Abstract
Method for detecting color vision deficiencies of a subject by determining his or her spectral sensitivity curve, wherein the spectral sensitivity curve is determined by critical fusion frequency spectral scanning at predetermined discrete narrow bands of wavelengths, preferably being blue, green, orange and red. The compensation of the color vision deficiency occurs by using a compensation color determined on the basis of differences between a standard sensitivity curve and the measured one. In each wavelength where such differences are experienced, the intensity of the light source generating that wavelength is increased or decreased in accordance with the extent and sign of the difference, and the compensation color is obtained by illuminating all light sources.
