Abstract: A method for determining a semi-finished lens blank, including the steps of: determining, for a given material, a set of faces (S1, S2, . . . Sn) to be defined for a line of ophthalmic lenses, each face (Si, Sj) being defined for a corresponding subset (SEi, SEj) of wearer data and/or frame data; determining, for each face (Si, Sj), a minimum thickness requirement (EnvSi, EnvSj) necessary to produce all the lenses of the corresponding subset (SEi, SEj); determining combinations of two faces (Si, Sj) to be paired; defining a “double-faced” semi-finished lens blank (SF(ij)) consisting of two paired defined faces (Si and Sj) and including the minimum thickness requirements (EnvSi and EnvSj) respectively determined for the faces, in a manner that allows producing all the lenses of the subsets (SEi and SEj) corresponding to said faces.

Abstract: A method for determining an electronic spectacle frame element of a spectacle frame, including providing electronic element data relating to an electronic element to be embodied in a spectacle frame element; providing predetermined spectacle frame element data related to at least one geometrical parameter of a predetermined spectacle frame element, corresponding to the wearer demand; defining a working electronic spectacle frame element including a working spectacle frame element and an electronic element embodied in the working spectacle frame element based on the electronic element data, modifying the working electronic spectacle frame element, and determining the electronic spectacle frame element by repeating the modifying step so as to minimize the difference between the geometrical parameters of the predetermined spectacle frame element and the working spectacle frame element.

Abstract: The disclosed embodiments provide an improved method for enabling consumers to identify and purchase a desired frame that is captured in an image. For example, in one embodiment, the disclosed embodiments include a frame recognition system that includes at least one processor for executing computer executable instructions for receiving an image; identifying a frame image from the image; performing image recognition using the frame image to identify a plurality of frames; retrieving merchant information corresponding to the plurality of frames; receiving merchant information associated with the plurality of frames; presenting the plurality of frames and the merchant information associated with the plurality of frames; receiving order information in response to a user ordering a frame from the plurality of frames; and processing the order information.
