A selective filter, such as the X-chrom lens, which is placed before one eye, serves to create a luminance difference between the two eyes. The amount of the luminance difference is dependent upon the wavelength distribution of the stimulus and could therefore serve as a clue to assist color discrimination. The ability to detect and discriminate levels of luster is investigated. One of three subjects shows a crude ability to discriminate levels of luster. The performance level is such that a filter may aid dichromacy but not anomalous trichromacy.
一个选择性滤光片，比如X染色体镜片，放置在一只眼睛前面，用于在两只眼睛之间制造亮度差异。亮度差异的大小取决于刺激的波长分布，因此可以作为辅助颜色辨别的线索。对检测和辨别光泽度水平的能力进行了研究。三名受试者中有一名表现出了粗略的辨别光泽度水平的能力。其表现水平表明，一个滤光片可能有助于二色视，但对异常三色视无效。
