Abstract
(EN) A simultaneous multifocal contact lens (10) for correcting vision acuity of an individual is disclosed. The contact lens comprises a central region (25) radially surrounded by at least one far vision focal region (30) and at least one near vision focal region (26), wherein a near vision additional correction of the at least one near vision focal region (26) is ovecorrected by at least 10 % with respect to the near vision additional correction prescribed for the individual according to the standard prescription for lens radius design.
(FR) L'invention concerne une lentille (10) de contact à foyers progressifs simultanés servant à corriger l'acuité visuelle d'un sujet. La lentille de contact comporte une zone centrale (25) radialement entourée d'au moins une zone focale (30) de vision lointaine, et d'au moins une zone focale (26) de vision proche ; une correction supplémentaire en vision proche de la ou des zones focales (26) de vision proche est surcorrigée d'au moins 10 % par rapport à la correction supplémentaire en vision proche prescrite pour le sujet, conformément à la prescription standard en matière de conception de rayon de lentille.
