Last week, our teacher asked us to do a research in groups on the myopia problem of our class. The figures showed that of the 50 members, there were 30 near-sighted classmates. We looked into the reasons as well. There were 18 people watched TV or computer screen for too long, and another 9 read books with a incorrect posture, and the other 3 for unknown reasons. Since there are more near-sighted classmates in our class, I suggest that our fellow students should learn the right posture for reading and reduce the hours watching TV.
