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.
