Abstract
A method of processing an unfinished optical lens member having a finished surface with a center reference point, and first and second surfaces, includes providing contour data defining the contour of the first surface in a finished cut state, the maximum distance between two points of the contour defined by C; determining, an optical reference point of the first surface with respect to the contour, the optical reference point corresponding to a user's line of sight in the finished cut state, the maximum distance between the optical reference point and the contour defined by M, providing a first surface dataset defining the second surface with respect to the optical reference point; and providing an unfinished optical lens member having a minimum distance Rbetween the center reference point and the boundary of the unfinished lens member such that 2 R≧Cand R<M.
