    摘要: A fixed tint, photochromic glasses and sunglass lenses produced therefrom. The glasses have R2O—Al2O3—B2O3—SiO2 base compositions, contain silver chloride and bromide contents as photochromic constituents and 0.27-0.38% and 0.035-0.060%, both by weight percent, as glass colorants, the NiO:Co3O4 ratio being at least 6:1.

    摘要: An ophthalmic, protective, filter lens, and a method of producing such lens, the lens having a ratio of Z and Y tristimulus values between 0.25-0.40, a dominant wavelength between 570-580 nm. on a color mixture diagram, a sharp transmission drop between 450-500 nm. and a transmission not over 30% between 400-450 nm.
