摘要： Colored photochromic ophthalmic lenses are produced by combining a photochromic cap element having an integrally colored back surface with an ophthalmic crown base element having a prescription-ground back surface, the cap back and base element front surfaces having been finished to a matching standard base curvature, thus providing a cemented assembly exhibiting a selected combination of prescribed vision-correcting and light filtering properties.

摘要： Silver halide-containing photochromic glasses are rendered optically anisotropic by darkening with actinic radiation and irradiating with linearly polarized bleaching light. A photochromic glass so treated will be optically isotropic when it returns to the clear state, but may again become optically anisotropic when redarkened. Color adaptation results when darkened silver halide-containing photochromic glasses are irradiated with colored optical bleaching light.

摘要： Light-transmitting polycrystalline member consists essentially of magnesium oxide with from 0.3% to 4% by weight of dysprosium oxide dispersed therein. The density of the member approximates theoretical. To make the member, the desired weight percent of dysprosium oxide powder is dispersed in magnesium oxide powder and the mixture is first isostatically pressed to form a green compact. The compact is then sintered in oxygen at from about 1,800*C to about 2,000*C for at least about 3 hours.

The inventive method comprises four general steps:(a) a batch for a glass containing silver and at least one halide selected from the group of chloride, bromide, and iodide is melted and the melt shaped into a glass body of a desired geometry;(b) the glass body is subjected to a heat treatment at least above the strain point but not in excess of 50.degree. C. above the softening point of the glass for a period of time adequate to cause the generation of AgCl and/or AgBr and/or AgI particles therein, said particles ranging in size between 200-5000 .ANG.;(c) the glass body is elongated under stress at temperatures above the annealing point, but below that where said glass exhibits a viscosity of about 10.sup.8 poises, such that the particles are elongated to an aspect ratio of at least 5:1; and(d) the elongated glass body is exposed to a reducing environment at temperatures between 250.degree. C. and about 25.degree. above the annealing point of the glass to reduce the silver halide particles in the glass to metallic silver which is deposited in and/or upon the elongated particles.
