In the study of the labor activity of computer users, the development of fatigue was noted during the work shift [2, 31, changes in their voltage were shown with different duration of periods of work behind the screen, as well as in the presence of breaks in work [4]. The data of a number of authors indicate that computer users sometimes have vision impairment and ametropia develops [5, 6]. There are no works characterizing the features of ensuring activity in persons with different refractions. We studied the nature of work, software engineers and the peculiarities of their adaptation to work at the display with commensurate and myopic refraction. The research was carried out in the computing center. Before the start of the study, 79 software engineers were examined ophthalmologically, and most of them showed myopic refraction.
We observed 10 apparently healthy male software engineers (with 2-5 years of experience in the specialty), whom we divided into 2 groups: the 1st group consisted of persons with emmetropic refraction, with a visual acuity of 1.0, with transparent refractive media in the normal state of the fundus; Group 2 - persons with myopic refraction from 3.0 to 5.0 D (moderate). All software engineers have a progressive non-hereditary form of myopia. To assess the refraction, skiascopic studies were carried out with drug cycloplegia (Sol. Homatropini, 1%).
Based on subjective data, 89% of programmers find working behind the screen more tedious. Impaired visual acuity with a predominance of myopic refraction was noted in 54.5% of the examined patients.
The data of the mathematical and statistical analysis of the heart rhythm made it possible to reveal a high level of functioning of the circulatory system, a closer connection of the autonomous regulation circuit with the central one in persons with emmetropic eye refraction than with myopic, which indicates a higher degree of tension of regulatory mechanisms during adaptation to this type of activity.
