长期看近必然引起近反射,其中过度调节可以引起假性近视。过度集合时,眼外肌对眼球的压迫又有可能导致真性近视。为解决在近环境中防治近视,作者根据视觉生理学的理论,设计了用近目标模拟远目标作用的双眼合像法,并进行了防治近视的实验观察。双眼合像法即用一张纸卡丽上a<——>,b<>两个合像视标便成为合像卡片(两视标间距应为两眼看远时的视线距)。将此卡放在眼前,令受试者忽而合像即模拟看远(将a、b两视标融
Long-term look near inevitably cause near reflex, in which excessive regulation can cause pseudo-myopia. Excessive collection, extraocular muscle oppression of the eye may cause true myopia. In order to solve the problem of prevention and treatment of myopia in the near environment, the author designed a binocular imaging method that simulates the far target with a near target according to the theory of visual physiology, and conducted experiment observation on prevention and treatment of myopia. Binocular co-ordination that is to use a piece of paper on a card Carrie a <->, b <> two as a visual icon will become a co-card (the distance between the two targets should be two when looking away from sight distance). The card on the front, so that the subject suddenly, as far as the analog look far (the a, b two standard melt
