of hydrogel, silicone hydrogel, silicone elastomer, or rigid gap-permeable (RGP) material, and the hydrogel may be, for example, poly(2-hydroxyethyl methacrylate) (p-HEMA), but the invention is not limited thereto. For example, in other embodiments not shown in this invention, the contact lens 100 may be made of at least two of the aforementioned materials, or at least one electronic component may be embedded therein, depending on actual needs.
[0042] Furthermore, based on the functions provided by each part of the contact lens 100, the contact lens 100 has (or is divided into) an optical part 1 and a wearing part 2 that surrounds the optical part 1 in a ring shape. The optical part 1 is used for viewing by the eye E (e.g., Figures 5 to 7), while the wearing part 2 is used for wearing on the eye E. It should be noted that the optical part 1 can provide the function of correcting refractive errors through the spherical design of the front surface 100-1 and the rear surface 100-2. The refractive errors include hyperopia, myopia, or presbyopia, but do not include astigmatism; or, the contact lens 100 may not have a corrective function depending on actual needs.
[0043] Furthermore, as shown in Figures 2 to 4, the outer diameter of the contact lens 100 is between 13.8 mm and 15.2 mm, and the outer diameter of the optical part 1 is between 6 mm and 8 mm. Moreover, the contact lens 100 defines a central axis C passing through its center (e.g., the center of the optical part 1) and a first reference surface P1 and a second reference surface P2 intersecting each other perpendicularly at the central axis C. In this embodiment, the contact lens 100 is arranged in a mirror-symmetric configuration with respect to the second reference surface P2, but the present invention is not limited thereto.
[0044] It should be further noted that when the contact lens 100 is worn on the eye E and located in the preset position, the first reference surface P1 of the contact lens 100 is generally parallel to a horizontal plane (or, the first reference surface P1 is generally located between the upper eyelid E1 and the lower eyelid E2 as shown in Figures 6 and 7), and the first reference surface P1 of the contact lens 100 is generally parallel to a vertical plane, but the present invention is not limited thereto.
[0045] In other words, in a top view (e.g., Figure 2) of the contact lens 100 along the central axis C, the central axis C can be considered as the origin, and the contact lens 100 can be divided by the first reference surface P1 and the second reference surface P2 into a first quadrant Q1, a second quadrant Q2, a third quadrant Q3, and a fourth quadrant Q4 distributed in a counterclockwise direction. The first quadrant Q1 and the second quadrant Q2 are located above the first reference surface P1, while the third quadrant Q3 and the fourth quadrant Q4 are located below the first reference surface P1.
[0046] Furthermore, based on the thickness of each part of the contact lens 100, the contact lens 100 has (or is divided into) an arc-shaped weighting section 3, a gradient balance section 4, a regular section 5, and an edge section 6. The gradient balance section 4 connects the arc-shaped weighting section 3 and the regular section 5, and the edge section 6 is annular and surrounds the arc-shaped weighting section 3, the gradient balance section 4, and the regular section 5.
[0047] The arc-shaped weight section 3 is located on the lower side of the first reference surface P1 (e.g., the arc-shaped weight section 3 is located in the third quadrant Q3 and the fourth quadrant Q4), and the arc-shaped weight section 3 is arranged along the outer contour of the contact lens 100 (or the edge section 6). In this embodiment, the arc-shaped weight section 3 is generally U-shaped or C-shaped, and it is located in the wearing part 2 and spaced apart from the optical part 1.
[0048] Furthermore, in the top view of the contact lens 100 (e.g., Figures 2 and 3), the inner edge 31 of the arc-shaped weight section 3 is generally parallel to the lower edge of the optical part 1 located on the lower side of the first reference surface P1, and the outer edge 32 of the arc-shaped weight section 3 is generally parallel to the outer contour of the contact lens 100 (or the edge section 6), and the inner edge 31 and the outer edge 32 of the arc-shaped weight section 3 are generally equally spaced, but the present invention is not limited thereto.
[0049] Furthermore, the two ends 33 of the arc-shaped counterweight section 3 are located on opposite sides of the second reference surface P2, and the two ends 33 of the arc-shaped counterweight section 3 are adjacent to and spaced apart from the first reference surface P1. That is, each end 33 of the arc-shaped counterweight section 3 is closer to the first reference surface P1 than to the second reference surface P2.
[0050] In the top view of the contact lens 100, the arc-shaped weight section 3 has a first central angle σ1 between 120 and 170 degrees relative to the central axis C, and the arrangement distance D31 between the inner edge 31 of the arc-shaped weight section 3 and the central axis C is preferably between 55% and 75% of the radius R of the contact lens 100. In this embodiment, the first central angle σ1 may be defined by the two ends 33 and the central axis C, and the first central angle σ1 is preferably between 155 and 165 degrees, but the invention is not limited thereto. Furthermore, the arc-shaped weight section 3 has a first thickness T1 between 0.25 mm and 0.4 mm, which is the maximum thickness value of the contact lens 100.
[0051] The gradual balance section 4 is formed by extending from the arc-shaped counterweight section 3 toward the first reference surface P1, and the gradual balance section 4 has two correction ends 41 located on the upper side of the first reference surface P1. That is, the gradual balance section 4 is also generally U-shaped or C-shaped, with the two correction ends 41 located in the first quadrant Q1 and the second quadrant Q2 respectively and adjacent to the end 33 of the arc-shaped counterweight section 3, while the portion of the gradual balance section 4 other than the two correction ends 41 is located in the third quadrant Q3 and the fourth quadrant Q4.
[0052] In the top view of the contact lens 100, the sum of the areas of the arc-shaped weight section 3 and the gradient balance section 4 accounts for 30% to 70% (e.g., preferably 40% to 60%) of the total area of the contact lens 100, and the area of the arc-shaped weight section 3 can be 30% to 80% of the sum of the areas of the arc-shaped weight section 3 and the gradient balance section 4, but the present invention is not limited thereto.
[0053] Furthermore, in the top view of the contact lens 100, the area of the two correction ends 41 generally occupies 3% to 15% of the area of the gradient balance section 4. From another perspective, in the top view of the contact lens 100, the gradient balance section 4 has a second central angle σ2 relative to the central axis C, between 170 degrees and 240 degrees. Therefore, each correction end 41 and its adjacent end 33 can define a third central angle σ3 relative to the central axis C. In this embodiment, the second central angle σ2 can be defined jointly by the two correction ends 41 and the central axis C, and the second central angle σ2 is preferably between 190 degrees and 210 degrees, but the invention is not limited thereto.
[0054] Furthermore, as shown in Figures 2 to 4, the gradual balance section 4 has a second thickness T2 that is less than the first thickness T1, and the second thickness T2 decreases in the direction away from the arc-shaped counterweight section 3. In this embodiment, the second thickness T2 decreases by a preset thickness for each degree of the third central angle σ3 passed from each end 33 toward the adjacent correction end 41, and the preset thickness is between 3 micrometers and 7 micrometers.
[0055] It should be further noted that, in the top view of the contact lens 100, the gradient balance section 4 overlaps 5% to 45% of the area of the optical part 1 to facilitate the overall weight distribution structure of the contact lens 100. In other words, any contact lens with a uniformly thick optical part is different from the contact lens 100 referred to in this embodiment. Furthermore, in this embodiment, the gradient balance section 4 preferably overlaps 25% to 35% of the area of the optical part 1, and the prism diopter of the optical part 1 is less than 1Δ, but the present invention is not limited thereto.
[0056] In other words, the optical section 1 is composed of the conventional section 5 and the gradient balance section 4, and the central axis C passes through the conventional section 5. The conventional section 5 has a third thickness T3, which is less than the second thickness T2 and can be between 0.09 mm and 0.24 mm. The third thickness T3 of the conventional section 5 is approximately the same as the thickness of a typical contact lens. That is, the optical section 1 has the first thickness T1 on the upper side of the first reference surface P1, and the optical section 1 at least partially has the second thickness T2 on the lower side of the first reference surface P1.
[0057] With the aforementioned thickness configuration, the overall volume distribution of the contact lens 100 can meet the following conditions: the volume of the lower half of the contact lens 100 located on the lower side of the first reference surface P1 can be 150% to 200% of the volume of the upper half of the contact lens 100 located on the upper side of the first reference surface P1.
[0058] As described above, as shown in Figures 1 to 7, when the contact lens 100 provided in this embodiment is worn on the eye E and an angular offset occurs (e.g., Figure 5), the contact lens 100 can be configured to allow the arc-shaped weight section 3 to rotate toward the lower eyelid E2, and the two correction ends 41 of the gradual balance section 4 can be pushed by the blinking of the upper eyelid E1 (e.g., Figure 6), so that the contact lens 100 is maintained more accurately in the preset position (e.g., the actual position of the contact lens 100 differs from the orientation of the preset position by less than 5 degrees), so that at least a portion of the arc-shaped weight section 3 is located within the lower eyelid E2.
[0059] To put it another way, if the two correction ends 41 of the gradient balance section 4 are designed to be located on the lower side of the first reference surface P1 (e.g., the second central angle σ2 is less than 180 degrees), then the blinking of the upper eyelid E1 will make it difficult to push the two correction ends 41, and thus the contact lens 100 will not be able to fall accurately at the predetermined position.
[0060] [Example 2]
[0061] Please refer to Figures 8 and 9, which illustrate Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated. The main differences between this embodiment and Embodiment One are explained below:
[0062] This embodiment discloses a colored contact lens M, which includes a lens body 100a and a pattern layer 200a formed on the lens body 100a. The structure of the lens body 100a referred to in this embodiment is equivalent to the structure of the contact lens described in Embodiment 1, and therefore will not be repeated below.
[0063] Furthermore, the pattern layer 200a is formed on the eyeglass body 100a and surrounds the optical part 1 (that is, the pattern layer 200a is located on the wearing part 2), and the pattern layer 200a is asymmetrical with respect to the central axis C. In this embodiment, the pattern layer 200a includes multiple protective layers and multiple ink layers, and the multiple ink layers may be stacked on top of each other to jointly form an asymmetrical shape with respect to the central axis C according to actual needs.
[0064] Therefore, when the colored contact lens M provided in this embodiment is worn on the eye E and an angular displacement occurs, the colored contact lens M can be maintained more accurately at the preset position through the structural configuration of the eyeglass body 100a, thereby ensuring that the pattern layer 200a is in the correct orientation. In other words, any colored contact lens employing a symmetrical pattern layer is not the colored contact lens M referred to in this embodiment.
[0065] [Technical Effects of the Embodiments of the Invention]
[0066] In summary, the makeup contact lens and the contact lens disclosed in the embodiments of the present invention, when worn on the eye and experiencing angular displacement, both the contact lens and the makeup contact lens can, through their structural configuration (e.g., the structural configuration of the arc-shaped weighting section and the gradient balance section, and the overlap of the gradient balance section with a portion of the optical part), facilitate the rotation of the arc-shaped weighting section toward the lower eyelid, and the two correction ends of the gradient balance section can be pushed by the blinking of the upper eyelid, thereby ensuring that both the contact lens and the makeup contact lens are maintained more accurately at the preset position.
[0067] 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.
