<p>A method for modifying spectacle frame shape data, comprising the steps of:
€¢ generating spectacle frame data by measuring the shape of a rim of a spectacle frame with a spectacle frame shape measuring apparatus,
€¢ determining the principal axes of inertia of the measured shape of the rim of the spectacle frame using the rim spectacle frame data,
€¢ calculating new spectacle rim frame data expressed in the principal axes of inertia of the measured shape of the rim of the spectacle frame.</p> |
