Color matches were measured as a function of field diameter (1, 2, 4 and 8 deg) for 53 normal observers aged 13-80 yr. The difference between match midpoints for the 1 deg diameter and the other diameters decreased throughout adulthood, indicating an age-related change in optical density of cone outer segments in the central 1 deg. For all ages, there were large interobserver differences in the magnitude of the difference scores. These results provide an explanation for contradictions in the literature on the effects of age on cone optical density and on the magnitude of the color-match-area effect.
对53名年龄在13至80岁的正常观察者，测量了颜色匹配作为视场直径（1、2、4和8度）的函数。1度直径与其他直径的匹配中点之间的差异在整个成年期都在减小，这表明中央1度区域中视锥细胞外段的光密度存在与年龄相关的变化。对于所有年龄段，观察者间在差异分数的大小上存在很大差异。这些结果为文献中关于年龄对视锥细胞光密度的影响以及颜色匹配区域效应大小的矛盾提供了解释。
