A retrospective survey of 5000 active aircrew records was performed at 12 United States Air Force USAF bases to obtain information about the prevalence of spectacle wear and refractive error. The data revealed that 27.4 of pilots and 51.5 of navigatorsweapons systems operators NavWSO required spectacles when flying. Of the spectacle-wearing pilots, 12.4 required bifocals. Myopia was the predominant refractive error and a relatively large percentage of aircrew members had astigmatism of 0.75 D or more, e.g., 33.1 of pilots. At the time of entry into the USAF, refractive error data were clustered around emmetropia with a definite skew toward hyperopia.
