Abstract:
645 children (330 boys and 315 girls) of a primary school were determined under 2% Cyclogyl. (1) Among 645 children, refractive error was 57.2% and emmetropia 42.8%. (2) As to the distribution of refractive errors, 33.8% were hyperopic and 11.4% myopic. Hyperopia was more common than myopia. (3) Hyperopic refractive error was increased until 7 years of age. Since then it has been decreased yearly. Myopic refractive error has been increased yearly since 8 years of age. (4) The refractive errors were relatively equall rate in girls(28%) and boys(29%). (5) Refractive errors were numerous around the age of 7(24.7%). (6) The degree of refractive errors varied, but in the great majority was less than 3 diopters. (7) As to the type of astigmatism, 75% were with the rule and 23.7 were againat the rule. (8) The myopic refractive errors were decreased in 1973 year(24.7%) than 1957 year(27.5%).
