Abstract

Three centuries of experimentation in optics, psychophysics and biochemistry established the dependence of color vision on three kinds of light-absorbing molecules, or pigments, in the cone cells of the retina. The author has isolated the genes that encode the pigments and has identified genetic anomalies that lead to color blindness.

摘要

三个世纪以来在光学、心理物理学和生物化学领域的实验证实了色觉取决于视网膜锥体细胞中三种光吸收分子（即色素）。作者已经分离出了编码这些色素的基因，并识别出了导致色盲的基因异常。
