FEATURES OF STUDENTS' VISUAL PERFORMANCE IN THE DYNAMICS OF THE EDUCATIONAL PROCESS
The article presents the results of assessing the visual performance of first-year students during one school day. Visual acuity and psychophysiological parameters were studied. Classes were held in a mixed format - both in the traditional form and by demonstrating multimedia presentations in the process of presenting lecture material. The results of assessing visual acuity in 55 students without signs of visual pathology made it possible to determine the indicators of visual acuity for both eyes in the dynamics of the working day. It was found that after the completion of classes, a significant decrease in visual acuity was recorded in 38% of the examined. The subjective assessment of the state of the visual system of students in the dynamics of the educational process decreased by 18,27%, which may be the result of visual fatigue. Visual-intellectual load led to a decrease in the performance of neurons in the cerebral cortex and visual performance.
