Patent ID: 8414170

Claim:
Method for manufacturing a batch comprising at least sixteen headlight lenses for a motor vehicle headlight, wherein each headlight lens comprises a lens body made from transparent material and having an essentially planar, optically operative surface as well as a convexly curved, optically operative surface, the method comprising pressing a pre-form between a first mold for pressing the convexly curved, optically operative surface and a second mold for pressing the essentially planar, optically operative surface, which second mold comprises a first mold section and an annular second mold section enclosing the first mold section, wherein due to the pressing a headlight lens of the batch is formed, the headlight lens having an integrally formed lens edge, wherein, by means of an offset depending on a 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 a region of the offset, and wherein a height of a step of a headlight lens of the batch differs by more than 0.05 mm from a height of a step of at least one further headlight lens of the batch.
