[Dynamics of visual functions in the conditions of glow and sodium lighting. II. Time of conscious reaction and visual space-hand localization].

The authors present the results of investigations performed in 20 young persons with normal sight. A trial of evaluation of the strain of the central nervous system in conditions of various kind of lighting was carried out basing on its close connection with the visual hand localization as well as with the time of the conscious reaction. Analyzed was the behaviour of the quoted functions as the time passed during the morning hours and the results of the examinations obtained in conditions of glow and sodium illumination were compared. They suggest a favourable influence of the sodium light on the discussed functions.
