Improper placement of the computer monitor can lead to headaches, neck strains and back strains. Most experts agree that the computer monitor should be placed in front of the user, not to the side. The optimum height for your computer terminal should be such that the top of the screen is at eye level. If you type from copy, the copy should be the same distance as the monitor. Proper placement of the computer monitor can help avoid potential problems with the neck, back and eyes.
Glare is another problem involving the computer monitor.
Back lighting, overhead lighting, natural and unnatural lighting reflecting on the computer screen cause glare. To minimize glare, place the terminal such that the screen does not reflect overhead lights or outside glare from windows. Glare makes it hard to concentrate on the work at hand, which can lead to eyestrain and headaches. Another common injury with the computer workstation occurs with the back, neck and legs. Poor posture or poor support usually causes these type injuries.
