Abstract
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, and calculating new spectacle rim frame data expressed in the principal axes of inertia of the measured shape of the rim of the spectacle frame.
