Method for ordering a spectacle lens and associated system

A method for ordering a spectacle lens for a wearer, said method comprising:

• capturing, by a camera, at least one picture showing at least a portion of a face of said wearer wearing a selected spectacle frame, the at least one captured picture being sufficient so that a position of said selected spectacle frame on the wearer's face is extractable from said at least one captured picture;
• determining, by processing circuitry, a frame shape of the selected spectacle frame by:
• reading from within the at least one captured picture, a barcode tag having data storage capacity appearing within the at least one captured picture, the barcode tag being encoded with at least information describing a three dimensional shape of the selected spectacle frame;
• responsive to the reading, directly extracting at least the information describing the three dimensional shape from the barcode tag without connecting to a database;
• processing, by the processing circuitry, said at least one captured picture and obtaining, by the processing circuitry, the position of said selected spectacle frame on the wearer's face using the three dimensional shape of the selected spectacle frame extracted from the at least one captured picture;
• and
• selecting, by a server, said spectacle lens complying with said selected spectacle frame and said three dimensional shape of said selected spectacle frame, said position of said selected spectacle frame on the wearer's face, and wearer data, wherein said wearer data comprises at least a prescription for the wearer.
