Macular degeneration in people over 60 years of age or strokes that damage the retina or affect particular areas of the brain could also lead to colour blindness. In Deutan-type CVD, the spectral sensitivity of the M-cone is shifted toward longer wavelengths so that it effectively receives too much red light and not enough green light.
