Beschreibung
Zusammenfassung:	A method, implemented by computer means for comparing a first ophthalmic lens with a second ophthalmic lens, the method comprising: - a first optical function providing step, during which a first optical function of a first ophthalmic lens LI is provided, the first optical function comprising at least a first set of values of an optical parameter Gj, the values of the first set of values corresponding to the values of said optical parameter of the first ophthalmic lens in a set of gaze directions, - a second optical function providing step, during which a second optical function of a second ophthalmic lens L2 is provided, the second optical function comprising at least a second set of values of the optical parameter Gj, the values of the second set of values corresponding to the values of said optical parameter of the second ophthalmic lens in the set of gaze directions, - a subsets determining step, during which at least a first and a second subset of gaze directions are selected within the set of gaze direc
