Abstract

Aviation systems incorporating sophisticated electro-optical displays frequently are designed without provision for use by spectacle-wearing pilots. Contact lenses offer a solution to the compatibility problems experienced by Army aviators, approximately 18% of whom wear corrective lenses. Under a waiver from The Surgeon General, 44 helicopter pilots performed flying duties while wearing extended-wear soft and rigid lenses. Pilots remained in the study for a minimum of 6 months and a maximum of 24 months. Six experienced temporary discontinuance of wear (4-19 days); and six withdrew from the study. An overall wearing success rate of 86% was achieved. No pilot was grounded due to contact lens-related problems. Subjectively, extended wear contact lenses favorably affected job performance. This is the first major field evaluation of contact lens use by U.S. Army aviators while flying military aircraft.
