  • Apparatus and Method for Precision Coating of Ophthalmic Lenses with Photochromic Coatings
    Publication number: 20190291128
    Abstract: A method of manufacturing an optical article (10) includes supplying a first coating composition (A) and supplying one or more additional coating compositions (B) to an ultrasonic discharge nozzle (102) of a coating apparatus (100). At least one of the first coating composition (A) and the one or more additional coating compositions (B) is a photochromic coating composition. The method includes mixing the first coating composition and the one or more additional coating compositions at the ultrasonic discharge nozzle (102) of the coating apparatus (100), and applying the mixture (C) of the first coating composition (A) and the one or more additional coating compositions (B) to at least a portion of the optical article (10) so as to provide a pattern (24) on the optical article upon exposure to actinic radiation.

  • Multilayer photochromic articles
    Patent number: 10423061
    Abstract: A multilayer photochromic article can include a photochromic substrate, which may include a first photochromic layer defining a surface of the substrate, and a second photochromic layer positioned between the surface of the photochromic substrate and a source of actinic radiation, and in which the photochromic substrate and the second photochromic layer are selected such that the fade half-life of the photochromic substrate or the half-life of the first photochromic layer defining the surface of the substrate are greater than the fade half-life of the second photochromic layer.
