    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. The apparatus comprises a lighting unit (14) composed of light emitting diodes (B, G, O, R); a hollow tube (17) receiving the lighting unit (14) at one end region; an ocular lens (15) arranged at the frontal other end of the tube; a diapositive slide arranged across the tube which has a transparent pattern allowing passage of light towards places of the retina of the subject, where vision is provided purely by cones; a current generator circuit (40) including respective controlled current generators associated with the diodes (B, G, O, R), a pulse generator coupled to control inputs of the current generators for controlling pulsation of current flowing through the diodes; and a potientiometer adjustable by the subject under test for adjusting the repetition frequency of the pulse generator.
