Chuprov A.D., Voronina A.E., Petrosyan E.A. PRIMARY SCHOOL AGE: PREVENTION OF VISUAL DETERIORATIONThe study for vision acuity state among primary school age children was carried on the base of the lyceum school No.5 in Orenburg. The study included 649 children and their parents. According to the results of the examination all school children were divided into 3 groups: group 1 – children wearing glasses or contact lenses; group 2 – children without glasses or lenses, but with uncorrected visual acuity (UCVA) less than 0.8; group 3 – children without glasses or lenses and UCVA more than 0.8.
It was found out that the number of children, not wearing glasses or contact lenses, and having UCVA above 0.8, decreases from form 2 to form 4, while the number of children with an UCVA under 0.8 increases twofold. In all age groups of 9–11 years, the cause of wearing glasses or lenses in the majority was myopia (9 years – 50 %, 11 years – 77.7 %). Children who did not wear glasses or lenses with UCVA above 0.8 already in form 2 (9 years) had myopic refraction in 16.5 %. In schoolchildren with UCVA less than 0.8 who had not wear glasses or lenses, the cause of vision loss was myopia in the absolute majority of children in all groups, besides that in all forms there were children having middle and high degree myopia, who had never worn glasses.
The main factor affecting the state of view of in schoolchildren of 9 and 10 years was excessive watching TV, and in 11 years old schoolchildren – games in the phone and the tablet. A low awareness of parents about the quantity of their children visual load was revealed. Symptoms of dry eye syndrome are more pronounced in children who have glasses and lenses, parents are also not fully aware of its presence. Schoolchildren and their parents received medical report on the state of their vision, which included measures to improve and preserve vision, as well as prevention of visual impairment. They also received the results of the questionnaire, which included a comparison of visual load in children and their parents’ view on this matter.Key words: primary school age, visual state, myopic refraction, uncorrected visual acuity, visual load, dry eye syndrome.
