Description

Myopia prevention and control glasses

Technical Field

The utility model relates to an eyesight correction glasses technical field, more specifically the myopia prevention and control glasses that says so.

Background

The children just born are hypermetropia, the hypermetropia degree of the eyes is gradually reduced along with the growth and development of the children, and then the children play mobile phones, books, writing and the like in short distance due to poor eye use, and the eyes are highly regulated for a long time due to too many eyes used in short distance, so that ciliary muscle spasm is increased, the expansion capacity of the two eyes is reduced, the own hypermetropia is completely used up, the crystalline lens begins to thicken (the axis of the eyes is increased), the vitreous body is deformed, and axial myopia is formed.

Some anti-myopia lenses are also available in the market at present, and the lenses have some effects when used for a short time, but the eyes cannot be fused and cannot be excessively adjusted and gathered due to the incapability of adjusting the eyes after being used for a long time, so that the effect of relaxing the eyes is not achieved, and the aim of adjusting fatigue is only temporarily solved.

Therefore, the research on the myopia prevention and control glasses which do not affect the accommodation ability of eyes after long-term use and have good myopia prevention effect is a problem to be solved by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a short-sighted prevention and control glasses that can not influence eyes' accommodation ability for long-time use.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

myopia prevention and control glasses includes: the lens body is divided into an upper light area and a lower light area;

the lens of the upper light area is a concave lens;

the lens in lower light zone is convex lens and prism's composite mirror, the prism with convex lens integrated into one piece.

The technical proposal has the advantages that the middle and upper light areas of the utility model are used for the myopia patients to see far; the lower light area is used for the myopia patients to see near; in one day, the eyes are used more closely, and the combination of the convex lens and the triangular prism in the lower light area can relax ciliary muscles of the eyes for a long time, increase the hyperopia reserve of the eyes and open a binocular set; the long-term use of the combination of the convex lens and the triangular prism can cause the reduction of the adjusting capacity of eyes, so that the concave lens in the upper light area is used for seeing far, the adjusting capacity of the eyes can be recovered, and the purposes of adding far vision reserve for the eyes and not influencing the adjusting capacity of the eyes are achieved.

Preferably, the diameter of the lens body is 60-80 mm.

Preferably, the horizontal distance between the upper optical center of the upper light area and the lower optical center of the lower light area is 1.5-2.5 mm.

Preferably, the vertical distance between the upper optical center of the upper light area and the lower optical center of the lower light area is 14-16 mm.

Preferably, the upper light area is-6.00 to-0.00D concave lens, and the concave lens can be applied to a wide power range and is convenient for myopes with different powers to wear.

Preferably, the lower light area is a combination of + 3.50- +0.50D convex lens and a triple prism, the convex lens can be applied to a wide range of degrees, and the glasses can be conveniently worn by myopes with different degrees for different adjustments.

According to the above technical scheme, compare with prior art, the utility model provides a myopia prevention and control glasses, its beneficial effect does the utility model provides a lens this body is divided into the glazing district that is used for seeing the usefulness in a distance for see the lower light zone of near usefulness, the glazing district be concave lens, down the light zone be convex lens and prism's combination mirror, reached both for eyes increase hyperopia deposit, do not influence the effect of the accommodation ability of eyes again, play the effect of preventing and controlling myopia.
