Abstract:
The invention relates to a method for producing an optical lens element, more particularly for illumination purposes, more particularly for producing a headlamp lens for a vehicle headlamp, more particularly for a motor vehicle headlamp, according to which method liquid, transparent, more particularly amorphous, synthetic material is placed into a lower mold. The synthetic material is then pressed between the lower mold and an upper mold by putting the lower mold and the upper mold together. The lower mold and the upper mold are then separated. Further liquid, transparent, more particularly amorphous, synthetic material is then added to the pressed synthetic material and the synthetic material is then pressed, more particularly precision pressed, to form the lens element.
