Abstract
A method implemented by computer means for calculating a lens optical system of a spectacle ophthalmic lens for a wearer. The method includes providing an aberration target lens fulfilling the requirements of: a first set of aberration data of the aberration target lens, a first set of wearing parameters of the aberration target lens, and a first set of lens parameters of the aberration target lens. The method further includes providing a distortion target 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, and calculating the lens optical system by using an optimization method which jointly uses the aberration target lens and the target distortion values.
