Television and Myopia

ABSTRACT

To investigate the relationship between the watching television and myopia, 301 middle school students of different school grade and sex were given questionnaires of the average television watching period per a day and examined the degree of myopia by the manifest refraction. The results showed that no statistically significant correlation existed between the degree of myopia and the television watching period, however the degree of myopia progresses with advancing school grade. From this results, we concluded that the usual television watching is not related to the degree of myopic refractive changes.
