monochromat
Person who has a condition of monochromatism (total colour blindness). There are two types of monochromats: the cone monochromat whose photopic luminosity curve resembles the normal and who has normal visual acuity and dark adaptation; and the rod monochromat whose retina does not contain functional cones and, therefore, has poor vision, photophobia and sometimes associated nystagmus and myopia. Monochromats are very rare: estimated at about three persons in 100 000. See achromatopsia; defective colour vision; cone dystrophy.
