Human eye exposure to light of 2.5 .times. 103-50.0 .times. 103 nit leads to transient color blindness, decrease in the central color, bright contrast sensitivity and decline in functional stability of color discrimination. Pre-exposure to light luminosity of 50.0 .times. 103 nit enhances the decrease in functional stability of color discrimination due to vestibular stimulation. This is accompanied by a decline in vestibular tolerance. Mechanisms of the changes in color discrimination and resistance to vestibular stimulation are discussed.
