Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic contact lenses, in particular to single-layer bioenzyme-degradable cosmetic contact lenses. Background Art

[0002] Nowadays, as myopia is becoming more and more common, cosmetic contact lenses have become a popular household product. However, most of the cosmetic contact lenses on the market have problems such as difficulty in removing them, contact lenses slipping, contact lenses broken into pieces and unable to be removed from the eyes, and low breathability. In addition, wearing cosmetic contact lenses for a long time can damage the cornea, and some ingredients in cosmetic contact lenses are also harmful to the cornea. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a single-layer bio-enzyme-degradable cosmetic contact lens, which solves the problem that the existing cosmetic contact lenses are inconvenient to remove and have poor air permeability.

[0004] To achieve the above objectives, the utility model is implemented through the following technical scheme: a single-layer bio-enzyme-degradable cosmetic contact lens, including a non-degree transparent lens, the structure of the non-degree transparent lens is a single-layer hydrogel film, the material of the single-layer hydrogel film is P-HEMA hydrogel, and a dyeing area is provided on one side of the single-layer hydrogel film, and an organic pigment area is provided in the dyeing area.

[0005] Preferably, the diameter of the single-layer hydrogel membrane is 14.2 mm.

[0006] Preferably, the diameter of the organic pigment area is 13.5 mm.

[0007] Beneficial Effects

[0008] The utility model provides a single-layer bioenzyme-degradable cosmetic contact lens, which has the following beneficial effects:

[0009] 1. The designed cosmetic contact lenses can degrade by themselves, which can reduce the risk of infectious diseases caused by eye damage when removing cosmetic contact lenses, and solve the problem of people's difficulty in removing cosmetic contact lenses. The non-powered transparent lenses of the cosmetic contact lenses are made of a single-layer hydrogel film made of P-HEMA hydrogel. The P-HEMA hydrogel is soluble in biological enzymes, which achieves the special effect of self-degradation of the cosmetic contact lenses in the human eye, preventing wear on the cornea. Even if the lenses are broken in the eyeball, they will not cause damage to the eyeball. The single-layer hydrogel film is lighter, thinner and more breathable, which makes the wearer have a more comfortable experience and reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] See also Figure 1 The utility model provides a technical solution: a single-layer bioenzyme-degradable cosmetic contact lens, comprising a non-degree transparent lens 1, the structure of the non-degree transparent lens 1 is a single-layer hydrogel film, the material of the single-layer hydrogel film is P-HEMA hydrogel, and a dyeing area 2 is provided on one side of the single-layer hydrogel film, and an organic pigment area 3 is provided in the dyeing area 2; the principle of biodegradable cosmetic contact lenses is to utilize the metabolism of microorganisms to decompose the cosmetic contact lens materials into low molecular weight compounds, which are then absorbed and utilized by organisms in nature. This process does not require additional chemical treatment and meets the requirements of environmental protection and sustainable development. The main material of biodegradable contact lenses, P-HEMA hydrogel, consists of natural polymer materials and synthetic polymer materials. Natural polymer materials such as chitosan and cellulose have good biocompatibility and degradability. Synthetic polymer materials such as polylactic acid (PLA) and polycaprolactone (PCL) can also be biodegraded through specific chemical structure design. Compared with traditional non-degradable contact lenses, biodegradable contact lenses have the following advantages: First, biodegradable contact lenses can decompose naturally after being discarded, reducing the pressure on landfills and the environment. Second, the raw materials of biodegradable contact lenses are widely available and highly renewable, which helps to achieve the recycling of resources. Finally, the production process of biodegradable contact lenses is usually more environmentally friendly and reduces the emission of harmful substances.

[0014] Furthermore, the diameter of the single-layer hydrogel film is 14.2 mm, and the diameter of the lens is 14.2 mm, which is more suitable for the eye size of Asians.

[0015] Furthermore, the diameter of the organic pigment area 3 is 13.5 mm, and the coloring diameter is 13.5 mm, and the characteristics are diversified color selection, UV blocking, and meeting the needs of different activities.

[0016] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.
