Height
Position the monitor so that the top of the screen is slightly below your eye level when you sit at your workstation.
Orientation
Choose a position that gives the least reflection form lights and windows, usually at a right angle to any windows. Position the monitor directly in front of you so that you do not have to twist your body. Tilt the monitor to a comfortable viewing angle.
Working Practices
Rest
Take regular breaks. Vary your posture, and stand up and stretch occasionally, as prolonged use of computer workstations can be tiring.
Back
Sit back in the chair and use the backrest.
Hands
Use a light touches on the keyboard, keeping your hands and fingers relaxed. Allow a space in front of the keyboard to rest your wrists when not typing. Consider using a wrist pad.
Eyesight
Working with monitors, in common with any prolonged close work, can be visually demanding. Look away from the screen, periodically and have your eyesight checked regularly.
Screen settings
Set the screen brightness and contrast to a comfortable level. You may have to adjust this as the lighting changes during the day. Many application programs let you select color combinations, which can help you to view in comfort.
