Title (EN) DECENTERED BIFOCAL CONTACT LENSES
(FR) LENTILLES DE CONTACT BIFOCALES EXCENTREES
Abstract:
(EN) Multifocal contact lenses are disclosed having a circular first zone (3) intended for near or distance vision and an annular second zone (4) surrounding the first zone and intended for the other of near or distance vision. The optical axis B-B of the lens is displaced with respect to the geometric axis A-A so that in use the lens is decentered nasally.
(FR) L'invention concerne des lentilles de contact multifocales présentant une première zone circulaire (3), correspondant à une vision rapprochée ou à distance, et une seconde zone annulaire (4), entourant la première, et correspondant à la vision rapprochée ou à distance complémentaire. L'axe optique B-B de la lentille est décalé par rapport à l'axe géométrique A-A de telle manière qu'en cours d'utilisation, la lentille soit excentrée par rapport au nez.
