Adjustment of spectacle lens in frame - having frame details called from memory to provide graphics pattern print

摘要

The lens of spectacles are adjusted and controlled relative to the frame using information stored in a digital computer. In particular the frame data is stored as contours in the system and can be accessed to produce a printed copy, using a laser printer, daisy wheel or similar device. The printed pattern can also contain all reference data relating to the customer requirements. The pattern may then be compared with the glass lens to provide correct positioning and location. ADVANTAGE - Improved control of glass lens and frame.
