A study of the frequency and intensity of using various types of electronic devises by 229 senior students showed that the average duration of using a computer and a laptop for the holiday period is about 4 hours. This is two times higher than on school days (p < 0.05), the duration of continuous operating time with them is about 3 hours, while on school days it did not exceed more than 2 hours (p < 0.05). We believe that it is necessary to extend the positive experience of health improving activities for the holiday period. The high proportion of child care institutions in the Russian Federation (81.3 %), with about 50 % of the total number of children enrolled in summer health improvement company, allows to be recommended these institutions as a platform for health improving activities. Our methods showed positive results in the children health improving with functional disorders and chronic diseases of the vision organ in the child care institution during the one summer health improvement company. They showed significant positive dynamics of visual acuity in 81 % of cases (p < 0.05), and improved results of the Malinovsky test.
