<p>The method involves forming a meshing having meshes (106) whose patterns form tiles or concentric rings, on an output surface of a lens such that each mesh has similar dimensions. Microstructures formed by an output surface level difference (108) are generated in the mesh such that the level difference presents an symmetry axis, where the level difference includes a profile that varies as a function of position of the mesh on the output surface of the lens, and the symmetry axis corresponds to an revolution axis or to an rotation axis. An independent claim is also included for a lens for a lighting module of a car.</p> |
