Samenvatting
Colour vision tests are used for a wide variety of purposes. Some of these include the rapid screening of congenital red-green defects in industry, transportation, and the military. The classification of discrimination ability within the population of congenital red-green defects is used for job assignment purposes. Another use for screening involves the recognition and diagnosis of congenital disorders for psychophysical or genetic study. In the clinic, screening is used for the recognition and differentiation of congenital and acquired disorders, for the classification of acquired disorders in patients with eye disease, and, in some cases, for the assessment of treatment or for tracking recovery from disease or trauma.
