There are so many different filters out there, how should I choose a glass screen filter?
Our first advice is to make certain you buy a product that offers quality glass with anti-reflection and conductive coatings. Anti-reflection and conductive coatings on glass are manufactured using very expensive and sophisticated equipment and require optically flat glass. The cost of doing this means that the user must pay a little more but we believe it is worth it. Try to avoid buying the very inexpensive filters made from coloured glass, which some dealers give free with the purchase of a computer system. If the free filter is only coloured glass, ask the dealer to upgrade it to a quality filter with anti-reflection & anti-radiation coatings. Filter transmission is really a personal choice. People working with monochrome displays may be able to use a low (30% – 35%) transmission filter with its high contrast enhancement. But as more computer users migrate to using colour monitors with positive displays, we now recommend a fairly high transmission filter, 50% – 60% so that contrast
