Everyday, I always play computer games. I'm fun of watching Tv too. I know that this activities that I have, I'm always prone to radiation. Are these activities can destroy my eyes and at the same time my vision too?

    

Well,yes.Activities such as playing computer games and watching too much TV can harm our eyes.
Some simple exercise can help relieve the stress on eyes.
1.Place your palm on your eyes.Gently press your eyes for 5-7 seconds and then release.
Repeat this 5 times.
2.Keep a wet cotton near you and whenever your eyes burn. place it over your eyes.
3.While sleeping, place two thin slice of cucumber over your eyes, it cools your eyes.
Love your eyes..

If you are always playing video games, surfing the internet and watching tv, be sure to keep a good distance away from the monitor or tv. This will keep you away from radiation particles coming from these devices.

And I suggest you to use screen protectors to refrain radiation from coming out of these devices.

It is for sure that your eyes will suffer through eye vision problem.Do you wear spectacles?You can protect your eyes by wearing special types of glasses that protect against the rays coming from monitor and TV.I have got them for my eyes you also can make them from a good optician.If you find your eyes burning then wash with cool water and then close your eyes for few minutes and then you will feel nice.

As far as my knowledge goes, it's all about the distance from the screen.
Another thing that you can do, which most people wont tell you, is to reduce the brightness of whatever you are looking at.
Trust me, it's easier for your eyes to adjust.
