Reducing Eye and Back Strain During Computer Usage
Screen Position: 20 degrees down from your line of sight is where the top of the screen should be, the bottom of the screen should be 20 degrees below that. The screen should be positioned between 20-28 inches away from your eyes.
Lighting: The ambient room light should be 3x brighter than the screen background. Eliminate any glare sources hitting your screen or your eyes (consider blinds on windows, grates on overhead lights, visors or anti-glare screens* on your monitor)
*AOA approved anti-glare, antistatic, anti-radiation properties
Characters: Good contrast is important. Black letters on a white background provides the best contrast. Font size should be about 12 point, which makes the characters about 2.3-2.5 mm high. There should be about 80 characters per line, 25 lines per screen.
Screen Flicker and Swim: This isn’t a problem with the new LCD screens, but CRT screens should have the refresh rate set at >60 Hz for normal polarity, and >80 Hz for reverse polarity. This reduces notable flicker and light variation for the eye to constantly adjust to.
Eliminate Dry Eyes: Drink 6-8 glasses of water per day. Consciously blink every time you think of it. Use artificial tears periodically throughout the day.
Visual Breaks: Take a visual break every 15-20 minutes by looking at an object at least 20 feet away for at least 20 seconds, the longer the better. A 15 min break from the computer to perform a different task at a different distance every two hours is ideal.
Ergonomics: An adjustable chair with lumbar support is ideal. Your trunk should be straight but inclined forward 20 degrees. Your feet should be flat on the floor or flat on a footrest. Your thighs should be horizontal on your chair with the lower leg vertical. Wrists should be straight with the forearm horizontal and upper arm vertical. Your screen keyboard and source document should be in the same viewing plane at a depressed angle.

What’s KTS up to?
KTS recently installed and configured a secure wireless solution for a local health center utilizing Cisco wireless access points. Nurses can now utilize tablet PCs with wireless connections to roam patient rooms, keeping patient’s medication information up-to-date in real-time. Utilizing WDS (wireless distribution system) technology, nurses can roam the entire health center without connectivity interruptions (disconnects) because of the multiple access points that are smart enough to hand off the wireless connection to another access point with greater strength.
