ˈcolour-ˈblindness a. The condition of being colour-blind; a visual defect, consisting in inability (greater or less) to discriminate between different colours, or shades of colour. This optical defect was first described by Dalton in 1794 (Mem. Lit. & Phil. Soc. Manchester V. 28), and was for a considerable time known scientifically as Daltonism. The accuracy of the words colour-blind and colour-blindness has often been impugned; in scientific use achromatopsy occurs; J. Dixon Diseases of the Eye (1859) 279 suggested the term acritochromacy (ἀκριτο-χρωµατία), with its adjective acritochromatic.
