The computer methods for determining the map of colour-contrast sensitivity of the retina, suitable for mass screening of the earlier disturbances of visual and circulatory systems of humans, are discussed. The expressions for calculation, and the results of the determination of the threshold values of the photon fluxes at which young people detect the light stimulus in the shape of the red square with the side 2 mm, formed on the screen of CRT display, are given.
