Abstract: The invention provides a machine for coating an optical article with an anti- soiling coating composition, comprising a vacuum chamber (8) configured to receive the optical article, a vacuum pump (20) connected to the vacuum chamber (8), a plasma generator (11) configured to carry out a vacuum plasma treatment of the optical article, an evaporation device (10) configured to carry out a vacuum evaporation treatment of the composition for depositing it on the optical article, a control unit (2) controlling the plasma generator for removing an initial outermost anti-soiling coating of the article, controlling the evaporation device for recoating the article with the anti-soiling coating composition, being configured to causes the vacuum pump (20) to suck gases from the chamber (8) during vacuum plasma treatment and being further configured to causes the vacuum pump (20) not to suck gases from the chamber (8) during vacuum evaporation treatment.

Abstract: The present invention provides a UV antireflective coating stack for ophthalmic lenses. The antireflective coating stack is deposited by sputtering, which lowers the reflectivity of the antireflective stack in the UV range and maintains low reflectivity in the visible range. The antireflective coating stack offers improved thermo-mechanical performance as compared to evaporation-based UV antireflective stacks.

Abstract: A method that includes providing a lens having a first side, a second side, and an anti-reflective or mirror coating on the first side; depositing a heat-curable coating on the second side of the lens; and heating the heat-curable coating without damaging the anti-reflective or mirror coating. Another method that includes providing a non-pure polycarbonate lens having a first side, a second side, and a first coating on the first side; depositing a heat-curable coating on the second side of the lens; and heating the heat-curable coating without damaging the first coating. Other methods are also disclosed.
