    Abstract: A composition adapted for use in an in-situ coating process for coating an optical surface for ophthalmic applications. A coating composition according to the present invention includes at least one multifunctional acrylate compound which is cured onto a heated surface with controlled coating distribution in an ophthalmic injection mold. For example, the composition may include an acrylic base cured with an initiator, e.g., t-butyl perbenzoate, and may further include at least one catalyst and at least one metal salt. An acrylic base according to the present invention may include a combination of monofunctional and/or multifunctional acrylate and/or methacrylate compounds.

    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.
