We live in 21 century, which is a century of modern technologies. An average person can’t imagine his life without mobile phones, computers, TV and another electronic gadgets nowadays.

But have you ever become thoughtful about desrtructive power of modern items? Undoubtedly, they influence on our health greatly, and especially on your eyes.

If you use a computer more than two hours a day, you could be suffering from Computer Vision Syndrome (CVS). It is a temporary condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time. Some symptoms of CVS include headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, polyopia, and difficulty refocusing the eyes.

According to The American Optometric Association almost 71 percent of those who have reported experiencing the symptoms of Computer Vision Syndrome wear eyeglasses or contact lenses. These people also report more eye, neck and back pain than people who do not use optical aids.

What can we do to reduce deleterious effect of computers?

Some scientists give following advices:

1. Blink Often: When looking at a computer or hand-held digital device, it’s common for you to blink two to three times less than you normally would. This can lead to “dry eye”. Blinking bathes your eyes in tears, and tears are naturally therapeutic for the eyes.

2. The 20/20/20 Rule: When spending long periods in front of a digital device, every 20 minutes, spend 20 seconds looking at something 20 feet away to allow your eyes to rest.

3. Ensure Proper Lighting: Poor lighting often causes eye strain. To help ease the strain on your eyes, keep bright lighting overhead to a minimum and position your desk lamp to shine on your desk, and not at you. Position your computer screen in a way that reduces reflections and glare from windows or overhead lights.

4. Location of computer screen: Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be about 4 or 5 inches(13 centimeters) below eye level as measured from the center of the screen and 20 to 28 inches(50-70 cm) from the eyes.
