Trays, each containing either a spectacle frame and a pair of lenses to be preshaped, or a lens template, are taken to a VDU 3 with an IR bar code reading pen 3 min . Depending upon the response of a central computer 1 to data fed in by the pen 3 min and keyed in by an operator, the tray is then (A) routed directly to a lens edger unit 4, or (B and C) routed indirectly to the unit 4, via either (B) a frame encoder unit 6 which measures and encodes the internal dimensions of a > frame, or (C) a template encoder unit 7 which measures and encodes the external dimensions of the template. As each tray on route A or B moves towards the unit 4, an edger driving file particular to the frame in the tray is recalled by the computer 1 from a mass data store (2) and modified and the modified file held temporarily in a buffer store 5 until required by the unit 4.

Title
A method of and apparatus for dimensioning a lens to fit a spectacle frame.
