DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color contact lens used by persons with cataract or photosensitivity.

[0002]

2. Description of the Related Art A cataract, in which the eyes become white and become invisible due to irregular reflection such as ground glass when sunlight shines on the eyes, can be cured by surgery, but is relatively young or the cataract progresses. Surgery may be inappropriate depending on the degree. For example, there is a case where a side effect or the like due to surgery is concerned. I tried to wear sunglasses for such patients. The pupil of a conventionally marketed color contact lens is transparent because the purpose is fashion.

[0003]

In the case of a cataract, even if sunglasses are worn, light enters through the gap between the eyes and the sunglasses, and the front of the eyes becomes white due to the irregular reflection phenomenon such as ground glass, making it invisible. is there. Also, when interacting with a person wearing sunglasses, it may be troublesome to give the other person a strange feeling. Therefore, eyeglasses that eliminate the above-mentioned disadvantages have been desired for cataract patients and people with photosensitivity.

[0004]

A color contact lens for cataract according to the present invention is arranged such that when sunlight or the like hits the pupil in the center of a transparent contact lens body, the diffused reflection phenomenon like ground glass causes the pupil in front of the eye. The contact lens body has an iris colored in the form of an iris pattern, and the pupil in the center of the iris is used for the sunglass effect. A certain color lens. In addition, the color contact lens has a visual acuity correcting effect.

BEST MODE FOR CARRYING OUT THE INVENTION

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a cataract color contact lens according to the present invention. The pupil portion 2 having a diameter of about 5 mm at the center of a transparent contact lens body 1 having a diameter of about 14 mm and a center thickness of about 0.07 mm made of a soft or hard synthetic resin is exposed to sunlight or the like. When hit
A color lens having a so-called sunglass effect, which has the same effect as known sunglasses that can prevent the front of the eyes from becoming white due to the irregular reflection phenomenon like a ground glass, and having the same color as the pupil. As the synthetic resin, a polymer with a water content of about 38%, which is mainly composed of hydroxyethyl methacrylate, is used. The density and color of the color lens are for sunny weather, cloudy weather, and various types are prepared according to individual differences. I do.

An iris portion 3 colored in an iris pattern such as blue, green, light brown, gray, brown, black, light green, etc. is provided on the contact lens body 1, and the diameter of the central portion of the iris portion 3 is about 5 mm. In the pupil part 2 of
A color lens of the same color as a pupil having a sunglass effect that prevents the front of the eyes from becoming white due to the irregular reflection phenomenon such as ground glass when sunlight hits the eyes.

Thus, the cataract color contact lens is provided with so-called mere sunglasses having no lens effect for correcting visual acuity, and a lens having a lens effect capable of correcting visual acuity.

[0009]

According to the cataract color contact lens of the present invention, like when wearing conventional sunglasses,
The disadvantage that light enters through the gap between the eyes and sunglasses and the front of the eyes becomes white and becomes invisible due to the irregular reflection phenomenon such as ground glass is eliminated.

[0010] Also, since it is difficult for others to understand wearing color contact lenses, it is no longer possible to give the other party a strange feeling as in the case of wearing conventional sunglasses.

[0011] The color of the pupil and iris can be selected as desired, and the fashionability is high.
It is used not only by cataracts and photosensitizers but also by general use to provide eye protection.
