condition of double vision. Hemi- means half and an- means without; thus, hemianopia means
lack of vision in half the visual field. Nyctal/o means night; therefore, nyctalopia means night
blindness. Exo- means outward and -tropia means turned condition; hence, exotropia is outward
turning of the eye.
