In conclusion, teenagers are addicted to playing on computers and video games mainly because they wanted to escape from reality, or of peer pressure. Although we can learn about a lot of things on the internet, using the internet too much harms us, for example, we will have lesser time to communicate with family members and friends, causes us to have dry eyes too and we may neglect our studies. Therefore, we have to control our time on using the computer or playing video games to avoid computer addiction. If you found that you are addicted to using the computer or playing video games, self-discipline yourself, set your own timetable of using the internet, or if necessary, talk to a friend or a teacher to seek help.
