Nowadays, people spend a lot of time watching TV and staring at computer screen, which do great harm
to their eyes. And more and more people are becoming near-sighted.
Why are there so many people becoming near-sighted? The first reason, in my mind, is that an increa-
sing number of people turn to televisions and computers, and the harmful rays from the screens are
inclined to impose nearsightedness on people. Furthermore, the high demands from from society lay g-
reat pressure on people, thus everyone is encouraged to read more and more to keep up with world. L-
ast but not least, many modern people do not have a good habit of using eyes--they overuse their ey-
es and wear unsuitable glasses.
The harmulness of eyesight deteriorating has become more than obvious at the moment. First of all,
wearing glasses damages people's images. In the second place, nearsightedness can cause a lot of in-
conveniences to people's daily life. Thirdly, it can even cause some other serious diseases.
Consequently, it is high time that we made great efforts to put an end to eyesight deteriorating.
