A METHOD IMPLEMENTED BY COMPUTER MEANS FOR CALCULATING A LENS OPTICAL SYSTEM OF A SPECTACLE OPHTHALMIC LENS FOR A WEARER

摘要

A method implemented by computer means for calculating a lens optical system (OS) of a spectacle ophthalmic lens for a wearer, wherein the method comprises the steps of: providing an aberration target lens (ATL) fulfilling the requirements of: ⋅ a first set of aberration data of the aberration target lens (ATL), ⋅ a first set of wearing parameters of the aberration target lens (ATL), and ⋅ a first set of lens parameters of the aberration target lens (ATL); providing a distortion target (DT) consisting of target distortion values where the target distortion values are reduced or enhanced in at least a modified distortions zone when compared to the distortion values of the aberration target lens (ATL); calculating the lens optical system (OS) by using an optimization method which jointly uses the aberration target lens and the target distortion values.
