Abstract
In order to elucidate the relationship between low visual acuity and environmental factors including the video display terminal usage among school children, we measured the visual acuity of the 557 elementary school children and analysed the data from questionnaire about life pattern pertaining to video display terminal usage. The results were as follows;
1. There was a tendency of gradual increase of low visual acuity with grade(p<0.01).
2. The low visual acuity in female was higher than that in male. (p<0.01).
3. It is statistically significant that low visual acuity was related with glasses wearing of parents(p<0.05).
4. It is statistically significant that the time of watching TV, computer operation and duration of computer education were related with low visual acuity respectively(p<0.05).
From the above results, we have got a conclusion that low visual acuity was related not only with hereditary factors, but also with environmental factors including the video display terminal usage. So it is conceived that the instructions for proper usage of video display terminal are required for prevention of low visual acuity among school children. And further studies on causal relation between low visual acuity and video display terminal usage are required.
