Abstract: This method for determining specification parameters used to manufacture an optical article includes steps of: training at least one neural network to predict the specification parameters, by using a training data set including a plurality of training prescription parameters and corresponding training specification parameters; and predicting specification parameters of the optical article by the at least one neural network, from prescription parameters relating to the optical article, on the basis of the training.

Abstract: 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.

Abstract: This disclosure includes methods and systems for producing ophthalmic lenses. Some methods include identifying a plurality of zones within a spatial representation of a lens blank, selecting, for each of the zones, one or more parameters for producing the lens, and producing the lens by removing material from the lens blank according to the one or more parameters of each of the zones.

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 diamete

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.
