[The results of research on visual fatigue in children by determining the perception time of a sequential color contrast].

The paper analyses results after a study of visual fatigue by means of determining the perception time of a color successive contrast in children, aged from 10 to 13 years, before and after intensive dosed visual load. The revealed high percentage of visual fatigue in children (40.4-52.5%) is likely to be connected with the fact that the study was made in spring time when signs and body asthenization, avitaminosis are expressed. It was found that perception of a color successive contrast in children with eye myopization is shorter as compared with children with stably normal visual acuity.
