Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA)Severity of hereditary defects of color vision depends on the degree of mutation of the OPSIN genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue. If a person's eye has no cone cells, then they cannot see any color at all. The rod cells, which increase in the peripheral field, provide only black and shades of gray.
