Computers
If you use PCs, you are staring at that PC screen a lot. Therefore you need a correct screen setup as soon as possible,or your eyes,neck, shoulders and the rest of your body will suffer.
The trend in computer screens is to replace the box type computer monitor with a flat screen, saving weight space and power. However all the following tips apply equally to both types.
Suitable 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 considerably 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.

The screen should not be more than 40 inches (100 centimetres) away.
Ideal computer screen size is between 15 to 20 inches, (about 37 to 50 centimetres) measured diagonally.If the screen is very small, you?ll find it difficult to read the characters,while with a large screen,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 ?offcentering? recommended is 35 degrees to the left or right of you. Thats 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 monitors 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.
The screen should be placed at right angles to windows, so avoiding irritating reflections.
