Abstract
Method implemented by computer for optimizing a set of optical lens blanks used to manufacture a set of optical lenses, each optical lens comprising first and second optical surfaces, the first and second optical surfaces being connected by a external periphery surface, the method comprising: a data providing step during which a set of data for every optical lens of the set of optical lenses is provided, the data comprising at least contour data representative of an external periphery surface of the optical lens, a first dataset representative of the first optical surface of the optical lens and a second dataset representative of the second optical surface of the optical lens; a supply cost function providing step during which a supply cost function is provided, the supply cost function being a function of the number of different optical lens blank comprised in the set of optical lens blanks.
