Abstract

The percent area change under dark and light conditions was measured for subjects who wore photochromatic lenses and for subjects who wore clear glass lenses. There was no significant difference found between these two groups. There appears not to be any adaptive response of the pupil to lessen its ability to constrict, even though photochromatic lenses have taken on the role of the pupil to control the amount of light entering the eye.
