Nowadays, thanks to the development of technology, computer is now indispensable to life. Some people think that computer is good for children and it should be used daily by children but some others think differently. In my opinion, the latter opinion is true.
  First, using computer constantly has bad influence on children's eyes. When they concentrate on computer for too long, their eyes will get tired, which is the main reason for some eyes problems.
   Moreover, children who play games too much on computer can seriously lack communicating skills, they will know little about the outside life. It is a well-known fact that people who are addicted to games, especially online games, can eventually bear dangerous consequences.
Finally, even people who are not interested in online game can still be negatively affected by using computer too much.
