The acuities of three subjects with good visual acuity and stereoacuity were reduced by the addition of diffusing filters placed before one or both eyes; these subjects then underwent automated stereoacuity and visual acuity tests. Results were idiosyncratic and differed from subject to subject to such an extent that no general rule sufficed to describe the effect of different degrees of blur on visual acuity and stereoacuity. It had been thought that blur degraded stereoacuity more than visual acuity but most of the results from one subject indicated the opposite effect. The effects of monocular vs. binocular blur are discussed.
通过在一只眼睛或两只眼睛之前放置漫射滤光片，降低了三名视力和立体视敏度良好的受试者的敏锐度；然后这些受试者接受了自动立体视敏度和视力测试。结果因人而异，受试者之间的差异程度之大，以至于没有通用规则足以描述不同程度的模糊对视力和立体视敏度的影响。人们曾认为模糊对立体视敏度的损害大于对视力的损害，但一名受试者的大多数结果显示出相反的效果。文中讨论了单眼模糊与双眼模糊的影响。
