All of these things create a hostile environment for the eyes. The easiest thing to do is reposition the monitor. To cut down on particle emission wipe down the screen daily with anti-static spray. If you have to read a source document while typing, use a document holder and position it right next to the monitor at the same height. Although a document should be in a well lighted area for optimal reading, a monitor should not.
Screen glare is caused by both natural and artificial lighting reflecting off the screen surface.
Though most offices are illuminated with harsh fluorescent lighting, this is unsuitable for computer users because it creates a lot of overhead glare and harsh shadows. Ideally, a monitor should be in a softly lit, dim area. If this is not possible, the monitor should be positioned between rows of overhead lights instead of directly underneath them, and a light diffuser should be used. If the sources of glare can not be eliminated, it might be necessary to buy a hood or a glare guard for the monitor. Glare guards, however, should be considered a last resort because many of them reduce glare at the cost of screen clarity.
