In a method of preparing a lens blank for a surfacing operation, the lens blank is fastened to a support with a base and a support material via which the lens blank is fastened. The support material has a circular periphery. The surfacing transforms the lens blank into a surfaced lens. The method includes: determining the surfaced lens shape based on input data; based on the surfaced lens shape, determining a maximum diameter of the support material shape based on a predetermined maximum thickness defining the maximum thickness of the support material allowed to be cut into during the surfacing of the lens blank; choosing a diameter for the support material shape ≤the maximum diameter for further fastening the lens blank to the support by forming the support material so the support material shape has a diameter corresponding to the chosen diameter.

Disclosed is a method of preparing an operation of surfacing of a lens blank to transform the lens blank into a generated lens having a predetermined prism corresponding to an inclination between a front surface and a back surface of the generated lens at least locally. The method includes: for a plurality of devices destined to interact with the lens blank during the operation of surfacing to manufacture the predetermined prism of the generated lens, attributing a priority order to each; based on the priority order, attributing to each device a prism portion which is zero or included in a respective range delimited by a respective minimum prism portion and a respective maximum prism portion, the prism portion representing contribution of the corresponding device to the prism of the generated lens, for further interaction of each device with the lens blank during the operation of surfacing.

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.

Distributed optical job and manufacturing computation systems and methods

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.
