[Functional status of the visual analyzer in operators working with displays].

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.

[The working conditions of microscope operators and the ways for their sanitary improvement in the manufacture of microelectronic devices].

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.
