A contact lens having one or more optimized optical zones that accommodate the specific optical variations of the eye of the wearer such that the optical zone s is placed within the contact lens in relation to the true line of sight of the wearer. To make the contact lens, the variation in the eye of a potential contact lens wearer is measured to determine the true line of sight of the eye, and the location of one or more optical zones in the contact lens are determined such that the optical zone is placed substantially on the true line of sight when fitted in the eye of the wearer, and then the contact lens is manufactured to contain the one or more optimized optical zones.

L'invention concerne une lentille de contact ayant une ou plusieurs zones optiques optimisées s'accommodant aux variations optiques spécifiques de l'oeil du porteur telles que la zone optique soit placée dans la lentille de contact par rapport à la ligne de la vue vraie du porteur. Afin de fabriquer la lentille de contact, on mesure la variation de l'oeil d'un porteur potentiel de lentille de contact afin de déterminer la ligne de la vue vraie de l'oeil, et la localisation d'une ou plusieurs zones optiques dans la lentille de contact sont déterminées de façon que la zone optique soit placée sensiblement sur la ligne de vue vraie une fois ajustée dans l'oeil du porteur. Alors la lentille de contact est fabriquée afin de contenir cette ou ces zones optiques optimisées.
