A headlight lens is provided for a vehicle headlight. The headlight lens includes a lens body and a lens edge. The lens body has an operative surface that extends beyond the lens edge.

Production method for a headlight lens and headlight lens for a motor vehicle headlight

The present disclosure is directed to a method for manufacturing a batch of motor vehicle headlight lenses, each lens comprising a lens body and a convexly curved optically operative surface. The method comprising pressing a pre-form between a first mold and a second mold, which second mold comprises a first and second mold sections. An offset depending on the volume of the pre-form a step is pressed into the headlight lens between the second mold section and the first mold section, wherein the first mold section is set back with respect to the second mold section at least in the region of the offset, and wherein the height of a step of a headlight lens of the batch differs by more than 0.05 mm from the height of a step of at least one further headlight lens of the batch.

The invention relates to a headlight lens for a vehicle headlight, particularly for a motor vehicle headlight, wherein the headlight lens comprises a bright-molded lens body made of a transparent material, having a substantially plane optically effective surface and a convexly curved optically effective surface, wherein the headlight lens comprises a lens edge on the outside of the convexly curved optically effective surface, wherein the substantially plane optically effective surface, protrudes over the lends edge, or over part of the lens edge, in a stepped manner in the direction of an optical axis of the headlight lens.
