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.
