Abstract: A method for manufacturing an ophthalmic lens (12), includes a marking step for producing permanent technical marks (24) on the lens, which includes a body (29), a first surface (20) and a second surface (28) opposite the first surface (20); the step of additive manufacturing (110-112) of the body and the first and second surfaces, by depositing a plurality of first predetermined volume elements of a first material having a first complex index of refraction (35), in order to obtain first and second optical surfaces, respectively, of the first and second surfaces; and the step of additive manufacturing (113) of the marks by depositing, during the deposition of a plurality of the first volume elements of the first material, at least one second predetermined volume element of a second material having a second complex index of refraction (30) other than the first complex index of refraction of the first material.

Abstract: A method for selecting base-curves for an ophthalmic lens according to given prescription data comprising the steps of : - providing a base-curve series consisting of a plurality of base-curves; - calculating a target lens according to the prescription data; - calculating the base-curves calculated lenses according to the prescription data; - selecting, for at least an optical parameter and/or a geometrical parameter, a threshold value for the difference between the base-curves calculated lenses values and the target lens value of said parameter (s}; -- determining the list of the base-curves of the base-curve series where said difference for said parameter (s) is less or equal to the selected threshold value (s).
