Use -- Optimum monitor distance from the eyes is between 18 and 24 inches. Closer distance magnifies possible eyestrain, and dust and radiation exposure.  The top of the screen should be at eye level, or not more than 15 degrees below eye level. If lower than this, the monitor should be raised by means of a monitor stand or other stable lift.  If the monitor offers a manual focus adjustment, use it frequently to ensure the image is as sharp as possible.  The electrical charges in monitors attract much dust. Clean the screen frequently to keep the image sharp. Eliminate or reduce screen glare by keeping direct light sources away from the screen. Use indirect lighting if possible. Don't position the monitor in front of a brighter light source. If glare can be reduced only through the use of an optional anti-glare attachment, make sure it has an AOA (American Optometric Association) Seal of Acceptance. A monitor that utilizes dark letters on a light background, or that offers this setup option, is preferable to reduce eyestrain. In building your monitor's "desktop" or creating a document, avoid using red or blue for either the background-where they tend to be brighter than the work document-or for the regular font (text) color-where they are less distinct.

Safety -- Monitors not only attract dust but repel it toward the face. Keeping the screen free of dust also minimizes potential allergic reactions. Monitors are a source of radiation. While some dangers thought to exist have been found to be minimal, others are still being studied. Radiation is most prevalent out the backs and sides of monitors. Workstations backing upon one another should be at least 48 inches apart. Workstations placed side-by-side should be at least 36 inches apart. For optimum radiation safety, turn off the monitor when not in use. On most newer workstations this can be done without shutting down the computer.
