摘要： An ophthalmic filter material having a photopic transmittance (Y.sub.P) higher than the scotopic transmittance (Y.sub.S), the ratio of Y.sub.P :Y.sub.S being in the range of 2.0-4.0, a dominant wavelength within the ranges of 580-605 nm and a color purity of 60-75% whereby colors perceived through the material approximate those of the scene being viewed. A method of producing such a filter material which comprises heating a photochromic glass lens in a reducing atmosphere for a time and at a temperature that is sufficient to impart the recited characteristics to the glass surface and that is equivalent to a flowing hydrogen atmosphere, or immersing a tintable plastic solution in a dye solution for a time sufficient to impart the recited characteristics.

摘要： This invention is directed to the production of glass articles transparent to visible radiation, but opaque to ultraviolet radiation, rendering them particularly suitable for protecting the wearer of such lenses from exposure to laser radiation in the ultraviolet regions of the electromagnetic spectrum. The method involves exposing silver halide-containing glass articles to flowing hydrogen in a heat chamber operating at 375.degree.-500.degree. C. for at least four hours to produce an integral reduced layer in at least one surface of the articles of sufficient depth to prevent the transmission of ultraviolet radiation through the articles.
