The response of the pupil was measured to a foveally fixated small field in which checkerboards were alternated with a blank field of equal average luminance. The subjects studied had refractive errors, but their eyes were free from pathological changes. A pupil visual acuity could be derived, which showed a very high correlation with the subjective acuity with the same checkerboard stimuli. The method of obtaining pupil visual acuity seems to compare favorably with other objective methods of measuring visual acuity.
测量了受试者注视中央凹的小视场时瞳孔的反应，在该视场中棋盘格与平均亮度相同的空白视场交替出现。所研究的受试者有屈光不正，但他们的眼睛没有病理变化。可以得出瞳孔视力，其与相同棋盘格刺激下的主观视力显示出非常高的相关性。获得瞳孔视力的方法似乎比其他测量视力的客观方法更具优势。
