title: [Prevalence of myopia in Khakasia].
abstract: The paper presents the results of studying the prevalence of myopic refraction in adolescents in the Republic of Khakasia in relation to the state of their accommodation-convergence apparatus, constitution, ethnicity, and the type of a settlement. Myopia has been found to occur 3 times more frequently among the urban adolescents. The results have led to the conclusion that urban living conditions may be a determinant of enhanced refraction.
