Abstract: A method of preparing a lens blank for a further operation of surfacing to transform the lens blank into a surfaced lens for further transformation into a lens having a lens shape, the operation of surfacing including processing the lens blank so that the surfaced lens exhibits a crib diameter, the method being implemented using a processing module and comprising: based on input data (ID) which define the lens shape, defining a temporary crib diameter (Dtemp) so that said temporary crib diameter satisfies a set of constraints which includes at least: a first constraint whereby the temporary crib diameter (Dtemp) is large enough for the surfaced lens having said temporary crib diameter to be suitable to be processed into said lens, a second constraint whereby the temporary crib diameter is large enough for the surfaced lens having said temporary crib diameter to include a plurality of reference points defined on the lens blank and which together identify an optical center of the lens, choosing the crib diameter as a function of the temporary crib diameter (Dtemp), said choosing the crib diameter being configured so that, when a step cribbing configuration is destined to be applied to the operation of surfacing, said crib diameter is chosen among at least one predetermined discrete value (Vali).

Abstract: Systems, computer-implemented methods, and computer-readable storage media that execute, are configured to execute, or store instructions that enable modification of optical manufacturing data, including a computer-implemented method for modifying optical manufacturing data. The method includes receiving the optical manufacturing data associated with an optical job and modifying the optical manufacturing data using manufacturing logic to generate modified optical manufacturing data. The modified optical manufacturing data is then used in the manufacturing process of the optical job.

Abstract: A real-time calculation system capable of computing the industrial optical performance and yields of a prescription laboratory is disclosed. The system uses statistical analysis to determine the compensation factors that can be applied to given products, Semi-Finish, materials, or lens designs to increase the lab yields. Using a monitoring and configuration system, the user tracks the evolution of the laboratory's performance and identifies areas in which yields are impacted. The user defines how the calculation system will optimize the laboratory's performance, such as by defining how the compensation factors will be calculated and applied.
