Abstract: The invention relates to a method of processing an unfinished optical lens member for manufacture of an optical lens from the unfinished optical lens member, the unfinished optical lens member being provided with a finished surface having a geometrical centre reference point, the optical lens having a first and a second surface, said first surface being comprised in the finished surface of the unfinished optical lens member, the method comprising: providing contour data defining the contour of the first surface of the optical lens in a finished cut state, the maximum distance between two points of the contour being defined by a distance Cmax; determining, an optical reference point of the first surface of the optical lens with respect to the contour, said optical reference point corresponding to the line of sight of a user of the optical lens in the finished cut state, the maximum distance between the optical reference point and the contour being defined by a distance Mmax, providing a first surface dataset defining the second surface with respect to the optical reference point; providing an unfinished optical lens member having a minimum distance RSF between the geometrical centre reference point and the boundary of the unfinished optical lens member such that 2 RSF= Cmax and RSF
