The female incidence of congenital dyschromats corresponds to the square of the males in the Northern European populations, but this relation is not always true in the non-white races. The above-mentioned facts in the non-white races which are theoretically strange are considered to be caused by an anti-glare factor of pigment epithelium in their eyes, on the assumption that the abnormal color sense of color defectives may be a special form of visual dysfunction glare pointed out by IINUMA.
