Abstract:
A method for manufacturing an ophthalmic lens (12), includes a marking step for producing permanent technical marks (24) on the lens, which includes a body (29), a first surface (20) and a second surface (28) opposite the first surface (20); the step of additive manufacturing (110-112) of the body and the first and second surfaces, by depositing a plurality of first predetermined volume elements of a first material having a first complex index of refraction (35), in order to obtain first and second optical surfaces, respectively, of the first and second surfaces; and the step of additive manufacturing (113) of the marks by depositing, during the deposition of a plurality of the first volume elements of the first material, at least one second predetermined volume element of a second material having a second complex index of refraction (30) other than the first complex index of refraction of the first material.
