Abstract
The invention concerns a method for producing an optical lens element, in particular for illumination purposes, in particular for producing a headlight lens for a vehicle headlight, in particular for a motor vehicle headlight (), wherein a pre-lens element () is injection molded using at least one mold by heating liquefied transparent plastic, wherein the pre-lens element () being cooled in such a way that the plastic solidifies, and at least one optically effective surface of the pre-lens element () then being heated in such a way that the plastic on the optically effective surface can be shaped, in particular up to a depth of not more than 1000 micrometers, wherein the pre-lens element () is pressed with the optically effective surface in a final contour mold to form the lens element.
