Failure to meet required visual standards provides a significant source of rejections to naval aviation training and of disqualifications of designated aviators for Service Group I. It is important to assure these standards represent the visual abilities which are critical to mission performance, and to assure their proper application throughout the aviators career. The purpose of this report is to assess the visual characteristics of stratified samples active dutyretired within the naval aviation community through the examination of health records, to determine the distribution of those characteristics, and to identify those characteristics that have been noted to change during the course of the naval aviators career. The findings, based on an examination of 72 health records, show that with increasing age there are decreases in visual acuity and accommodative amplitude, increases in against-the-rule astigmatism and myopia, and stability in fusion-related variables and intraocular pressure.
