摘要

This paper presents the results of studying the psychophysiological and morphofunctional state of the visual analyzer of eight male subjects after being exposed to 11-day-long dynamic light-emitting diode illumination under hermetic chamber conditions. A comprehensive eye examination did not reveal any significant effect of the short-term (not more than 11 days) exposure to artificial LED light; however, the psychophysiological characteristics of the visual analyzer function were impaired. Loss of relative accommodation and the narrowing of peripheral visual fields for green and blue may be due to asthenopia (visual fatigue) developing in closed space. Electrophysiological investigations have revealed a P100 bifurcation, which indicates changes in the morphology of the pattern-reversal visual evoked potentials (VEPs). This phenomenon may be representative of a temporal discord of visual channels or a change in their temporal characteristics caused by specific artificial illumination conditions.
