Rayleigh matches for foveal, temporally alternating fields showed only a small increase in the log green/red matching ratio (0.03--average of 10 observers) as the field was decreased from 116 to 19 min arc. This is consistent with only a small, 10%, change in photopigment density or lengthening of the cone outer segments in the central fovea. The change in matches with field size is considerably less than reported in several previous studies.
对于中央凹颞侧交替视野的瑞利匹配实验表明，当视野从116分视角减小到19分视角时，对数绿/红匹配比仅略有增加（0.03——10名观察者的平均值）。这与中央凹处视色素密度仅有10%的微小变化或视锥细胞外段长度的增加是一致的。视野大小变化所导致的匹配变化远小于此前多项研究中的报道。
