ABSTRACT:
An apparatus for blocking an ophthalmic lens blank for working the lens includes an alignment station for supporting and aligning the lens blank relative to a target image and a transport means for moving the lens from the alignment station to a blocking station while maintaining lens orientation. The blocking station includes a support for a lens block, support for the lens, and a mechanism for injecting heated liquid bonding material between lens and block which solidifies on cooling to join the lens and block.
