    Patent number: 10451894
    Abstract: Disclosed is a method for comparing first and second ophthalmic lenses, including: a first optical function providing step, during which a first optical function of a first ophthalmic lens LI is provided, the first optical function including 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 the optical parameter of the first ophthalmic lens in a set of gaze directions, a similar second optical function providing step directed to a second ophthalmic lens L2, a subsets determining step, during which at least a first and a second subset of gaze directions are selected, a comparison step for each subset of gaze directions, an assignment step, during which a subset status is assigned to each subset of gaze directions, the subset status being selected among at least three levels.
