Problems solved by technology

[0005] In order to solve the problem of not being able to effectively prevent myopia from deepening myopia when using a pair of myopia glasses on the same occasion to look far and to read and write and watch computer screens, the myopia distance is twice the same. A kind of glasses for myopia and myopia work, which can solve the problem of not being able to effectively prevent myopia during long-term work by using a pair of glasses on the same occasion to see far and read and write and watch computer screens. The problem of deepening myopia

Embodiment Construction

[0018] The structure and usage of the myopia and myopia work glasses of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] The convex objective lens (3), the optical wedge (2) and the concave lens eyepiece (1) form the nearsighted optical system of the myopia eye glasses of the present invention. The diopter of the left-eye convex lens (3) is +1.5D to 3.0D, and the value in the example is +2.5D; the diopter of the right-eye convex lens (3) is +1.0D to 2.0D, and the value in the example is +1.5 D, the diopters of the two concave eyepieces (3) are selected according to the needs of the user, and the average value is -3.0D in the example.

[0020] The refraction angle of the optical wedge (2) is 2.7 Δ , which can alleviate the converging effect of the eyes to a certain extent.

[0021] Convex objective lens (3), optical wedge (2) and concave lens eyepiece (1) are contained in the mirror frame (4) as in...

Abstract

The invention relates to an optical element, especially a myopic glasses. In order to overcome the problem that the present myopic glasses are not suitable for the myopia to use for myopic operation, the invention provides the myopic operation glasses for the myopia, which is characterized in that two eyeglasses of the same pair of myopic glasses respectively have concave objective lenses, and the diopter of the concave objective lens in one eyeglass is about 1.5 times of that of the other eyeglass. The invention has the beneficial effects that the problem of the myopia degree deepening can not be effectively prevented by using the same pair of myopic glasses at the same occasion where people needs to see far and operates in a long time under a myopic distance and a middle sight distance which differ about one time of the myopic distance, the structure of the glasses is not complicated and the manufacture is not difficult.

Description

technical field [0001] The invention relates to an optical device, especially a kind of myopia glasses. Background technique [0002] The "myopia" spectacle lens usually worn by myopia is a periopic concave lens. The light reflected by the object will diverge after passing through the mirror to increase the viewing angle. This increased viewing angle is aimed at the distance vision of the nearsighted. When used for myopia, since the object is closer to the lens, the light reflected by the object will diverge to a greater extent after passing through the glasses. The closer the object is to the glasses, the greater the divergence of the reflected light will be after passing through the glasses. The opening angle of the nodes of the human eye is too large, sometimes even unacceptable, so it is occasionally seen that people with short-sightedness need to take off their glasses to see close objects clearly. Therefore, this " myopia " glasses are actually used for the myopia to ...
