As we are all living in the digital era presently, the need of utilizing electronic devices such as computer keeps climbing in an astonishing speed. Heated discussions arose regarding to this matter. Personally, I firmly agree that the drawbacks of using a computer on a daily basis outweigh its advantages. In the following paragraphs my reasons will be explained from two aspects.
On the one hand, if children constantly use a computer, the first adverse effect it has on them is the harm of the computers' radiation might do to children's eye sights. It was scientifically proved that as kids are in their growing period of life, their eye sights tend to be easy to change, and children with a high frequency of watching computer screens usually have weaker eye sights. Secondly, people in younger ages often have strong curiosity but little self-discipline. Even some might say computers are able to help with children's study, but it is unavoidable that they will soon learn about the other uses of computer one way or another. They may be drawn to the games, or worse, contents involving violence, sex or drug use. Therefore, I believe it is physically and mentally unhealthy for kids to use computers everyday.
On the other hand, if it is the adults who use computers regularly, there also exists negative results. Firstly, their offsprings may learn from their behaviours, thus have higher risks of growing computer addiction. More importantly, the more time they spend on computers, the less they will be able to accompany their family members and friends, which will weaken their family bonds and friendship with others in the long run.
All in all, I totally agree that the negative influence of using a computer everyday outweigh its merits.
