摘要： This invention is directed to a method for heat treating a sheet of a potentially photochromic glass to cause the growth of silver halide crystals therein which impart photochromic properties thereto, wherein the heat treated sheet will be essentially free from thermal deformation and surface defects, and the photochromic properties exhibited therein will be essentially uniform across the area of the sheet. The method involves first placing a sheet of potentially photochromic glass on top of a sheet of carrier glass that exhibits a softening point at least 50.degree. C. higher than the temperature at which the potentially photochromic glass will be heat treated, and thereafter subjecting the stacked sheets to the heat treatment temperature desired for growing silver halide crystals in the glass.

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： A method of producing a glass-plastic, laminated, ophthalmic lens structure in a continuous operation. A thin, flexible, plastic adhesive layer is applied to a glass element to form a composite body that is inserted in a cylindrical gasket in such manner as to fit snugly and be sealed from the ambient. A monomeric formulation is flowed onto the adhesive layer and cured to form a laminated lens blank.
