Abstract
This study evaluated six anti-glare filters for video display terminals. Subjective evaluations were made of the brightness, sharpness, contrast, color, glare and preference for each filter, as well as objective measurements of luminance, MTFA, contrast and glare. Overall, participants preferred anti-reflection coated, circular polarizer and nylon mesh filters to an etched plastic filter and to no filter. Subjective ratings of color, glare, and sharpness were found to contribute most to ratings of preference. Subjective and objective ratings of brightness, contrast, glare and sharpness were found to be moderately correlated. The focus of this work was to understand the relationship between certain physical variables and subjective measures of the effects of anti-glare technologies.
