Abstract
A lens blocker assembly has a first support table moveable in a first direction. A second support is carried by the first support and is moveable in a second direction, with the second direction being angularly disposed relative to the first direction. Variable output drives are operably associated with the supports for selectively moving the supports in the associated directions. A lens block applicator is operably associated with the second support for applying a lens block to a lens blank disposed on the second support.
