myopia positive light device

Abstract

The invention relates to a myopia corrector, comprising a pressure rod, a piston, a piston rod, a container body, a soft body contact base, a soft body contact film, a sealing cover, a fixing band, an elastic band and a telescopic connecting rod. In the two container bodies, the piston rod connecting the piston extends out of the container body through the opening above the container body, the pressure rod is connected to the two piston rods, the two container bodies are connected by a telescopic connecting rod, and the soft contact base is located below the container body. There is a sealing cover in the center of the soft contact base, and the sealing cover is connected with the soft contact base. The sealing cover is composed of a ring-shaped soft body and a ring-shaped soft contact film. There is a fixing belt connecting port on the outside of the two container bodies, and the fixing belt passes through The fixing band is connected to the port, and the elastic band is connected to both ends of the pressure bar. The invention has a simple structure, no need of special disinfection, no damage, controllable strength and direction continuously and stably.

Description

technical field [0001] The invention belongs to an eye vision training aid, in particular to a myopia corrector for correcting myopia and astigmatism. Background technique [0002] The incidence of myopia and poor vision remains high. According to public statistics, the incidence of myopia and poor vision among primary school students can reach more than 50% in high-incidence countries and regions, more than 80% among middle school students, and even higher among college students. The society still lacks safe and effective means and methods for the treatment and prevention of myopia at present. The main reason is that the mechanism of myopia occurrence is not clear, so that the occurrence and development of myopia and poor vision are left to their own devices. There is a lack of eye or vision items in Chinese and Western physical exercises. At present, there are only eye exercises in my country, but the exercise effect is not good. At present, there are many types of myopia...

AI Technical Summary

Problems solved by technology

There are some defects in the current instrument: first, it is difficult to prevent and control the axial length of the eye without touching the eyeball; second, contacting the cornea of ​​the eyeball will cause bacterial infection; third, it is difficult to control the magnitude and direction of the force, so there is no obvious effect, and even adverse reactions may occur

However, this intermittent effect is difficult to achieve a sustained effect
