A process, in particular a 3D printing process, for producing a spectacle lens is disclosed. The process includes providing a coated substrate, providing a three-dimensional model of the spectacle lens, digitally cutting the three-dimensional model into individual two-dimensional layers, providing at least one printing ink, typically a 3D printing ink, building up the spectacle lens from the sum of the individual two-dimensional layers with a printing operation on the substrate, and hardening of the spectacle lens. The hardening can take place completely or partially after application of individual volume elements or after application of a layer, and the partial hardening can be completed after conclusion of the printing process. |
