Computer and Your Eye Health

Computers have become an integral part of everyone's life. They have made things so much fast and simple but have brought with them new problems related to the eyes. These problems affect all those who spend a significant time working on the computers everyday. However, these computers related eye problems are mostly due to our own wrong habits. We call this cluster of problems e-Pain (which may mean electronic / eye pain) or Computer Vision Syndrome.

Causes
An understanding of what causes computer vision syndrome can help us take appropriate preventive steps. It is important to know that computer monitors do not emit any harmful rays or radiation (monochrome or color). The causes of the trouble are:

1. Constantly gazing at the monitor.
2. Decreased rate of blinking.

Computer users do not have to worry about significant electromagnetic radiation being emitted from their screens unless their computer screen is faulty or more than 20 years old. Nor should users fear cataracts. There is not enough evidence to substantiate the presumption that computers cause cataracts.

Trouble seeing the computer can trigger pains in other areas, such as the neck. People with bifocal glasses are especially prone to neck aches because they may have to tilt their heads back to see things up close. Working glasses are available to alleviate that problem. These are like reading glasses but the prescription is for the preferred distance from the computer screen to the eyes. Another way to avoid neck strain is to make sure your eyes are level with or slightly above the computer screen. You can also prevent postural problems and other aches by centering your keyboard under your computer screen.


There are simple steps one can take to limit the amount of eye fatigue or strain you may experience when working at a computer for long periods of time, including:

Taking twenty-second “eye breaks” and focusing on objects far away during the breaks. Try to incorporate these breaks every thirty minutes of work time.
* Use of document holders to keep your eyes from constantly having to refocus on different media with different lighting.
* Reduce the glare on the screen. (eliminate or reducing overhead or direct light, invest in a LCD Glare filter)
* Use Glare Guard to reduce glare.
* Rob rotation, such as switching tasks every 30-60 minutes in order to reduce strain on eyes and increase overall productivity by being active.
Place your screen 20 to 26 inches away from your eyes and the top of the screen at or a little below eye level. The monitor distance should allow you to read the screen without leaning your head, neck, or trunk forward or backward. Adjust text size as needed for ease in reading .
To reduce glare, place your monitor perpendicular to a window, adjust or add window blinds, and reduce interior lighting to lower glare and reflections. Use a task light that shines only on your paper .
