Iris pigmentation and photopic visual acuity: A preliminary study
Department or Administrative Unit
Anthropology and Museum Studies
Visual acuity under varying conditions of light stress was tested in four human populations. It was found that the density of iris pigmentation had no significant effect on visual acuity under conditions of bright light. While some acclimatization to local light levels was observed, significant population differences in visual acuity were obtained. A hypothesis is advanced as to the adaptive value of varying densities of pigmentation of the iris based on the known heat absorption properties of melanin granules.
