Method for producing an optical element, for example a headlight lens for a motor vehicle headlight

A method for producing an optical lens, the method comprising:

• providing a partial-optic with a convex coating surface made of a first transparent optical material, the first transparent optical material being inorganic glass having a first refractive index;
• providing a mold with a concave cavity;
• providing a liquid transparent second optical material, the transparent second optical material being a hybrid polymer;
• placing liquid transparent second optical material into the concave cavity of the mold;
• pressing the partial-optic with the convexly curved surface into the concave cavity of the mold, such that an optical lens comprised of the partial-optic and an optically effective coating formed on the convexly curved coating surface is formed, the optically effective coating having a second refractive index;
• curing the optically effective coating;
• and
• hardbaking the optically effective coating by heat treatment after curing such that the second refractive index being substantially the same as the first refractive index.
