ABSTRACT:
The plano-convex lens of a projection headlight has a holding edge (4) integrally formed on an outer lens edge and a supporting edge (5) projecting from its plane surface (3) and formed integrally with the holding edge (4). The supporting edge (5) and the holding edge (4) form a continuous cylindrical outer circumferential surface (45) extending over their outer sides. The convex surface (2) and the plane surface (3) of the lens are bright pressed surfaces so that the grinding and polishing steps usually used in making the lens can be eliminated. The method of manufacturing the lens including bright pressing the convex and plane surfaces is also part of the invention.
