Abstract

The invention relates to a headlight lens for a vehicle headlight, in particular for a motor vehicle headlight, wherein the headlight lens has an, in particular blank-pressed, integral body which is composed of a transparent material and has at least one light entry surface and has at least one optically active light exit surface, characterized in that the integral body comprises a light tunnel which merges with a bend in a light conduction part for forming the bend as a light/dark boundary, wherein the radiation power of the light which enters the headlight lens through the light entry surface and exits from the light exit surface (for forming the bend as a light/dark boundary) is at least 80% of the radiation power of the light which enters the headlight lens through the light entry surface.
