Description
CONTACT LENS HAVING CORNEAL REPAIR FUNCTION
BACKGROUND OF THE UTILITY MODEL
Technical Field
The present utility model relates to a contact lens, and more particularly to a contact lens having a corneal repair function.
Related Art People have been plagued by vision impairment and degradation for a long time.
Visual impairments suffered by many people and related to abnormal light refraction such as myopia, hyperopia, and astigmatism are mainly caused by such factors as long-time improper usc of eyes, extreme fatigue, and stress, which incurs abnormal contraction and poor blood circulation to the two most important muscles, the ciliary muscle and the radial muscle, for controlling the light refraction, which therelore results in stiffness, deformation, and loss of function, thereby making the visual focus fail to fall on the retina correctly.
For the impairment to the vision, a myopic person usually wears a pair of frame glasses or contact lenses of certain degrees, so as to enable the eyes to have a clear vision. When compared with the frame glasses, the contact lenses have a few of advantages. For example, the contact lenses do not have any impediment from the frame, the wearer does not feel any additional weight burden, and the appearance of the wearer is not affected.
Further, unlike the frame glasses, soft contact lenses do not have the risk of possible lens cracking, so that the contact lenses bring more convenience to persons doing sports.
Contact lenses mainly include rigid lenses and soft lenses. The rigid contact lenses are harder than the soft lenses with respect to the material. Conventional materials used in hard lenses mainly include non-gas permeable polyrnethyl methacrylate (PMMA) and rigid gas permeable (RGP) contact lenses.
Advantages of the rigid ones are as follows. The material does not contain any water, and the lens does not adsorb substances such as protein and sediments easily. When the lenses are worn, if dust enters into the eye, the wearer call feel discomfort immediately, and although the discomfort is felt, the cornea is prevented from being harmed by tile dust that enters the eyes of the wearer.
However, the rgid contact lenses have many limitations in use. For example, in intense exercise, it is better not to wear the rigid contact lenses, so as to prevent the vision of the wearer from being impaired by the rigid lens that breaks in the eye.
The other kind of conventional contact lenses is soft lenses made o1 for example, silicone hydrogels, polyacrylamide (PAA), polyhydroxyethylmethacrylate or poly(2-hydroxyethyl methacrylate) (pHEMA), which brings desirable comfort to a wearer when in use, and is the mainstream of the current market due to the low price.
However, the soft lens adsorbs residues such as protein or fat easily, thereby resulting in the pi-oblern of protein fixation and attachment during wearing. Further, if dust enters into the eye of the wearer, since the lens contains water, which makes the wearing comfortable, the wearer may not feel the invasive dust or suspended particulates, but in fact the dust that enters the eye has damaged the surface of the eye cornea of the wearer.
Therefore, long-time wearing will definitely more or less harm the surface of the eye tissue, which, if not treated timely, may incur other complications to the eyes, such as impairment to the cornea.
In view of the above, no matter what material the contact lenses arc made of, and not matter how long the contact lenses are worn, the surface of the eye tissue is definitely more or less harmed, and the problem is inevitable even if the material of the contact lenses is ever changing.
Therefore, to solve the problems of the cunent contact lenses with respect to the structure and material to enable the contact lenses to have a cortical repair function, which is aimed to improve the quality of life and eye health of wearers of the contact lenses, is an objective to be achieved persons in the art.

The diameter of the central transparent region 31 is about 3-7mm. That is to say, a difference between the inner diameter and the outer diameter of the peripheral region 30 is about 6-17 mm. The difference between the inner diameter and the outer diameter refers to the outer diameter of time peripheral region (the donut-shaped material) minus the inner diameter. Besides, the thickness of the scale material layer from the edge of the central transparent region 31 to the edge of the peripheral region 30 may vary according to needs, which depends on the degree of myopia and the degree of astigmatism of the wearer.
