  • Abstract
  • Look Inside

Subjects with congenital color vision defects were questioned by mail whether and how they have en-countered faulty color recognition during their daily life. Out of a total of 785 undergraduates and alumni of University of Tokyo with color vision defects, 375 gave frank responses.

The incidence of faulty color recognition was cor-related with the degree of color vision defect, or mild anomalous trichromat, anomalous trichromat and di-chromat in the ascending order. No significant differ-ences were noted in the incidence between protanopes and deuteranopes.

The reported faulty color recognisition seemed to be due to three characteristic features in color vision deficiences : loss of sensitivity in long wavelengths in protanopes, color confusion along isochoromatic linesand low colorimetric purity near the neutral point.
