    摘要： The invention relates to a headlight (1) for vehicles, comprising at least one primary optical element (2) having at least one light exit surface (6), at least one secondary lens (3) associated with the at least one primary optical element for imaging the at least one light exit surface as a light image onto the road, wherein the at least one secondary lens has a preferably aspherical front light exit surface (15), a rear of light entry surface (14), and substantially planar boundary surfaces (10, 11, 12, 13) between the front light exit surface and the rear light entry surface. In said headlight a rounded edge (27, 30), the surface of which is G2-constant, is provided in the junction region of an upper and/or lower boundary surface (10, 11) and the front light exit surface (15), wherein the average radius of curvature (r1, r2) is in a range from 2 to 30 % of the radius of curvature (R) of the light exit surface (15) of the at least one secondary lens. The rounded edge (27, 30) in the junction region of the upper and/or lower boundary surface (10, 11) and the front light exit surface (15) is preferably at least G1-constant or G2-constant.
