Abstract
-
Visual acuity was measured on subjects while they were exposed to short periods of weightlessness aboard an aircraft flown through "zero-g" trajectories involving transition from 1 g to 2-1/2 g to zero g. Monocular and binocular acuity of near and far vision were measured on both Snellen and checkerboard targets. Control measurements were made on the ground and inflight at 1 g in counter-balanced sequence with the zero-g measurements. Results show that the weightless environment produced for this study has a detrimental effect on visual acuity as measured. The decrement is not considered to have practical significance.
