    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.

    Abstract: A method for manufacturing an optical lens having at least a reference optical power at a given point is described. This method includes the steps of: selecting, among a fixed number of optical elements, one optical element to manufacture the optical lens, the step of selecting being executed as a function of the reference optical power at the given point of the optical lens, the step of selecting being executed such that the selected optical element has an optical power having an absolute value lower than or equal to the absolute value of the reference optical power at the given point of the optical lens; and manufacturing the optical lens using an additive manufacturing technology by depositing a complementary portion on the selected optical element. A manufacturing system for manufacturing an optical lens is also described.
