Abstract
It is experimentally found that LEDs illumination does not cause a negative influence on visual organs and human body as a whole. It is shown that changes of visual organ functional indices for visual operations are within the correspondent boundaries of physiological fluctuations and have a reversible nature. Integral indices of LEDs illumination efficiency from visual working capacity and visual fatigue degree are estimated. A practical importance of the obtained results is shown.
