A system and method for applying a finishing block (102, Fig 1) to a lens 24 includes an apparatus which displays an alignment pattern representing characteristics of the lens and includes a visual representation 47 of the allowable tolerance in the position of the optical center 43 of the lens and the prism of the lens. An imaging screen 18 is provided for imaging the alignment pattern and reference data 29, 30 applied to a surface of the lens. The lens is positioned in the apparatus with the pattern and the data aligned. With the lens in this position, a determination is made using the visual representation as to whether the lens is within the allowable tolerance. If this is the case, the apparatus automatically attaches the finishing block to the lens in registration with the reference data. |
