If you don’t do anything about them, it could affect more than your eyes. You could also have issues with your work performance.

There's no proof that computer use causes any long-term damage to the eyes. But regular use can lead to eye strain and discomfort.

How Is It Treated?

A few simple changes to your workspace can improve your symptoms and prevent new problems:

Cut the glare. Change the lighting around you to reduce the effect on your computer screen. If light from a nearby window casts a glare, move your monitor and close the shades. Ask your employer to install a dimmer switch for the overhead fixtures if they're too bright, or buy a desk lamp with a moveable shade that casts light evenly over your desk. You can also add a glare filter to your monitor.

Rearrange your desk. The best position for your monitor is slightly below eye level, about 20 to 28 inches away from your face. You shouldn't have to stretch your neck or strain your eyes to see what's on the screen. Put a stand next to your monitor and place any printed materials you're working from on it. That way, you won't have to look up at the screen and back down at the desk while you type.

Give your eyes a break. Follow the 20-20-20 rule. Look away from the screen every 20 minutes or so and look at something around 20 feet away for about 20 seconds. Blink often to keep your eyes moist. If they feel dry, try some eye drops.

Tweak your settings. You don't have to live with the factory-installed presets if you're uncomfortable. Adjust the brightness, contrast, and font size until you find what’s best for you.

Visit your eye doctor regularly for exams and to keep your prescriptions up to date. Let him know about any problems you have. You may need glasses or contact lenses. He’ll decide if you can wear your regular glasses for computer work or if you need a special pair. He might prescribe a single or bifocal lens, or tinted lens material to boost contrast and filter out glare.

Get your kids' eyes checked, too. Make sure any computers they use are set up at the right height and in the best light. Encourage them to take frequent breaks from the screen to give their eyes a rest.
