The invention relates to a method for producing an optical lens element, in particular for illuminating purposes, in particular for producing a headlight lens for a vehicle headlight, in particular for a motor vehicle headlight. A preform made of a transparent plastic, which is amorphous in particular, is molded in an injection mold using an injection molding method. The preform is removed from the injection mold, in particular before the average temperature of the preform falls below the melting temperature of the plastic and/or the flow temperature of the plastic, and the preform is subsequently pressed into the lens element, in particular the blank, using a final contour mold.
