A method of manufacturing an ophthalmic lens comprising: an ophthalmic lens data providing step (S1) during which ophthalmic lens data corresponding are provided, a semi-finished lens blank providing step (S2) during which a semi-finished lens blank is provided, a transfer function determining step (S3) during which the transfer function to be applied to the first optical surface of the ophthalmic lens so as to correspond to the first lens blank surface is determined, an one side lens data calculating step (S4) during which one side lens having second surface that corresponds to the second optical surface calculated by applying the transfer function, a machining step (S5) during which the semi-finished lens blank is machined according to the one side lens data, a deforming step (S6) during which the machined semi-finished lens blank is deformed so as to obtain the ophthalmic lens.
