Abstract
A process for edging an optical lens for conforming the optical lens to the size and shape of a lens frame into which the optical lens is to be accommodated, said process comprising: a) providing an optical lens having a convex surface, the convex surface being provided with an anti-smudge topcoat rendering the optical lens inappropriate for edging; b) fixing a mounting element on the convex surface of the optical lens, preferably on its center, by means of 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; c) placing the mounting element/optical lens assembly in a grinding machine so that the optical lens is firmly maintained; and d) edging the optical lens to the intended size and shape, wherein, prior to step (b) of fixing the mounting element, the anti-smudge topcoat on the convex surface of the optical lens is pre-treated with a solvent selected from the group consisting of alkanols and dialkylketones under a mechanical stress.
