Abstract : The possible inhibition of cone function by rods in the dark adapted eye was investigated with the use of spectrally selective light adaptation. Yellow and blue adapting lights of equal photopic luminance were equivalent in their adapting effect on the photopic process. Recovery of the scotopic process was significantly delayed following adaptation to blue light, however. A dark adaptation function based on an acuity criterion which required the function of cones showed no influence of scotopic recovery, whether such recovery occurred relatively early after yellow adaptation or relatively late after blue adaptation.
