Abstract
The luminosity curve shows how the sensitivity of the eye varies for various wave lengths. Sensitivity is measured in terms of the reciprocal of the energy required to produce a given effect[long dash]threshold, for example. The present experiments were performed to investigate, by improved techniques, the still not universally accepted fact of cone luminosity losses in deuteranopes. Also obtained were threshold luminosity data on a small group of protanopes. Results show that, as compared with normal subjects, both types of color-blind individuals demonstrate sensitivity losses; 5 of the 6 deuteranopes show a deficit of luminosity in the green-to-blue part of the spectrum, and all the protanopes show a loss in the red.This publication has 3 references indexed in Scilit:
