屈光参差与立体视觉

屈光参差是指两眼屈光度的程度和（或）性质有一定的差别，其主要相关原因是由于双眼眼轴长度发育不平衡。立体视觉是人类和高等动物所特有的一项高级视功能，同时也是人类从事多种工作及日常生活中必备的一种重要功能。屈光参差引起的视网膜像模糊和不等像视是影响立体视觉的主要原因。屈光参差矫正方法不同，对立体视觉的影响也是不同的。

Anisometropia and stereopsis

Anisometropia means a certain difference between two eyes in the degree of diopter and （ or ） the nature of diopter.The main associated reason is due to the eyes ocular axial length development imbalance. However, stereopsis is the highest visual function of human beings and higher animals, which is necessary for working people in daily life. The main reason of effecting on binocularity is retinal image blur and aniseikonia caused by uncorrected anisometropia. Different methods of anisometropia correction have different effects on stereo vision.
