light-adapted eye

Etymology: AS, leoht + L, adaptatio + AS, eage

an eye that has been exposed to bright light long enough for chemical and physiological changes to take place, such as bleaching of the rhodopsin or visual purple. The loss of cone sensitivity to light may require increased light intensity to obtain the same degree of visual acuity. Also called photopic eye.
