Rayleigh matches for foveal, temporally alternating fields showed only a small increase in the log green/red matching ratio (0.03—average of 10 observers) as the field was decreased from 116 to 19 min arc. This is consistent with only a small, 10%, change in photopigment density or lengthening of th...
