DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] FIG. 1 is a schematic top view of a contact lens according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view taken along the line AA in FIG. 1. Referring to FIG. 1 and FIG. 2, a contact lens 100 according to an embodiment of the present invention includes a lens body 110 and a pattern 120. The lens body 110 has an optical region 111 and a peripheral region 112, and the peripheral region 112 is arranged to surround the optical region 111. The peripheral region 112 has an adjacent body portion 113 and a first positioning portion 114. The pattern 120 is disposed inside the lens body 110 and located in the peripheral region 112. The first thickness T1 of the first positioning portion 114 is greater than or less than the thickness T of the body portion 113. Specifically, the edge contour of the lens body 110 according to this embodiment is, for example, circular, as shown in FIG. 1. The optical region 111 according to this embodiment is, for example, a portion corresponding to the pupil P of the eyeball, and is, for example, circular, as shown in FIG. 8. The center of the optical region 111, for example, overlaps with the center of the lens body 110, and the optical region 111 has a function of, for example, transmitting light rays to enter the eyeball. The peripheral region 112 in this embodiment is, for example, annular and is formed adjacent to and surrounding the outer periphery of the optical region 111, but the present invention is not limited thereto.

[0015] In one embodiment of the present invention, the first positioning portion 114 is adjacent to the body portion 113, for example, located on the side of the peripheral region 112 away from the optical region 111. In this embodiment, the first positioning portion 114 is in contact with the outer periphery of the peripheral region 112, for example, but the present invention is not limited thereto. In addition, the first positioning portion 114 is shaped like a half moon, for example, as shown in FIG. 1, but the present invention is not limited thereto. In other embodiments, the first positioning portion 114 may have other shapes, for example, an ellipse (not shown). In this embodiment, the body portion 113 is formed adjacent to the optical region 111 and surrounds its outer periphery.

[0016] For example, in one embodiment of the present invention shown in Figures 1 and 2, the first thickness T1 of the first positioning portion 114 is greater than the thickness T of the body portion 113. The thickness of the lens body 110 is basically positively correlated with the weight, that is, the greater the thickness, the heavier the weight. Therefore, when the contact lens 100 is worn on the eyeball, the first positioning portion 114 tends to move downward due to the influence of gravity, for example, due to its heavy weight, and the first positioning portion 114 can be positioned below the optical region 111 (see Figures 1 and 2). That is, in this embodiment, when the contact lens 100 is worn, the first positioning portion 114 can be positioned at an appropriate position on the eyeball, that is, below the pupil. In addition, in one embodiment of the present invention, the relative positions of the first positioning portion 114 and the pattern 120 on the contact lens 100 are fixed, so that the first positioning portion 114 is properly positioned on the eyeball, and when the user wears the contact lens 100, the first positioning portion 114 can stabilize the position of the pattern 120 and ensure an aesthetic appearance.

[0017] In this embodiment, the pattern 120 is disposed inside the lens body 110 and located in the peripheral region 112 (see FIG. 2). In this embodiment, the pattern 120 is, for example, asymmetric, for example, half-moon (symmetrical but asymmetrical up and down) (see FIG. 1), but the present invention is not limited thereto. In this embodiment, the pattern 120 is, for example, disposed on one side of the lens body 110, for example, disposed on half the edge of the lens body 110 (see FIGS. 1 and 2), but the present invention is not limited thereto. In addition, in this embodiment, the pattern 120 is, for example, disposed on the side of the peripheral region 112 away from the optical region 111, i.e., close to the outer periphery of the peripheral region 112, but the present invention is not limited thereto.

[0018] In one embodiment of the present invention, the first thickness T1a of the first positioning portion 114a can be smaller than the thickness T of the body portion 113 (see FIG. 3 and FIG. 4). This also allows the pattern 120 to be properly positioned and ensures aesthetics when worn. Referring to FIG. 3 and FIG. 4, the contact lens 100a in this embodiment is similar to the contact lens 100, but the main difference is that the first thickness T1a of the first positioning portion 114a is smaller than the first thickness T1 of the first positioning portion 114. Specifically, since the first thickness T1a of the first positioning portion 114a is smaller than the thickness T of the body portion 113, when the contact lens 100a is worn on the eyeball, the first positioning portion 114a is light in weight and, for example, tilts upward. As a result, the first positioning portion 114a can be positioned above the optical region 111. That is, in this embodiment, when the contact lens 100a is worn, the first positioning portion 114a can be positioned on the eyeball, i.e., above the pupil. Therefore, when the user wears the contact lens 100a, the pattern 120 can be appropriately positioned by the first positioning portion 114a, and the aesthetic appearance when worn can be ensured.

[0019] The present invention employs a lens body 110 in which the first thickness T1 of the first positioning portion 114 is greater than the thickness T of the main body portion 113, and a lens body 110a in which the first thickness T1a of the first positioning portion 114a is smaller than the thickness T of the main body portion 113. This allows the user to easily position the pattern 120 when wearing the contact lenses 100 and 100a, and ensures a beautiful appearance when worn.

[0020] FIG. 5 is a schematic top view of a contact lens according to another embodiment of the present invention, and FIG. 6 is a schematic cross-sectional view taken along the CC cross-sectional line of FIG. 5. Referring to FIG. 5 and FIG. 6, the peripheral region 112b of the contact lens 100b according to this embodiment further includes a second positioning portion 115, which faces the first positioning portion 114b, does not overlap with the first positioning portion 114b, and is adjacent to the main body portion 113, and its second thickness T2 is smaller than the thickness T of the main body portion 113, and its first thickness T1 is larger than the thickness T of the main body portion 113. Specifically, the first positioning portion 114b and the second positioning portion 115 according to this embodiment are located on opposite sides of the peripheral region 112b, but the present invention is not limited thereto. Also, the second positioning portion 115 according to this embodiment has a shape similar to a half moon shape, as shown in FIG. 5, but is not limited thereto. In other embodiments, the second positioning portion 115 may have other shapes, such as an ellipse (not shown).

[0021] In this embodiment, the first thickness T1 of the first positioning portion 114b is, for example, larger than the thickness T, and the second thickness T2 of the second positioning portion 115 is, for example, smaller than the thickness T. As a result, when the contact lens 100b is worn on the eyeball, the first positioning portion 114b is heavy and therefore tilts downward, for example, due to the influence of gravity. On the other hand, the second positioning portion 115 is light and therefore tilts upward, for example. As a result, the first positioning portion 114b can be positioned below the optical region 111, and the second positioning portion 115 can be positioned above the optical region 111. In this way, in this embodiment, when the user wears the contact lens 100b, the pattern 120 can be appropriately positioned by the first positioning portion 114b and the second positioning portion 115, and the aesthetic appearance when worn can be ensured.

[0022] It is worth mentioning that the pattern 120 of the contact lens 100b is easy to position, and when a user wears the contact lens 100b on both eyes at the same time, the effect of positioning the pattern 120 can be more clearly confirmed. For example, as shown in FIG. 8, when a user wears the contact lens 100b on both eyes at the same time, the patterns 120 of both contact lenses 100b are positioned at the same positions corresponding to, for example, each eyeball, which further improves the aesthetic appearance when worn. Meanwhile, although not shown, the contact lens 100 and the contact lens 100a also have the pattern positioning effect, so that the positioning effect as shown in FIG. 8 can be obtained when a user wears the contact lens 100 on both eyes or when a user wears the contact lens 100 on both eyes.

[0023] 5 and 6 of the embodiment of the present invention, the influence of gravity is more significant because the weight difference between the first positioning portion 114b and the second positioning portion 115 is large. Therefore, the contact lens 100b having the first positioning portion 114b and the second positioning portion 115 can be positioned more reliably, and the positioning of the pattern 120 is also easier.

[0024] In one embodiment of the present invention, the pattern 120 is arranged to overlap, for example, the first positioning portion 114 (see FIG. 1), but the present invention is not limited thereto. In another embodiment, the pattern 120 is arranged to overlap, for example, the second positioning portion 115 (see FIG. 7). The pattern 120 can also overlap, for example, the first positioning portion 114b and extend from the first positioning portion 114b to the second positioning portion 115. It should be noted that the present invention does not necessarily require the pattern 120 to overlap the first positioning portion 114b when overlapping the second positioning portion 115, and does not necessarily require the pattern 120 to extend from the first positioning portion 114b to the second positioning portion 115. In one embodiment, the pattern 120 may be arranged to overlap only the second positioning portion 115 (not shown), or to overlap neither the first positioning portion 114b nor the second positioning portion 115. The present invention does not particularly limit the relative positions of the pattern 120, the first positioning portion 114b, and the second positioning portion 115, and these can be adjusted according to design needs.

[0025] In summary, the present invention uses a lens body having a first positioning part, which allows the user to easily position the pattern when wearing the contact lens, and ensures the aesthetic appearance when worn. Furthermore, if the lens body of the present invention also has a second positioning part, the pattern can be more easily positioned.

[0026] The present invention has been disclosed above using the embodiments, but the present invention is not limited thereto. Those skilled in the art can make some modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is limited by the appended claims. [Explanation of symbols]
