A pair of computer glasses can help solve your problems. Besides, you can give up using computers or try to limit the hour that you spend on playing computer games or working in front of the computer screen. I think TV and computer screen do great harm to our eyes. But people are reluctant to admit that their vision was impaired by computers, TV or other kind of high-tech products. These equipments help a lot in our daily lives and ruin our health as well. But have you noticed that we have spent too much time on them every day? Some of us just use them to kill time. Why not do some outdoor activities? That can help improve our health.
