  • Optical article comprising a substrate with embedded particles for light transmission enhancement
    Patent number: 11852784
    Abstract: The invention relates to an optical article having a substrate made of an optical material comprising a polymer matrix and an improved light transmission in the visible range. The substrate comprises an external layer in which particles are embedded into the polymer matrix, the refractive index of the particles Rp being lower than the refractive index of the polymer matrix Rs.
    Type: Grant
    Filed: August 8, 2018
    Date of Patent: December 26, 2023
    Assignee: Essilor International
    Inventors: Pierre Fromentin, Hélène Maury, Francisco De Ayguavives, Thanisararat Saleesung
  • Optical Article Comprising a Substrate with Embedded Particles for Abrasion and/or Scratch Resistance Enchancement
    Publication number: 20200241174
    Abstract: The invention relates to an optical article having a substrate made of an optical material comprising a polymer matrix and an improved abrasion and/or scratch resistance. The substrate comprises an external layer in which particles functionalized by a silane coupling agent are embedded into the polymer matrix, the Bayer value of said substrate determined in accordance with the ASTM F735-81 standard being at least 30% greater than the Bayer value of the same substrate with no embedded particles.
