Abstract: Disclosed is a method for determining an optical function of a progressive ophthalmic lens for a wearer, including: providing a prescription of the wearer; providing wearing data including at least a numerical parameter; providing by at least one processor a set of predefined optical functions including at least a first predefined optical function adapted to the prescription of the wearer and to a first predefined wearing parameter and a second predefined optical function for the prescription of the wearer and to at least a second predefined wearing data parameter, the second predefined optical function being different from the first; and determining an optical function of the progressive ophthalmic lens, so: when the wearing data parameter?a threshold value, the optical function of the lens=first predefined optical function, and when the wearing data parameter<the threshold value, the optical function=the second predefined optical function.

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.

Abstract: A method for determining an optimal eyeglass lenses design for a viewer (1) comprising the successive steps of: showing the viewer (1) a stereoscopic scene including optical effects of a first lens design;—introducing a relative movement between the viewer (1) and the shown stereoscopic scene, said scene being shown with optical effects of the first lens design; expressing the viewer's opinion; showing the viewer (1) a stereoscopic scene including optical effects of a modified lens design; introducing a relative movement between the viewer (1) and the shown stereoscopic scene, said scene being shown with the modified lens optical effects; expressing again the viewer's opinion; repeating the three last steps up to viewer's satisfaction. A system for customizing vision correction suitable to implement said method. Related computer program for dynamically calculating a stereoscopic image.
