Abstract:

A method of blocking ophthalmic lenses for edging comprises providing an ophthalmic lens having first and second surfaces, providing a first block for securing against the first lens surface and a second block for securing against the second lens surface. The method then includes placing an adhesive layer on the first block, placing a film having cling properties between the adhesive layer and the first lens surface, and urging the first block toward the first lens surface and the second block toward the second lens surface. The film having cling properties provides sufficient bonding force between the adhesive layer and the first lens surface to prevent the ophthalmic lens from slipping in the blocks during edging thereof.
