Abstract

Convergency insufficiency is typical symptoms such as blurring of distant vision, reexamination of near vision, jumping words and walking while reading, visual fatigue and so on after reading or working closely for a period of time, According to the corresponding symptoms and signs, visual function tests were carried out, such as far and near eye position, accommodative response (BCC), positive relative accommodation (PRA), negative relative accommodation (NRA), near point of convergence (NPC), accommodation amplitude (AMP), etc., The detected visual function data were evaluated according to the normal value of Morgan and Sherad criteria. In daily life, people not only require clear vision, but also pay great attention to the comfort of using eyes, and the convergency insufficiency has become one of the important factors hindering the clarity, persistence and comfort of vision. Making binocular vision system to produce the cognition of regulation, convergence and eye movement through various methods such as optics, psychology and physics, vision therapy improves the application ability of eye vision system, and finally cures visual function problems such as visual fatigue, adjustment and convergence abnormality. We review the incidence, pathogenesis, new progress in the treatment of convergence insufficiency, the mechanism of visual formation and the basic principles of visual training.
