Rayleigh matches obtained from red-green color deficients with conventional methods show large individual differences within diagnostic categories. Similar matches obtained from the same observers with a large-field substitution method show much less variability and suggest that the differences observed among simple anomals, extreme anomals, and dichromats with conventional methods are probably not solely due to the visual pigments contained in the cones. A theory that attributes these differences to the relative number of abnormal cones present in the observer's retina is described.
用传统方法从红绿色觉缺陷者获得的瑞利匹配在诊断类别内显示出很大的个体差异。用大视野替代法从相同观察者获得的类似匹配显示出的变异性要小得多，这表明用传统方法在简单异常者、极端异常者和二色视者之间观察到的差异可能不仅仅归因于视锥细胞中所含的视觉色素。本文描述了一种理论，该理论将这些差异归因于观察者视网膜中存在的异常视锥细胞的相对数量。
