Abstract

A vision unscrambler for treating amblyopia, myopia, hyperopia and strabismus is composed of case body, main visual target board in the case body, and controller for controlling the flash variation of visual targets. A number of visual targets are arranged in the maximal visnal filed on said main visual target boards. The flash variation of visual targets forces eyes to move in the maximal visualfield, so exercising and coordinating the functions of eyes and promoting benigh development of eyes. Its advantage is short unscrambling period.

Description

Technical field: [0001] The invention relates to a vision correction instrument. Background technique: [0002] At present, the arrangement of the visual targets of the eye care therapeutic instrument is within a small field of view. For example, if the visual targets are arranged in a lens barrel, the visual targets are arranged in a triangle, straight line, or small arc, and usually consist of three or four visual target light-emitting diodes. A group of visual targets, each group of visual targets flashes alternately or simultaneously, and then forms a kaleidoscopic image through the refraction and reflection of the three mirrors. Using this kind of therapeutic apparatus, due to the small field of vision, the eyes can only move in a small range, the amount of eye activity is small, the correction time is long, and the recovery of vision is only effective in a short period of time, and it is easy to rebound after a long time; this therapeutic apparatus cannot make the eyes...
