Abstract

Rod influence on hue discrimination was assessed by the Farnsworth-Munsell 100-hue test. Rod influence was taken as the difference in error scores obtained after complete dark adaptation and during the cone plateau at three mesopic (23, 9, 3 td) and one standard (158 td) light level. On the FM 100, rods produced a differential discrimination loss along a tritan axis as compared with a red-green axis without any bias toward a rod confusion axis. Rods appear to impair discrimination mediated by S-cone pathways, which at moderate levels of illumination can differentially elevate tritan errors on the FM 100.

摘要

通过 Farnsworth-Munsell 100 色调测试评估视杆细胞对色调辨别力的影响。视杆细胞的影响被视为在完全暗适应后以及在三种中亮度（23、9、3 特罗兰）和一种标准亮度（158 特罗兰）下视锥细胞平台期获得的误差分数差异。在 FM 100 测试中，与红绿色轴相比，视杆细胞在蓝黄色轴上产生了差异性辨别损失，且没有对视杆细胞混淆轴产生任何偏向。视杆细胞似乎会损害由 S 视锥细胞通路介导的辨别力，在中等光照水平下，这会使 FM 100 上的蓝黄色误差有差异性地升高。
