Abstract: A method of manufacturing an ophthalmic lens having at least one optical function includes: a step of additively manufacturing a complementary optical element by depositing a plurality of predetermined volume elements on a predetermined build support, the complementary optical element being configured to provide at least a part of the optical function of the ophthalmic lens, wherein the build support includes at least one added value or adhesive configured to provide to the ophthalmic lens at least one added function. An ophthalmic lens including a build support and a complementary optical element as well as an ophthalmic lens obtained by such a manufacturing method.

Abstract: A method of determining at least one parameter of an ophthalmic lens (40) including a complementary optical element (12) obtained by additive manufacturing and configured to provide at least a part of the optical function of the ophthalmic lens, the determining method including a step of providing two characterizing surfaces simulating two opposite surfaces of a complementary optical element (12), the distance between the two characterizing surfaces along a thickness axis (Z) defining the thickness of the complementary optical element; a step of optimizing the distance between the two characterizing surfaces (20) along the thickness axis (Z) so that the thickness of the complementary optical element reaches a thickness threshold while complying with the optical function of the ophthalmic lens (40); and a step of determining at least one parameter of the ophthalmic lens (40) on the basis of the optimized distance.

Abstract: A method of manufacturing an ophthalmic lens, including: a step of providing a starting optical system (30) having a first optical function and a first main refractive index; a step of providing a transition layer (20) intended to be disposed between the starting optical system (30) and a complementary optical element (12) having a second main refractive index, the transition layer (20) aiming at reducing unwanted reflection caused by the mismatch between the first and the second main refractive index, the transition layer (20) having a transition optical function; and a step of additively manufacturing the complementary optical element (12) on the transition layer (20), the complementary optical element (12) having a second optical function, the second optical function being predetermined as a function of the first optical function and of the transition optical function.
