在速示器,以随机点立体图对为刺激,测量了正常和弱视者的立体视和形状视感知时间。实验表明:正常被试需要大约100ms感知深度,110ms或更长时间感知形状。这二种感知时间与刺激视差的种类和大小无关。弱视者需要比正常人较长的时间达到立体和形状的视感知。这二种感知时间的差别,弱视者也大于正常人。视锐度和立体视范围均恢复到正常的弱视者,以上二种感知时间,可以达到正常人范围,也可能显著地大于正常人。 In the rapid display device, a random point stereoscopic pair is used as a stimulus, and stereopsis and shape perception time of normal and amblyopic patients are measured. Experiments show that: the normal subjects need about 100ms perceived depth, 110ms or longer perceived shape. These two perceptions are independent of the type and size of stimulus parallax. The visually impaired need to achieve stereoscopic and shape perception over a longer period of time than normal. The difference between the two perceived time, amblyopia are also greater than normal. Visual acuity and stereopsis range returned to normal amblyopia, the above two kinds of perception of time, you can reach the normal range, but also may be significantly larger than normal.
