eye refractor

Abstract

The invention relates to an eye refraction shaping instrument, which comprises an airtight container body, a soft body contact base, a soft body contact film, a sealing cover, a pressure device, a B-ultrasound device, a telescopic connecting rod and a fixing belt, and two airtight container bodies pass through Connected by a retractable connecting rod, there is a probe of the B-ultrasound device in the airtight container body, a soft body contact base is located under the airtight container body, and a sealing cover is arranged in the center of the soft body contact base, and the sealing cover is connected with the soft body contact base through threads, and the sealing cover is connected by a ring Shaped soft body and ring-shaped central soft film, the side of the airtight container is provided with a small hole for connecting the pressure device. The outer sides of the two airtight container bodies respectively have a fixing belt connecting port, and the fixing belts are connected through the fixing belt connecting port. 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 auxiliary instrument, in particular to an eye refraction shaping instrument 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 pres...

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
