The invention locally deforms a flat surface of a substrate made of glass or a glass ceramic by applying heat exclusively within a locally limited region via the flat surface by laser radiation, a gas flame, infrared radiation, microwaves or a plasma discharge directed towards the flat surface of the substrate to soften the substrate at least on the flat surface within the locally limited region; applies a force acting on the softened flat surface within the locally limited region which deforms the softened surface of the substrate within the locally limited region; cools the substrate to obtain a set deformed surface within the locally limited region; and applies heat exclusively within the locally limited region via the flat surface of the substrate to produce a temperature and viscosity gradient inside the substrate laterally and orthogonal to the flat surface within the locally limited region.
