Visual Characteristics of Navy Divers
Abstract
The results of a series of visual tests given to 153 divers are presented. They show that the divers, who are a highly select population with regard to vision, remain so through their tours of duty. Their mean acuity is 20/20, their depth perception and color vision are excellent, an large percentage than would be expected exhibit normal phorias, and their mean point of accommodation exhibits a normal decline with age. In addition, the mean calibres of their retinal arteries and veins and the artery/vein ratios are completely normal. Compared with submarines, the divers have significantly better acuity at distance, better depth perception and less refractive error. Their visual performance, however, is worse in certain respects than that for unselected samples of the population from previous generations.
