I wanted to share an experience about computer .Many of us wear glasses (and many are about to).I think people whose job is related to computer (like programmers) must try to keep their eyes as well as the first they they sat in front of computer .I have several tips for keeping eyes healthy that you may want to read :
Position your screen about an arm’s length from your eyes and 20 degrees below eye level.
Set colour and contrast tones to suit your eyes, and match the brightness of your screen with your surroundings.
Minimize reflected glare on your screen by using dimmer switches on lights and a protective anti-glare screen cover. Also consider positioning your screen so that it sits perpendicular to windows and other bright light sources. If you are having trouble locating the source of the glare, turn off your monitor to reveal a darkened screen, and tilt/swivel your monitor until the reflection disappears.
Keep your screen free of fingerprints and dust, as both can reduce visual clarity.
If you alternate between looking at your screen and paperwork, consider obtaining a clipboard that attaches alongside your monitor so that the two are at the same working distance.
Use the 20-20-20 rule. Every 20 minutes take a 20 second break and focus your eyes on something at least 20 feet away (the water cooler, possibly?). This will give your eyes a much-needed break and reduce some of the symptoms mentioned earlier.
Remember to blink! Did you know that on average we blink 12 times per minute, but when we’re on the computer, we only blink 5 times per minute? That can add up to dry eyes. Relieve the discomfort by using artificial teardrops or gels and remembering to blink. Consult your optometrist to determine which eye drops are best to relieve your dry eyes.
Ask for anti-reflective coatings on the lenses of your glasses, which can be applied at the time of manufacturing, to protect your eyes from bright and/or flickering light sources such as fluorescent lights. Your Doctor of Optometry can even talk to you about eyewear designed specifically for computer use.

Bullshit.
You will understand the value of health later ....
I think if you are a programmer it will ge important for you to read this article
This guy aradhya is clearly a rude troll. Ignore him.
By the way, sometimes during a contests when time matters much, people will probably be reluctant to use 20-20-20 rule :D.

This is epic! Especially some answers: stick a cactus in front of your screen and it will absorb all radiated visible light :D
The most effective prevention, that's for sure :D
When I say
Hello Worldalso say "goodbye" to my eyes...and I'm now very happy with my choice :)
Funny enough, back in 1998 when I was deciding on future career, one of inputs was from my parents — they said "We don't want you to be programmer. You already have glasses and we don't want you to stare at computer display all your life". Maybe in 1998 this sounded somewhat reasonable, but now it is just funny. Now I am Accountant / Financial Analyst with CFA designation, which is very good for my field. I am not a programmer, but guess what — I still spend all my life staring at computer display :).
And probably there is still a failed IT specialist somewhere "deep inside", otherwise I wouldn't join websites like Codeforces or Topcoder.
