Myopia light correction machine

Abstract

The invention relates to a myopia light correction machine. The myopia light correction machine comprises a pressure rod, pistons, piston rods, container bodies, a soft contact base, a soft contact film, a sealing cover, a fixing strap, an elastic band and a telescopic connecting rod, wherein the two pistons are respectively and symmetrically arranged in the two container bodies; piston rods connected with the pistons extend out the container bodies from openings in the container bodies; the pressure rod is connected to the two piston rods; the two container bodies are connected through the telescopic connecting rod; the soft contact base is arranged below the container bodies, the sealing cover is arranged at the center of the soft contact base and is connected with the soft contact base;the sealing cover consists of an annular soft body and an annular soft contact film, a fixing belt connector is arranged on each of outer sides of the two container bodies, and is connected with theconnector; and the elastic belt is connected to two ends of the pressure rod. The myopia light correction machine is simple in structure, free from special disinfection, free from damage, and continuous and stable in controllable force size and direction.

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
