Abstract

The invention relates to a method for manufacturing an ophthalmic lens (12) , comprising a marking step for producing permanent technical marks (24) on said lens , which comprises a body (29), a first surface (20) and a second surface (28) opposite said first surface (20); the step of additive manufacturing (110 -112) of said body and said 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 said marks by depositing , during said deposition of a plurality of said first volume elements of said first material , at least one second predetermined volume element of a second material having a second complex index of refraction (30) other than said first complex index of refraction of said first material.
