RESUMEN
The parameters of functioning of muscular, cardiac-respiratory, vegetative and other systems in the organism of healthy persons engaged in the work connected with visual strength have been studied. The optimal limits of system response are determined and thus its realization is shown to be provided with the activation of vegetative regulation apparatus. The structure of the relations between the distinguished parameters is maintained even when new level of functioning is established. Initial activation of vegetative mechanisms is a leading factor of the further rearrangements of visual and somatosensory analyzers with the given kind of activity.

The investigation of microelectronic devices showed that the working conditions of microscope operators in general satisfy the sanitary and hygienic requirements with the exception of lighting of places of work and the conditions of objects' illumination in the field of microscope view, this being the main reason of visual fatigue. The earliest and most distinct fatigue signs involve the changes in color discrimination acuity, adaptation time to darkness, response time to light stimulus. The measures intended for optimization of working conditions of microscope operators are proposed.

The research was carried out at data processing sections of computer centres. The data on working conditions, psychologic work pattern and functional state of visual analyzer of 48 operators constantly working with displays were obtained. It was established that operators usually complained of visual fatigue, changes in colour perception, occurrence of retina angiodystonia. Recommendations on the optimization of labour conditions of those working with display terminals were given.
