摘要：
The invention relates to a method for producing a headlamp lens (2) for a vehicle headlamp, in particular for a motor-vehicle headlamp (1), wherein the headlamp lens (2) comprises a transparent body (3) with an optically effective surface (5), which is in particular substantially planar and can be turned towards a light source (10), and an optically effective surface (4), which is in particular convex and can be turned away from the light source (10), wherein the gradient of a light-dark boundary (25) projected by the headlamp lens (2) or a further headlamp lens is measured, and wherein a light diffusing structure (35) is produced in the transparent body (3) in accordance with the measured gradient.
