tokens: Computer has negative effects to children 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, typically shortsighted . 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 . For instance, several teenagers play games without rest, which leads to health depression, a typical example is the death of Korean gamer, who had a non-stop playing for 3 days . Finally, even people who are not interested in online game can still be negatively affected by using computer too much . Some social surveys have shown that a few children use computer for studying purpose, most of them are attracted by facebook, blog, etc . instead . Due to this neglect, they will have a bad result in school because when they can not live without internet, they will have no time for their studying . In conclusion, although it is undeniable that computer is a crucial part of human life, it still has its bad side, especially for children . People should learn how to use it properly to make it an effective tool because computer should be used not only for entertaining but also for working and studying purpose .
