Successive Color Contrast in Defective Color Vision

open access: yesThe Tohoku Journal of Experimental Medicine, 1956
Retinal induction was studied in normal and color-defective subjects by means of Motokawa's method. 1. The effect of light in terms of ζ was investigated with spectral lights, and it was found that the ζ value for red lights was dicidedly small in a protanomalous. 2.
