Computers and Lighting

The presence of computers in libraries has greatly impacted lighting issues within library environments. As the library becomes more reliant on information existing primarily or solely in digital form, it is increasingly important to understand the role played in library atmospherics by considered uniformity in comfort levels and by efficiency in use of lighting levels.

Generally speaking, when people are working on computers their eyes move from the screen, to the background and to adjacent visual attractions. Each time the eye moves, it adjusts to the new lighting level. If the degree of adaptation between visual tasks is too great, eye strain, fatigue and stress result. Similarly, a significant cause of eye strain for computer users is reflected light from poorly-placed light fixtures on glass screens. Glare and brightness ratios provide guidelines for lighting schemes within libraries to minimise eye strain. Considering these ratios in balancing different light sources can be complicated considering a library's various uses, from computer-screen use and microfiche, to reading and browsing, but is important in creating a productive and safe library atmosphere for all patrons.

Famous quotes containing the word lighting:

    No one after lighting a lamp puts it under the bushel basket, but on the lampstand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father in heaven.
    Bible: New Testament, Matthew 5:15,16.
