METHOD FOR AUDITING IN 'REAL-TIME' AND IN-LINE THE QUALITY OF A DIGITAL OPHTHALMIC LENS MANUFACTURING PROCESS

摘要

The present invention relates to a method for modelling and quantitatively evaluating an overall quality level of an ophthalmic lens, said lens having specific "lens" and environment parameters, and being produced by a digital ophthalmic lens manufacturing process. A method for performing a real-time in-line quality audit of a freeform production line is also provided, using a quality score of the manufacturing process, based on a standardisation of the overall quality level calculated digitally on each lens produced, relative to the expected value of said quality level in the context of normal production, possibly affected by systematic differences evaluated independently.
