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 comprising the steps of:
€¢ providing geometrical data of the spectacle frame,
€¢ providing wearer data,
€¢ optimization of the optical system (OS) according to at least the criteria consisting of the geometrical data of the spectacle frame, the wearer data and at least one positioning data, so as to generate at least two optical surfaces (S1, S2).
