Presbyopia correction glasses

Abstract

To solve the problem that after the age of 40, the strength of a ciliary body gradually decreases, making it more difficult for a crystal lens to adjust focus, and making it harder to read, and in order to prevent the problem and improve the strength of the ciliary body and adjustment of focus of the crystal lens, it is necessary to improve the strength of the ciliary body.SOLUTION: Small lenses of different focal lengths are arranged around a circumference of a glass lens, and a plastic ring with letters written on it is attached in front of them. The lenses are arranged on the circumference in two ways: one with a thicker crystal lens that allows the letters to be seen; and one with a thinner crystal lens that allows the letters to be seen. As the letters are read in order, the crystal lens repeatedly thickens and thins to strengthen ciliary muscles. At the same time, reading letters at the edge of the field of vision also trains the eye to maintain a wide field of vision. Additionally, by rotating eyeglass lenses with different focal lengths one frame at a time along the frame, the arrangement of thick / thin lenses can be changed to eliminate any bias in the small lenses due to position.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to eyeglasses that improve the ciliary muscles that adjust the thickness of the crystalline lens, which weakens with age, and improve presbyopia while also providing training to improve visual fields. Summary of the Invention [Problem to be solved by the invention]

[0002] As we age, we begin to lose focus when we see things. This is simply because the ciliary muscles weaken and are unable to adjust the lens of the eye. To improve this, we need to strengthen the ciliary muscles. [Means for solving the problem]

[0003] A number of small lenses 5 with different focal lengths are arranged around the circumference of the glasses, and a plastic ring 4 with letters corresponding to each small lens 5 is attached in front of them. The small lenses 5 are arranged around the circumference, with some allowing the letters to be seen if the lens is thicker and others allowing the letters to be seen if the lens is thinner. By reading the letters 3 in order, the lens repeatedly thickens and thins, strengthening the ciliary muscles. At the same time, reading letters at the edge of the field of vision also trains the wearer to maintain a wide field of vision. Furthermore, the arrangement of the thick and thin lenses can be changed by rotating the small lenses 5 with different focal lengths along the frame 1 one frame at a time. [Effects of the Invention]

[0004] By using the glasses of the present invention and training several times a day, it is possible to prevent and improve the weakening of the ciliary muscles, and it is also possible to read small letters. [Brief explanation of the drawings]

[0006] [Example]

[0007] Example 1 is a pair of glasses in which a plurality of small lenses 5 with different focal lengths are arranged on the periphery of the eyeglass lens 2, and a plastic ring 4 with corresponding letters 3 written on it is attached to the front. In order to read each letter 3, it is necessary to use the ciliary muscle to adjust the thickness of the lens, which leads to training of the ciliary muscle. In addition, because each letter 3 is arranged on the periphery of the eyeglass lens 2, reading the letter 3 not only adjusts the thickness of the lens, but also widens the field of view, thereby improving the ciliary muscle in a comprehensive manner.
