Abstract

The refractive state of 321 children (160 boys and 161 girls) of a rural primary school were examined under the cycloplegic condition with 5% homatropine. The results obtained as folIow; 1. Among 321 children, the refractive errors was revealed in 28.0% and emmetropia was revealed in 72.0%. 2. As to the distribution of refractive errors, hyperopic eyes were 39.5% and myopic eyes were 60.6%. 3. The refractive errors were observed more frequently in girls (15.4%) than those of boys (12.5%). 4. There was a tendency that hyperopic refractive error was gradually decreased from 8 years of age as the age increased. However, myopic refractive error was incerased gradually from 8 years of age. 5. At the age of 11 highest incidence of the refractive errors was observed (22.8%). 6. The degree of most of refractive errors(98.4%) were revealed less than 3 diopters. 7. As to the type of astigmatism, with the rule was 51.4% and against rule was 42.9%.
