A method and associated implementing system eliminates much of the stress presently introduced by the bonding of ophthalmic lens blanks, or blanks to a holding device, namely a metal block. The method of attaching ophthalmic lens blanks to a blocking assembly comprises the steps of shaping a blocking assembly to take the shape of an ophthalmic lens blank surface of an ophthalmic lens, wherein the blocking assembly is not attached directly to the ophthalmic lens blank during shaping of the blocking assembly; and following the shaping of the blocking assembly, attaching the lens blank to the shaped blocking assembly.
