  • Composition for transparent antistatic coating
    Patent number: 9778399
    Abstract: The present invention relates to a curable composition providing upon curing a transparent antistatic coating comprising a silica organosol, a salt comprising an alkali cation and a Bronsted acid. The invention further relates to optical articles comprising a substrate at least partially coated with a transparent antistatic coating formed by depositing onto substrate and curing the above curable composition. The obtained optical articles exhibit enhanced antistatic properties, high optical transparency, low haze and good mechanical properties, in particular a good abrasion resistance.
    Type: Grant

  • Method for adding a thermoset overmold layer to a lens within a mold
    Patent number: 7820082
    Abstract: A method and coating used to prepare a photochromically-enabled bifocal ophthalmic lens. The method and equipment includes injection molding a single vision lens, for example, from polycarbonate. The clamp opens vertically and the top insert is exchanged for a bifocal mold having a base curve similar to the single vision lens. The thermoset coating includes compounds from several acrylate classes, and is applied to the single vision lens. The coating may include a photochromic dye. The coating is also formulated to receive a photochromic solution through an imbibition process.
