Fifty subjects were tested in regard to their sensitivity to scotomatic glare before and after wearing contact lenses. A statistically significant increase in glare sensitivity was noted in those subjects who developed epithelial edema while wearing their contact lenses, while no difference was found in subjects who did not develop epithelial edema. Lenses slipping below the pupillary border do not increase glare sensitivity.
