Anti-glare filters are designed to help relieve eyestrain, fatigue, headaches and the stress associated with continued viewing of computer monitors by reducing glare. Anti-radiation filters help eliminate exposure to radiation emissions. Some products provide both anti-glare and radiation protection. These types of products can also be found at office supply stores.
Some filters are designed to hang over or attach to the top of the monitor. Other filters are made of a thin film that attaches directly to the screen surface.
