Abstract
A method for manufacturing an ophthalmic lens using an additive manufacturing technology, based on an optical element and initial manufacturing data, the initial manufacturing data including data defining a complementary portion to deposit on the optical element to form the ophthalmic lens from the optical element, includes the steps of: positioning the optical element on a support; determining a positioning error between the position of the optical element and a reference position on the support using a measurement directed to the optical element; determining a deterioration on the optical element; calculating updated manufacturing data taking into account initial manufacturing data and the determined positioning error; and manufacturing the ophthalmic lens using the updated manufacturing data by the additive manufacturing technology by depositing the complementary portion on the optical element to form the ophthalmic lens from the optical element. A manufacturing system for manufacturing an ophthalmic lens is also described.
