It is commonly reported that the pupils of women are larger than those of men and the pupils of myopes larger than those of emmetropes. However, these reports are not supported by experimental procedures using objective measurements, controlled conditions, and adequate numbers of subjects. In this report the open-loop pupil size was measured objectively using dynamic infrared pupillometry in a sample of 48 subjects. Subjects were balanced for age and equally divided between emmetropes and myopes, males and females. The results did not support the contention that females have larger pupils than males or that physiologic myopes have larger pupils than emmetropes.
