Abstract

La présente invention a trait à une lentille de contact à phases multiples (100). La lentille de contact à phases multiples comporte de multiples zones (Z) à puissance de réfraction. Une ou plusieurs parmi les zones présente(nt) une phase additionnelle correspondante (P) basée sur des principes de codage d'images qui améliore la profondeur de champ comparée à la lentille de contact sans phase additionnelle. Les composants des phases multiples assurent des degrés de liberté supplémentaires pour l'équilibrage et l'optimisation de la lentille en fonction de la préférence d'un utilisateur donné.
