Guidelines for monitor placement and lighting
Eye-to-screen distance: at least 25", preferably more.
Vertical location: viewing area of the monitor between 15° and 50° below horizontal eye level.
Monitor tilt: top of the monitor slightly farther from the eyes than the bottom of the monitor.
Lighting: ceiling suspended, indirect lighting. Use blinds and shades to control outside light.
Screen colors: dark letters on a light background.
How do you set up a computer workstation? Do you buy monitor risers or remove the CPU from beneath the monitor. Will even lower monitor positions cause neck strain? Can you get away with tipping the monitor down to avoid glare or should you invest in indirect lighting? How about viewing distance? 16 inches? 25 inches? Or even farther? Does screen color make a difference? Is there any evidence that ergonomic workstations improve work performance?
This article suggests guidelines for monitor placement and lighting. They are based on the latest scientific research. Demonstrations illustrate the principles behind the recommendations.
Ergonomics seeks to adapt the work environment to the capabilities and limitations of the worker. The results should be increased productivity, user satisfaction, and reduced risk of injury.These guidelines are meant as such: guidelines. There are exceptions. The final criteria for judging the effectiveness of a visual environment is not how well it conforms to a set of rules, but rather how well it facilitates the ability of the worker to perform his or her work effectively and without injury.
