Method and apparatus for obtaining optical center lens, attaching lens to a lens holder, and producing lens

摘要

The present invention provides a method and apparatus for automatically and continuously conducting the layout analysis, the blocking (attachment) of an uncut lens to a lens holder, and the process of grinding an edge of three types of lenses, such as a single-vision lens, a progressing multifocal lens and a multifocal lens, utilizing a calculated approximation of the optical center of the uncut lens and by determining the position to which a lens holder should attach to the uncut lens.
