Abstract
The present invention concerns a method of manufacturing a lens for motor vehicle lighting modules, the method being intended to generate on the output surface (104) of said lens (100) microstructures formed by level differences situated on said output surface (104), the method including the following steps of forming a meshing on the output surface of said lens such that each mesh has similar dimensions, and generating in each mesh a microstructure formed by an output surface level difference, each level difference having a profile that varies as a function of the position of the mesh on the output surface of the lens.
