    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 includes acquiring prescription data including an addition value. The method includes generating virtual surface data of a progressive addition lens for a further operation of surfacing of a lens blank, the operation of surfacing being configured to transform the lens blank into a surfaced lens satisfying the prescription data. The generating virtual surface data includes selecting a virtual base surface in a virtual base surface database, the selection being independent of the prescribed addition value, processing the selected virtual base surface according to the prescribed addition value to obtain a modified virtual base surface, selecting a virtual adjusting surface in a virtual adjusting surface database at least on the basis of a value of a parameter relative to the modified virtual base surface, and combining the modified virtual base surface and the selected virtual adjusting surface to form a virtual progressive adjusted surface.

    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.
