Materials and methods. The study involved 109 specialists of medical centers (25 ophthalmologists, 31 representatives of the secondary medical staff - nurses and paramedics, 53 office employees). The anonymous survey concerned the assessment of working conditions and their impact on the functional state of the body of the respondents. Performance and stress tolerance indicators were evaluated using three standard questionnaires. The study of 66 subjects' levels of glutathione in the blood: total, reduced, oxidized and the ratio of reduced and oxidized - was used to analyze the relationship of the neuro-emotional nature of labor with the reaction of oxidative stress. Statistical processing of the obtained data was carried out using traditional methods of variation statistics and calculating the value of the odds ratio (OR) with a 95% confidence interval (CI). Results. The survey revealed a significant proportion of people in all groups of respondents who constantly use computer technology in their work. Describing the quality of the processed information, doctors more than representatives of other groups note its complexity, importance, negative emotional color, a high degree of responsibility and tension. Doctors more often than average medical staff and office workers associate the manifestation of fatigue with an uncomfortable state of the visual organ, nervous system, and musculoskeletal system. The subjects showed reduced performance and stress tolerance with the most pronounced negative trends in the group of doctors. Changes in the glutathione system were detected, indicating the presence of oxidative stress in 40% of ophthalmologists and office workers, and in half of nurses. Conclusions.
