NEAR VISUAL ACUITY UNDER LOW-LEVEL RED AND WHITE LIGHT
Abstract
The near visual acuity of 17 subjects between the ages of 35 and 45 years was measured under white light and red light of a 0.1 ft.-L. luminance level. The near visual acuity was significantly better under white light for the acuity demands of 20/30, 20/40, and 20/50. The visual acuity was equally good under red or white light when the acuity demand was 20/70 or larger, and the visual acuity was equally poor under red or white light when the acuity demand was 20/20.
