The invention relates to medicine, more precisely to hygieology and ophthalmology, and can be used for preventing deterioration of the sense of sight and also for improving the sense of sight of users reading off a screen. The invention increases the level of comfort and the reliability of the inventive method. The inventive method consists in influencing the user's eyes by additional pictures on screen, whereby an image is formed whose shape and color have a relaxing effect on a visual analyzer. The duration of exposure of the additional pictures is organized in such a way that makes it possible to restore the content of adenosine triphosphate and oxygen in the eye tissue; time intervals between exposures is less than time needed for acidulation of tissues and for the occurrence of a lack of oxygen. In the beginning the user watches such additional pictures whose shape and color range have a relaxing reflect on the visual analyzer region in the central nervous system (CNS). The shape and the color range of the additional pictures which have a relaxing effect on the visual analyzer are selected in such a way that they perform a relaxing effect on lateral and transversal eye muscles. The time interval between the images ranges from 20 to 150 min, the duration of exposure is selected within a range of 1.0 to 6.0 min. Together with the relaxing effect on a visual organ, said relaxing action is also exerted on an organ of hearing and muscles of the neck. The shape of at least a part of the additional pictures is smooth and roundish without distinct lines and boundaries.
