ABSTRACT:
A method and apparatus for forming on-site tinted and coated optical elements from a mold having a polymer release layer; an optical coating, such as an anti-reflective coating; a coupling agent layer to bind to the optical coating and having unreacted chemical groups; and a hard coat layer having unreacted chemical groups. The hard coat may be tinted with dyes that are standard in the art. The mold can be shipped to a lab that prepares optical elements, such as ophthalmic lenses, after the coupling agent layer is added or after the hard coat layer, optionally tinted, is added. When using the mold with a lens resin having unreacted chemical groups, the coupling agent layer, hard coat layer, optionally tinted, and optical element all crosslink as the optical element is cured to form, on-site, a durable and stable lens with chemically bound optical coatings.
