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.
