deuteranopia

deuteranopia

n. red–green color blindness in which the deficiency is due to absence of the cone photopigment sensitive to green light, resulting in loss of green sensitivity and confusion between red and green (see dichromatism). The condition may be unilateral (i.e., color vision may be normal in one eye). See also protanopia.
