Description

[Technical Field]

[0001] The present invention relates to a functional contact lens, and more specifically, to a functional contact lens that can resolve various eye health problems by facilitating the smooth drainage and circulation of tears, allowing the tears to be uniformly distributed and floated in the tear film of the cornea, and enabling uniform drainage of tears. [Background technology]

[0002] The frontmost part of the human eye is the transparent corneal tissue, which acts as a convex lens to focus the light entering the eye.

[0003] Every time we blink, a small amount of tears is secreted from the human eye, coating the surface of the cornea and conjunctiva. This helps to ensure clear, uniform vision, washes away foreign matter, and fulfills various roles, such as providing antibacterial effects through antibacterial substances (lysozime, gamma globulin) and supplying oxygen from the air to the surface of the cornea.

[0004] This tear film consists of three layers from the cornea: mucoid layer, aqueous layer, and lipid layer.

[0005] On the other hand, a typical contact lens 10 is in the shape of a spaceship as shown in Figure 1 and is worn on the front of the eye, mainly on the cornea, to correct vision. Of course, some contact lenses are also useful for eye treatment and are used for cosmetic purposes.

[0006] Depending on the material, contact lenses can be classified into hard contact lenses, soft contact lenses, gas-permeable hard contact lenses, etc. Figure 1 shows a soft contact lens 10.

[0007] A typical soft contact lens 10 as shown in Figure 1 floats on the tear film of the cornea. However, such contact lenses 10 have little movement on the cornea and do not allow for smooth circulation of the tear film, which can lead to problems such as a reduced supply of oxygen to the cornea and an inability to smoothly excrete metabolic products of the eye, such as carbon dioxide and lactic acid. This can lead to side effects such as corneal hypoxia, corneal erosion, peripheral corneal vascular infiltration, and corneal edema. Summary of the Invention [Problem to be solved by the invention]

[0008] The object of the present invention is to provide a functional contact lens that can solve various eye health problems by enabling smooth drainage and circulation of tears, allowing the tears to be uniformly distributed and floated in the tear film of the cornea, and enabling uniform drainage of tears. [Means for solving the problem]

[0009] The above object is achieved by a functional contact lens comprising: a lens body processed into a disk shape; and a plurality of through holes drilled in the lens body; the plurality of through holes allowing smooth drainage and circulation of tears when the lens body is placed in the tear film of the cornea, while guiding the lens body to be uniformly distributed and float evenly in the tear film of the cornea.

[0010] The lens body may include an optical portion formed in a center region; and a side portion formed radially outward of the optical portion, and the plurality of through holes may be formed in the side portion region of the lens body.

[0011] The number of the through holes may be 2 to 36, the diameter of the through holes may be 0.05 to 0.50 mm, and the area of ​​the side portion where the through holes are arranged may be 3 to 12.0 mm.

[0012] The through holes may be arranged concentrically and at equal intervals in the lens body.

[0013] The through-holes can be formed by laser processing. [Effects of the Invention]

[0014] According to the present invention, the discharge and circulation of tears can be smoothly performed, and the tears can be uniformly distributed and floated in the tear film of the cornea, and the uniform discharge of tears can be achieved, thereby having the effect of resolving various eye health problems.

[0029] Referring to these figures, the functional contact lens 100 according to this embodiment allows for smooth drainage and circulation of tears, allowing them to be evenly distributed and floated in the tear film of the cornea, and enabling uniform drainage of tears, thereby resolving various eye health problems.

[0030] Referring to these figures, the functional contact lens 100 according to this embodiment can include a lens body 110 processed into a disk shape and a plurality of through holes 120 drilled in the lens body 110 .

[0031] The lens body 110 may include an optical portion 111 formed in a center region and a side portion 112 formed radially outward of the optical portion 111, and a plurality of through holes 120 may be formed in the side portion 112 region of the lens body 110.

[0032] In this case, the number of through holes 120 may be 2 to 36. In this embodiment, 36 through holes 120 are used. In addition, in this embodiment, the diameter of the through holes 120 may be 0.05 to 0.50 mm, and the area of ​​the side portion 112 where the through holes 120 are arranged may be 3 to 12.0 mm.

[0033] Furthermore, the through holes 120 can be arranged concentrically and at equal intervals in the lens body 110, and the through holes 120 can be drilled in the lens body 110 by laser machining.

[0034] The functional contact lens 100 according to this embodiment having such a structure is a hydrophilic lens made of HEMA material, and can be directly attached to the eyeball to be used for vision correction (myopia).

[0035] In addition, 36 through-holes 120 are formed on the surface excluding the optical portion 111, i.e., the side portion 112, penetrating vertically on a concentric circle based on the center of the lens body 110. This allows each through-hole 120 to be uniformly distributed in the tear film of the cornea, allowing the lens body 110 to float evenly in the tear film and enabling uniform discharge of tears. This opens a passage for smooth discharge and circulation of tears, providing convenience in use.

[0036] According to this embodiment, which operates based on the structure described above, tears can be discharged and circulated smoothly, and the tears are uniformly distributed and floated in the tear film of the cornea, and the tears are discharged uniformly, thereby resolving various eye health problems.

[0037] In other words, the functional contact lens 100 according to this embodiment is uniformly distributed and floats evenly in the tear film of the cornea, and enables uniform discharge of tears, which not only facilitates the supply of oxygen to the cornea but also facilitates the discharge of metabolic products of the eye such as carbon dioxide and lactic acid.

[0038] Therefore, even when wearing the functional contact lens 100 according to this embodiment, side effects such as corneal hypoxia, corneal erosion, peripheral corneal vascular infiltration, and corneal edema, which have occurred in the past, do not occur or can be minimized. [Example]

[0041] Meanwhile, with this structure, the number of through holes 220 formed is less than that of the first embodiment, that is, two rows are formed.

[0042] Even when a functional contact lens 200 having such a structure is applied, the discharge and circulation of tears can be smoothly performed, and the tears can be uniformly distributed and floated in the tear film of the cornea, and the uniform discharge of tears can be achieved, thereby eliminating various eye health problems.
