The human visual system undergoes continuous anatomical, physiological and functional changes throughout the life span. There is also continuous change in the spectral distribution and intensity of light reaching the retina from infancy through senescence, primarily due to changes in the absorption of short-wave light by the lens. Despite these changes in the retinal stimulus and the signals leaving the retina for perceptual analysis, color appearance is relatively stable during aging as measured by broadband reflective or self-luminous samples, the wavelengths of unique blue and yellow, and the achromatic locus. Measures of ocular media density for younger and older observers show, indeed, that color appearance is independent of ocular media density. This may be explained by a renormalization process that was demonstrated by measuring the chromaticity of the achromatic point before and after cataract surgery. There was a shift following cataract surgery (removal of a brunescent lens) that was initially toward yellow in color space, but over the course of months, drifted back in the direction of the achromatic point before surgery. The spatial characteristics of color mechanisms were quantified for younger and older observers in terms of chromatic perceptive fields and the chromatic contrast sensitivity functions. Younger and older observers differed with small spots or with chromatic spatial gratings near threshold, but there were no significant differences with larger spots or suprathreshold spatial gratings.

老化眼睛的色彩空间视觉。

人类视觉系统在整个生命周期中经历持续的解剖学、生理学和功能变化。从婴儿期到衰老期，到达视网膜的光的光谱分布和强度也不断变化，这主要是由于晶状体吸收短波光的变化。尽管视网膜刺激和离开视网膜进行感知分析的信号发生了这些变化，但通过宽带反射或自发光样本、独特的蓝色和黄色的波长以及消色差轨迹测量，颜色外观在老化过程中相对稳定。事实上，对年轻和年长观察者眼介质密度的测量表明，颜色外观与眼介质密度无关。这可以通过重整化过程来解释，该过程通过测量白内障手术前后消色差点的色度来证明。白内障手术（摘除棕褐色晶状体）后出现了颜色空间的转变，最初颜色空间偏向黄色，但在几个月的时间里，又回到了手术前消色差点的方向。根据色彩感知场和色彩对比敏感度函数，对年轻和年长观察者的色彩机制的空间特征进行了量化。年轻和年长的观察者在小光斑或阈值附近的彩色空间光栅方面存在差异，但在较大光斑或阈值上空间光栅方面没有显着差异。
