Abstract: A method for determining an ophthalmic lens includes choosing an initial lens with a first face and a second face and defining an initial surface for the second face of the lens with a central zone of diameter Dini and a peripheral zone of inner diameter Drac greater than the diameter Dini of the central zone, each point of the central zone and the peripheral zone having an altitude defined with respect to an axis (Z) normal to the second face of the lens and having the centre of the central zone as its origin, the altitude of the peripheral zone being defined as the minimum of the points situated on the diameter Drac; the peripheral zone having a maximum radius of curvature comprised between the maximum radius of curvature of the first face and the maximum radius of curvature of the central zone.

Abstract: A method for the determination of a progressive ophthalmic lens for a given wearer comprises the stages of: - determining the axial length (LA) of the wearer's eye, - determining an ergorama associating a sight point with each direction of viewing under wearing conditions. - determining power and resulting astigmatism defect targets for each direction of viewing under wearing conditions, the targets being a function of the axial length of the wearer's eye. - calculating the power required on the lens for each direction of viewing by successive iterations in order to obtain the target power defect and the target resulting astigmatism.

Abstract: A method for the determination by optical optimization of a personalized progressive ophthalmic lens intended to be inserted into a frame chosen by a given wearer for whom a power addition has been prescribed in near vision, the method comprising the stages of: - determining at least one parameter representing the frame chosen by the wearer; - measuring parameters representing the wearer's head-eye behaviour; - weighting the parameters representing the wearer's head-eye behaviour with the parameter representing the frame chosen by the wearer; - determining power and resulting astigmatism defect targets for each direction of viewing under wearing conditions, the targets being associated with an individual merit function taking into account the weighted head-eye coordination parameters. The method allows the design of the lens to be adapted to the size and the shape of the frame chosen.

Abstract: A method for the determination by optical optimization of a personalized progressive ophthalmic lens intended to be inserted into a frame chosen by a given wearer for whom a power addition has been prescribed in near vision, the method comprising the stages of: - measuring parameters representing the frame chosen by the wearer; - choosing an initial distribution of power and resulting astigmatism defect targets for each direction of viewing under wearing conditions in an ordinary frame; - calculating transformation coefficients using the measured parameters representing the chosen frame and standard parameters; - calculating a personalized distribution of the power and resulting astigmatism defect targets on the lens by applying the calculated transformation coefficients to the initial distribution. The method makes it possible to retain the proportion of the distribution between the far-vision, near-vision and intermediate-vision zones whatever the size and the shape of the frame chosen.

Abstract: L'invention a pour objet un procédé de détermination par optimisation d'une lentille ophtalmique comprenant les étapes de:- définition d'une surface de départ pour une face de la lentille avec une zone centrale (15) de diamètre Dini et une zone périphérique (17) de diamètre intérieur Drac ;- choix d'une formule d'interpolation ;- optimisation de la lentille en appliquant la fonction d'interpolation aux zones centrale (15) et périphérique (17) pour définir une surface interpolée comprenant une zone de raccord (16), la surface interpolée minimisant une fonction de mérite (FM) pour différentes altitudes relatives de la zone périphérique (17) par rapport à la zone centrale (15).L'invention permet de réduire l'épaisseur de la lentille sans accentuer les défauts d'oblicité pour un bon confort visuel du porteur.
