Patent ID: 7997957

Claim:
A process for edging an optical lens comprising: a) providing an optical lens having a convex surface, the convex surface being provided with an anti-smudge topcoat having a surface energy of 14 mJ/m 2 or less rendering the optical lens inappropriate for edging; b) pre-treating the anti-smudge topcoat on the convex surface of the optical lens with an alkanol under a mechanical stress and drying the alkanol thereby rendering the optical lens appropriate for edging; c) fixing a mounting element on the convex surface of the optical lens with an adhesive pad adhering both to the mounting element and the convex surface of the optical lens to form a mounting element/optical lens assembly; d) placing the mounting element/optical lens assembly in a grinding machine so that the optical lens is firmly maintained; and e) edging the optical lens to the intended size and shape; wherein the optical lens is conformed to the size and shape of a lens frame into which the optical lens is to be accommodated wherein the anti-smudge topcoat has a surface energy of 14 mJ/m 2 or less after steps (b) and (e) have been performed.
