Zusammenfassung:The invention provides a method for increasing the magnification of a lens without changing the dioptric power. The method of the invention uses a measurement or an estimate of an individual's retinal function in designing the lens to provide the magnification needed by the individual without increasing the dioptric power of the individual's lens. L'invention porte sur un procédé visant à augmenter le grossissement d'un verre sans modifier la puissance dioptrique. Le procédé de l'invention utilise une mesure ou une estimation de la fonction rétinienne d'un individu dans la conception du verre afin d'obtenir le grossissement dont l'individu a besoin sans augmenter la puissance dioptrique du cristallin de l'individu.
