Abstract
A method for manufacturing an ophthalmic lens () having at least one optical function, includes the step of additively manufacturing () a complementary optical element () by depositing a plurality of predetermined volume elements () of a material having a predetermined refraction index on a predetermined manufacturing substrate (), the complementary optical element being configured such as to be assembled with an initial optical system (), the manufacturing step including the step of determining a manufacturing setting () from properties relating to the deformation of the complementary optical element, which deformation is caused by transferring the latter onto the initial optical system, and the step of determining a setting including the step of determining the deformation properties () of the complementary optical element from geometric properties of the manufacturing substrate and the initial optical system and from properties of the optical function to be provided to the ophthalmic lens.
