Abstract
A method of calculating an optical system (OS) of an ophthalmic lens according to a given spectacle frame, said ophthalmic lens comprising a back surface (BS) and a front surface (FS) arranged to deliver an ophthalmic vision image (VI), a light-guide optical element having a proximal surface (PS) and a distal surface (DS), said light-guide optical element being arranged to output a supplementary image (SI), wherein the method comprises the steps of: providing at least a morpho-geometrical parameter data of the frame or of the light-guide optical element; optimizing the optical system (OS) according to at least the morpho-geometrical parameter data as a target.
