Abstract
A method of producing an optical device from a volume of a curable composition, includes the following steps: —polymerizing a first portion of the volume by irradiating an external surface of the volume with a light irradiation, thereby increasing a transmittance of the first portion for the light irradiation; —polymerizing a second portion of the volume by irradiating the second portion with the light irradiation through the external surface and the polymerized first portion, wherein the light irradiation has a light intensity varying over the external surface between a first light intensity and a second light intensity distinct from the second light intensity. A corresponding system is also described.
