Method Of Calculating An Optical System According To A Given Spectacle Frame

摘要

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.

1. A method of calculating an optical system of an ophthalmic lens according to a given spectacle frame, said ophthalmic lens comprising a back surface and a front surface arranged to deliver an ophthalmic vision image, where the back surface is positioned closest to a wearer's eye when the ophthalmic lens is worn, the ophthalmic lens comprising a light-guide optical element having a proximal surface and a distal surface, said light-guide optical element being arranged to output a supplementary image to the wearer through an exit surface located on the proximal surface, 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; and optimizing the optical system according to at least the morpho-geometrical parameter data as a target.
