Computer Monitor Eye Strain
The trend in computer screens is to replace the box type
Appropriate positioning of your monitor screen will cut back on unwanted exertion, and bad positioning, plus other possible health problems like exhaustion, eyestrain and related disorders like itching and styes.
Eyestrain, neck and back pain can be significantly reduced by proper selection of the monitor (or flat screen). The screen should be positioned in proper relation to other components like the keyboard, desk, and chair.
While using the computer monitor, ensure the following:
The screen is in front of you and at least 20 inches (45 centimeters) away.
The screen should not be more than 40 inches (100 centimeters) away.
Ultimate computer screen size is between 15 to 20 inches, (about 37 to 50 centimeters) measured diagonally. If the screen is very small, you’ll find it hard to read the characters. If the screen is very large, you may require too much space.
The ideal position is to have the screen directly in front of you. But, if that is not possible, the maximum ’off centering’ recommended is 35 degrees to the left or right of you. That’s approximately…not very much!
The top line of the computer monitor screen should be at or below your eye level. If necessary raise your chair a little, so that your line of sight is also raised. (However if you do this, make sure your feet still get good support, and your thighs can move freely under the desk.)
Computer monitor should not be placed above or on top of other equipment like a CPU (central processing unit) or a surge protector. The screen would be then higher than your eyes. That might well increase strain on your eyes, neck, and back.
If your work is chiefly involved with printed matter, it is better to place the computer monitor a little to the side, with the documents on a stand just in front of you. There should not be too much distance between the monitor and the printed matter.
The screen should be placed at right angles to windows, so avoiding irritating reflections.

Do not tilt computer monitors sharply either toward or away from you as the objects on the screen may appear distorted making them hard to view. Also, if the monitor is tilted back, there are chances of the overhead lights creating glare on the monitor, and a tilted or propped monitor may become unstable and fall over. You can tilt the computer monitor screen slightly – somewhere between 10 to 20 degrees – so that it is perpendicular to your line of sight. Always ensure that the angle and tilt of the screen can be adjusted without much effort.
For anything other than minor screen adjustment, it is better to have the computer monitor sitting on a riser/swivel stand, available from any good computer accessory store, on or offline. To avoid glare, make use of a glare screen, available again from any suitable source of computer accessories…
Get your screen setup right and you’ve taken a big step towards healthy computing!
