[0022] Figure 1 This is a top view schematic diagram of a corneal contact lens according to an embodiment of the present invention. Figure 2 For along Figure 1 A cross-sectional diagram of section line AA in the diagram. Please refer to... Figure 1 and Figure 2An embodiment of the present invention provides a corneal contact lens 100, comprising a lens body 110 and a pattern 120. The lens body 110 has an optical region 111 and a peripheral region 112, the peripheral region 112 surrounding the optical region 111, and having adjacent body portions 113 and first positioning portions 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 in this embodiment is, for example, circular. Figure 1 As shown. In this embodiment, the optical region 111 corresponds, for example, to the pupil P of the eyeball, such as... Figure 8 As shown, the optical region 111 is, for example, circular. The center of the optical region 111 overlaps with the center of the lens body 110, for example, and the optical region 111 is adapted to allow light to pass through and enter the eyeball. The peripheral region 112 in this embodiment is, for example, annular, and the peripheral region 112 is adjacent to and surrounds the optical region 111, but the present invention is not limited thereto.

[0023] In one embodiment of this utility model, the first positioning part 114 is adjacent to the main body part 113, and the first positioning part 114 is, for example, located on the side of the peripheral area 112 away from the optical area 111. In this embodiment, the first positioning part 114 is, for example, connected to the outer circumference of the peripheral area 112, but this utility model does not specifically limit this. In this embodiment, the first positioning part 114 is, for example, similar to a crescent shape, such as... Figure 1 As shown, but the present invention is not limited thereto. In another embodiment, the first positioning part 114 may be of other shapes, such as an ellipse (not shown). In this embodiment, the body part 113 is adjacent to and surrounds the optical region 111, for example.

[0024] For example, this utility model is as follows: Figure 1 and Figure 2 In one embodiment shown, the first thickness T1 of the first positioning portion 114 is greater than the thickness T of the body portion 113. Since the thickness of the lens body 110 is substantially positively correlated with its weight (i.e., the greater the thickness, the greater the weight), when the contact lens 100 is worn on the eyeball, the first positioning portion 114, due to its greater weight, will tend to move downwards, for example, due to gravity, so that the first positioning portion 114 can be located below the optical zone 111. Figure 1 and Figure 2As shown. In other words, in this embodiment, when wearing the corneal contact lens 100, the first positioning part 114 can be positioned on the eyeball, that is, it can be positioned below the pupil. Furthermore, in one embodiment of this utility model, since the relative position of the first positioning part 114 and the pattern 120 on the corneal contact lens 100 is fixed, and the first positioning part 114 can be positioned on the eyeball, when the user wears the corneal contact lens 100, the first positioning part 114 can position the pattern 120 to ensure aesthetics during wear.

[0025] In this embodiment, the pattern 120 is disposed inside the lens body 110 and located in the peripheral area 112, such as... Figure 2 As shown. In this embodiment, the pattern 120 is, for example, an asymmetrical shape, such as a crescent shape (symmetrical left and right, asymmetrical top and bottom), as shown. Figure 1 As shown, but this utility model is not limited thereto. In this embodiment, the pattern 120 is, for example, disposed on one side of the lens body 110, or for example, disposed on one half of the lens body 110, such as... Figure 1 and Figure 2 As shown, but the present invention does not impose specific limitations on this. In addition, the pattern 120 in this embodiment is, for example, disposed on the side of the peripheral area 112 away from the optical area 111, that is, close to the outer circumference of the peripheral area 112, but the present invention is not limited thereto.

[0026] In one embodiment of this utility model, the first thickness T1a of the first positioning part 114a can be smaller than the thickness T of the body part 113, such as... Figure 3 and Figure 4 As shown, this also allows for precise positioning of the pattern 120, ensuring an aesthetically pleasing fit when worn. Please refer to [reference needed]. Figure 3 and Figure 4 The corneal contact lens 100a of this embodiment is similar to the corneal contact lens 100, with the main difference being 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 corneal contact lens 100a is worn on the eyeball, the first positioning portion 114a, due to its smaller weight, will tend to move upwards, for example, so that the first positioning portion 114a can be located above the optical zone 111. In other words, in this embodiment, when the corneal contact lens 100a is worn, the first positioning portion 114a can be positioned on the eyeball, that is, it can be positioned above the pupil. Therefore, when the user wears the corneal contact lens 100a, the first positioning portion 114a can also position the pattern 120, ensuring an aesthetically pleasing fit.

[0027] This utility model uses a lens body 110 with a first thickness T1 of the first positioning part 114 that is greater than the thickness T of the body part 113, and a lens body 110a with a first thickness T1a of the first positioning part 114a that is less than the thickness T of the body part 113, so that when the user wears the corneal contact lenses 100 and 100a, it is easy to position the pattern 120 and ensure that the wearing is aesthetically pleasing.

[0028] Figure 5 This is a top view of another embodiment of the corneal contact lens of this utility model. Figure 6 For along Figure 5 A cross-sectional diagram of the CC section line is shown in the image. Please refer to the diagram. Figure 5 and Figure 6 In this embodiment, the peripheral region 112b of the corneal contact lens 100b further includes a second positioning portion 115. The second positioning portion 115 is opposite to and does not overlap with the first positioning portion 114b, and is adjacent to the body portion 113. The second thickness T2 of the second positioning portion 115 is, for example, less than the thickness T of the body portion 113, and the first thickness T1 is, for example, greater than the thickness T. Specifically, in this embodiment, the first positioning portion 114b and the second positioning portion 115 are, for example, located on opposite sides of the peripheral region 112b, but this invention does not impose specific limitations on this. In this embodiment, the second positioning portion 115 is, for example, similar to a crescent shape. Figure 5 As shown, but the present invention is not limited thereto. In another embodiment, the second positioning part 115 may be other shapes, such as elliptical (not shown).

[0029] In this embodiment, the first thickness T1 of the first positioning part 114b is, for example, greater than the thickness T, and the second thickness T2 of the second positioning part 115 is, for example, less than the thickness T. This is such that when the contact lens 100b is worn on the eyeball, the first positioning part 114b, due to its greater weight, will tend downwards due to gravity, while the second positioning part 115, due to its smaller weight, will tend upwards, for example. This allows the first positioning part 114b and the second positioning part 115 to be located below and above the optical zone 111, respectively. Thus, in this embodiment, when the user wears the contact lens 100b, the first positioning part 114b and the second positioning part 115 can position the pattern 120, ensuring an aesthetically pleasing fit.

[0030] It is worth mentioning that the pattern 120 of the corneal contact lens 100b is easy to position, and the positioning effect of the pattern 120 is more easily observed when the user wears the corneal contact lens 100b in both eyes simultaneously. For example, as Figure 8As shown, when a user wears contact lenses 100b in both eyes simultaneously, the patterns 120 of both contact lenses 100b are positioned at the same location on the corresponding eyeballs, resulting in a very aesthetically pleasing fit. On the other hand, although not shown in the figure, since contact lenses 100 and 100a also have pattern positioning effects, when a user wears contact lenses 100 in each eye or contact lenses 100a in each eye separately, it also has a similar effect. Figure 8 The positioning effect shown.

[0031] Furthermore, in this utility model Figure 5 and Figure 6 In the illustrated embodiment, the corneal contact lens 100b has a significant weight difference between the first positioning portion 114b and the second positioning portion 115, making the effect of gravity more pronounced. Therefore, the corneal contact lens 100b with the first positioning portion 114b and the second positioning portion 115 is easier to position, thereby making the pattern 120 easier to position.

[0032] In one embodiment of this utility model, the pattern 120 overlaps with, for example, the first positioning part 114. Figure 1 As shown, however, this utility model does not impose specific limitations on this. In another embodiment, the pattern 120 overlaps with, for example, the second positioning portion 115, as shown. Figure 7 As shown, the pattern 120 overlaps with, for example, the first positioning portion 114b, and the pattern 120 can extend from the first positioning portion 114b to the second positioning portion 115. It should be noted that this invention does not limit the pattern 120 to overlap with the first positioning portion 114b when it overlaps with the second positioning portion 115, nor does it limit the pattern 120 to extend from the first positioning portion 114b to the second positioning portion 115. In one embodiment, the pattern 120 may only overlap with the second positioning portion 115 (not shown in the figure), or the pattern 120 may not overlap with either the first positioning portion 114b or the second positioning portion 115. This invention does not specifically limit the relative positions of the pattern 120 with the first positioning portion 114b and the second positioning portion 115, and these positions can be adjusted according to design requirements.

[0033] In summary, this invention, by employing a lens body with a first positioning part, makes it easy for users to position the pattern when wearing contact lenses, ensuring an aesthetically pleasing fit. Furthermore, when the lens body of this invention also has a second positioning part, it makes pattern positioning even easier.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the methods and techniques disclosed above without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
