Strabismus and amblyopia therapeutic instrument

Abstract

A strabismus and amblyopia therapeutic instrument relates to the field of strabismus and amblyopia treatment equipment. The therapeutic instrument comprises a control module, and a light source assembly, a function module and an eyepiece which sequentially arranged along a light path, wherein a shading sheet and a driving device used for driving the shading sheet to move are arranged between the eyepiece and the light source assembly; the control module is electrically connected with the driving device, the function module and the light source assembly; the light source assembly comprises at least one semiconductor green laser and at least one semiconductor red laser. According to the strabismus and amblyopia therapeutic instrument, the semiconductor green laser and the semiconductor red laser are used for generating green light and red light with specific wavelengths, and thus cone cells are efficiently stimulated. Meanwhile, the protection effect of the shading sheet is utilized, itis guaranteed that laser power acts on human eyes after being stable, harm of the laser to the human eyes is avoided as much as possible, and safety is improved.

Description

technical field [0001] The invention relates to the field of strabismus and amblyopia treatment equipment, in particular to a strabismus and amblyopia treatment instrument. Background technique [0002] Amblyopia is a common eye disease in children, with an average incidence rate of 3.5% nationwide. Amblyopia is caused by non-organic lesions, and those whose corrected visual acuity cannot reach 0.9 due to functional factors are called amblyopia. There are many treatment methods for amblyopia, including covering method, depression therapy, grating therapy, afterimage method and red light filter therapy, fine work training and homoopia training, etc. [0003] At present, there are many types of amblyopia treatment instruments on the market, but most of them use divergent light sources with a large wavelength range, and the proportion of light waves that can effectively stimulate the cone cells is small, which cannot make the cone cells produce effective excitatory stimulation...
