LENS PROCESSING METHOD AND APPARATUS (Abstract of the Disclosure) A chucking method and apparatus for processing a lens blank in a manner requiring only a single mounting of the blank to an associated lens block. The lens block is mounted to the convex lens blank surface by a hot melt type of adhesive so as to extend outwardly thereof substantially coaxial with the lens blank frame center axis. The lens blank and lens block are releasably mounted in a chuck associated with lens surface generating apparatus such that the lens blank frame center axis and the tail stock of the generating apparatus are coaxial. The chuck includes means for selectively adjusting and rotating the lens blank relative to the tailstock for accommodating any desired decentration, axis setting and prism prescribed for the finished lens. Following generation of the desired optical characteristics in the lens blank, the blank and associated lens block are mounted and processed first in surface fining apparatus and then in peripheral edge contouring apparatus. In these operations, the lens blank frame center axis is disposed substantially coaxial with the associated apparatus tail stocks or chucks. An adaptor conveniently allows adjusting rotation of the lens blank about its frame center axis in the surface fining and polishing apparatus compatible to any degree of rotation accommodated during surface generation. Following lens blank edge contouring, the lens block is removed from mounted association with the finished optical lens.
