摘要： An optically activated bleaching process effective to permanently modify the color of surface-colored silver halide-containing photochromic glasses produced by thermal reduction treatments is described, wherein the glass is coincidentally exposed, for an effective time interval, to (i) a source of high energy light and (ii) a heat source. The process reduces the relatively strong absorption peaks characteristic of the initially colored glass, resulting in a permanent bleached appearance.

摘要： The instant invention is concerned with a method for producing shades of a tint in a photochromic glass, the hue of which will be essentially permanent even after subjecting the glass to temperatures up to about the strain point of the glass. Silver halide crystals constitute the photochromic agents, the glass contains lead, and the method contemplates exposing such a glass to a gaseous reducing atmosphere at temperatures above the strain point of the glass to cause the reduction of silver ions to metallic silver and the reduction of lead ions to metallic lead which coats or alloys with the metallic silver.

摘要： This invention is concerned with producing glasses suitable for use as spectacle lenses for aphakics or for persons subject to photoretinitis or retinitis pigmentosa. The glasses exhibit near-zero transmittance of radiations having wavelengths shorter than a selected cutoff wavelength ranging about 440-550 nm and the transmittance of the remainder of the visible spectrum is adjusted through the glass demonstrating photochromic behavior. The inventive method contemplates exposing photochromic glass within a narrowly-defined composition range to a strongly-reducing atmosphere at temperatures between about 350.degree.-520.degree. C. for a period of time of at least 12 hours to develop an integral colored surface layer on the glass.
