An eye comfort device for optically adjusting the focal distance for screen viewing of a video display comprising a transparent plate constituting a lens with a diopter vergence value in the range of from 0.4 to 0.8 diopters and preferably from 0.5 to 0.6 diopters. The plate contains a quantity of a UV absorbent rose, magenta or pink tint or colorant sufficient to block at least 80 percent of UV transmissions within the range of from 300 to 360 nm. The preferred plate composition is a substantially transparent organic polymer containing, in addition to the magenta tint, a quantity of a UV absorbent sufficient to block at least 90 percent of UV transmissions below 400 nm.
