computer ergonomics

With regard to the monitor, one must take in to consideration how the placement and maintenance of the monitor can effect both the eyes and the musculoskeletal system. The following suggestions can help prevent the development of eye strain, neck pain and shoulder fatigue while using your computer workstation:

• Make sure the surface of the viewing screen is clean.
• Adjust brightness and contrast to optimum comfort.
• Position the monitor directly in front of user to avoid excessive twisting of the neck.
• Position the monitor approx. 20-26 inches (arm's length) from user.
• Tilt top of the monitor back 10 to 20 degrees.
• Position monitors at right angles from windows to reduce glare.
• Position monitors away from direct lighting which creates excessive glare or use a glare filter over the monitor to reduce glare.
• The top of the viewing screen should be at eye level when the user is sitting in an upright position (NOTE: Bifocal wearers may need to lower monitor a couple of inches).http://www.youtube.com/watch?v=KiAR7L-LjhU
