Abstract
Disclosed is a method of forming a coated optical element. The method includes providing a mould assembly having opposed mould sections and applying a UV-curable hard coat monomer composition to the casting face of at least one of the mould sections to form a hard coat monomer layer. The hard coat layer is irradiated with UV radiation under conditions to form a partially cured hard coat layer. The assembled mould is filled with a high index optical element precursor material the optical element precursor material and the partially cured hard coat layer are cured to form a high index optical element having a hard coat.
