The Polaroid Corporation has developed a filter to reduce the reflections and glare from the screen of a computer terminal. The filter is a transparent flexible sheet which is fastened to the terminal with four Velcro self-adhesive mounts designed to attach to the bezel surrounding the terminal's screen. The filter acts as a bight trap. Room bight passing through the filter to reflect from the screen is absorbed on its way back out so that the terminal operator sees only the bight of the screen display itself. This can be quite an advantage for people who spend several hours a day at a terminal. The product is presently available only from Polaroid's Polarizer Division at 1 Upland Road, Norwood, MA 02062. The cost per filter is approximately $100.
