Description

Technical Field

[0001] The present invention relates to a functional contact lens, and more particularly, to a functional contact lens that can smoothly discharge and circulate tears, and can be evenly distributed and suspended on the tear film of the cornea, while enabling uniform discharge of tears, thereby solving various eye health problems. Background Art

[0002] The front surface part of the outermost front side of the human eye is a transparent tissue called the cornea. The cornea acts as a convex lens and is a transparent tissue that converges light entering the eye.

[0003] Each time a person blinks, a small amount of tears is secreted and coats the surface of the cornea and the conjunctiva. Its functions include: providing clear and uniform vision, flushing foreign objects, exerting antibacterial effects through antibacterial substances (such as lysozyme, gamma globulin), supplying oxygen from the atmosphere to the corneal surface, etc.

[0004] This tear film is divided into three layers, namely, the mucoid layer, the aqueous layer, and the lipid layer, in sequence from the cornea outwards.

[0005] On the other hand, a conventional contact lens 10 has a flying saucer shape as shown in Figure 1 and is worn in front of the eyeball, mainly on the cornea, to correct vision. Of course, some contact lenses are also used for purposes such as assisting eye treatment or beauty.

[0006] Contact lenses can be classified into hard contact lenses, soft contact lenses, gas-permeable hard contact lenses, etc. according to material properties. Figure 1 This is a soft contact lens 10.

[0007] As shown in Figure 1 a conventional soft contact lens 10 is suspended on the tear film of the cornea. However, due to the poor mobility of this contact lens 10 on the cornea, the circulation of the tear film is not smooth, which may cause the following problems: reduced oxygen supply to the cornea, unsmooth discharge of intraocular metabolites (such as carbon dioxide, lactic acid, etc.). As a result, the following corneal side effects may occur: corneal hypoxia, corneal erosion, corneal limbal neovascularization, corneal edema, etc. Summary of the Invention

[0010] Means for Solving the Problem

[0011] The above object is achieved by a functional contact lens, which is characterized by comprising: a lens body processed into a disc shape; and a plurality of through holes formed by perforating the lens body. When the lens body is disposed on the tear film of the cornea, the plurality of through holes enable smooth discharge and circulation of tears, and at the same time guide the lens body to be evenly distributed and evenly suspended on the tear film of the cornea.

[0012] The lens body may include: an optical portion formed in a central region; and a side portion formed radially outside the optical portion, and the plurality of through holes are formed in a region of the side portion of the lens body.

[0013] 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 region of the side portion provided with the through holes may be 3 to 12.0 mm.

[0014] The through holes may be arranged concentrically and equidistantly on the lens body.

[0044] The lens body 110 may include: an optical portion 111 formed in the central region; and a side portion 112 formed radially outside 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.

[0045] At this time, the number of the through holes 120 may be 2 to 36. In the present embodiment, 36 through holes 120 are adopted. In addition, in the present embodiment, the following conditions may be satisfied: the diameter of the through holes 120 is 0.05 to 0.50 mm, and the region of the side portion 112 where the through holes 120 are arranged is 3 to 12.0 mm.

[0046] In addition, the through holes 120 may be arranged concentrically and equidistantly on the lens body 110, and the through holes 120 may be formed by laser processing to perforate the lens body 110.
