어린이 시력과 생활 환경과의 관계에 관한 연구

다국어 초록 (Multilingual Abstract)

This study was carried out to investigate the effect of environmental factors on 380 children`s unaided visual acuity and to determine the visual acuity and objective refraction error of these children. The unaided visual acuity and objective refraction error were measured by the TOPCON chart projector and refractometer on 147 kindergarteners and 233 primary school children ranging from age 5 to 12. The measurement on the unaided visual acuity of children were 3~o for below the 0.1 visual acuity 9% for 0.1∼0.4, 18% for 0.5∼0.7, 16% for 0.8∼0.9, and 54% for over 1.0 visual acuity respectively. The refractive errors were 9.350 for mixed astigmatism, 14.5% for hyperopia 75.88% for myopia, and 0.27% for emmetropia, respectively. When analyzing the environmental factors, the relationship between the children`s visual acuity and the number of hours the children watched TV, the more hours they watched TV, the more the children lost their visual acuity. The visual acuity of children decreased abruptly in the groups that watched TV more than 4 hour a day. When comparing the relationship between the children s visual acuity and proximity to the TV, the further away from the TV they were the higher visual acuity. There is mo relation between the children`s visual acuity and the studying hour or reading hour of children. The relationship between the children`s visual acuity and their dwelling environment, the visual acuity of children who lived in an independent house were better than the visual acuity of children who dwelled in an apartment.
