| Popis: | Objective. To determine the significance of changes in contrast sensitivity in the diagnosis of refractive errors in students of different ages. Object and methods of research. The scheme was used to study the visual analyzer of human age periodization, taking into account anatomical, physiological, social factors, which was adopted at the VII Conference on Age Morphology, Physiology and Biochemistry (1965). Since the load on the visual system begins to increase from about 4 years, our study included individuals (girls and boys) who belong to the following age groups: first childhood, second childhood, adolescence and adolescence. The study was conducted with the participation of 744 students, of which 393 were females and 351 males. In this work, each of the subjects was determined visual acuity using Golovin-Sivtsev tables, contrast sensitivity (CS) – using a table of contrasting optotypes. These indicators were determined for each eye separately. The values of CS |
