  • Patent number: 9974435
    Abstract: A quality control method for optometric measurements includes the following steps: (a) recording, via computer, a first record (14) that includes at least one first value of a first identifier (12), enabling identification of a glasses wearer (1), and at least one other value of another identifier (13) enabling identification of an optometric apparatus (15) on a first optometric measuring site (10); (b) carrying out at least one optometric measurement (16) of the wearer; (c) sending, to a second site (20), a digital measurement data set (18) including the optometric measurement result from step (b), the digital data set being linked, via computer, to the first record; and (d) digitally processing the optometric measurement result from the first record (14) on the basis of a digital data reference system (45) and the values of the respective identifiers of the glasses wearer and the optometric apparatus of the first record.

  • Patent number: 9703122
    Abstract: A method for determining at least one value of a customization parameter for a visual compensation device includes the following steps: a) a user (1) equipped with an electronic terminal (2) captures at least one image or video sequence; b) telecommunicating the at least one image to a remote-support center (22); c) processing the at least one image in order to derive therefrom an instruction to correct or validate the captured image or video sequence; d) telecommunicating the correction or validation instruction from the remote-assistance center (22) to the terminal (2) of the user (1); e) displaying or emitting an audio or video message using the terminal; f) repeating the preceding steps until a validated image or video sequence is obtained; g) determining a value of the at least one customization parameter.

  • Patent number: 9625743
    Abstract: A method of preparing an ophthalmic lens (20) for mounting in an eyeglass frame, the ophthalmic lens including a memory mark (28) that is situated on one of its ophthalmic faces (22) and that forms a code storing in digital form at least one item of information relating to a mechanical, geometrical, or optical characteristic of the ophthalmic lens. The method includes three steps: a) acquiring a raw image of at least a portion of the optical face of the ophthalmic lens on which an image of the memory mark appears; b) processing the raw image acquired in step a) in order to decode the information stored in the code; and c) centering and then shaping the ophthalmic lens as a function of the information decoded in step b).
