VISUAL ACUITY DECREMENTS ASSOCIATED WITH WHOLE BODY PLUS OR MINUS Gz VIBRATION STRESS

Abstract

The fact that vibration has an adverse effect on visual acuity is well established but inadequately quantified. The operational acceleration environments of low altitude terrain avoidance flight, the increasing use of helicopters, and the potential vibration problems associated with space flight launch and reentry all require a better understanding of visual performance under this stress. This study demonstrates that near, intermediate, and distant vision are differentially degraded under vibration stress. A method is presented to describe visual effeciency in terms of a Performance Index that should be useful to aeromedical scientists and clinicians, as well as design engineers.
