Abstract
A method of providing refractive microstructures on a surface of a spectacle lens body by an additive manufacturing process is provided, in which the refractive microstructures are formed by applying and curing a curable material. The process includes forming a layer of a first liquid or viscous curable material and an additional amount of the first curable material or an amount of a second liquid or viscous curable material at locations at which the refractive microstructures shall be formed before curing or pinning the at least one first curable material. Protrusions formed by the additional first curable material or the second curable material are levelled out by material transport processes within the liquid or viscous material in the layer of the at least one curable material. In addition, a spectacle lens with refractive microstructures is provided.
