ABSTRACT:
Methods for edging optical articles comprising two main faces, at least one of which being coated with an outermost layer comprising fixing the optical article to a chuck with a holding pad that adheres to both the optical article and the chuck, wherein the surface of the holding pad contacting the optical comprises an adhesive material; and edging the optical article with an edging device; wherein prior to fixing the optical article to the chuck, at least one temporary layer of an organic material is formed onto said outermost layer of the optical article, the organic material of the temporary layer comprising at least one organic compound having a fluorinated functional moiety and at least one linking functional moiety capable of establishing at least one intermolecular bond or interaction with the adhesive material of the holding pad. Optical articles obtained via these methods.
