The invention relates to a method for producing an optical lens element (), particularly for illumination purposes, particularly for producing a headlight lens () for a vehicle headlight, particularly for a motor vehicle headlight (), wherein a blank () made of a transparent plastic is shaped in an injection molding tool () by means of an injection molding method, and the blank () is subsequently pressed into the lens element () by means of a final shape mold (), particularly in a polished manner.

Method for producing an optical lens element, particularly a headlight lens for a motor vehicle headlight

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.

Method for manufacturing a headlight lens for a vehicle headlight

The invention relates to a headlight lens for a vehicle headlight comprising a light source, particularly for a motor vehicle headlight, wherein the headlight lens comprises a transparent lens body made of glass comprising a surface arranged to face the light source and a surface arranged to face away from the light source, and wherein the headlight lens comprises at least with respect to said surface arranged to face away from the light source a layer comprising an aluminum concentration which is higher than an aluminum concentration inside the lens body and/or a sodium concentration which is lower than a sodium concentration inside the lens body.
