The present disclosure provides a suitable method for producing a headlight lens for a vehicle headlight, for example for a motor-vehicle headlight, wherein the headlight lens comprises an integral body made of glass, wherein the integral body comprises at least one light tunnel and one light-passage section having at least one optically active light exit surface, wherein the light tunnel comprises at least one light entry surface and, with a bend, transitions into the light-passage section in order to image the bend as a bright-dark-boundary by means of light directed into the light entry surface.

A method for manufacturing an optical element, the method including: heating an optical element material by suspending it in a gas; supplying the heated optical element material from a direction which intersects a central axis interconnecting centers of a first mold and a second mold to a space between molds in a non-contact state, the space between molds being a space between the first mold and the second mold; pressurizing the optical element material supplied to the space between molds by the first mold and the second mold; and cooling the pressurized optical element material.
