    Abstract: A method for determining target optical functions for a pair of ophthalmic lenses is provided, the method comprising steps of: - generating a first target optical function (OFT1) for a first lens of the pair based at least on data relating to a first eye, - generating a second target optical function (OFT2) for a second lens of the pair based at least on data relating to the first eye. This method makes it possible to obtain optical functions having improved symmetry. Thus, when using the target optical functions in an optical optimization method, lenses with improved binocular properties can be obtained. The comfort of the wearer of the pair of lenses is thus improved.

    Abstract: L'invention se rapporte à un procédé de détermination d'une lentille ophtalmique pour un il d'un porteur, le procédé comportant les étapes de : - mesure, sur le porteur en vision binoculaire, des coordonnées tridimensionnelles du centre de rotation de l'il du porteur; - mesure (10) d'au moins une direction de regard en posture naturelle - détermination de la position souhaitée de la lentille ophtalmique; - calcul des caractéristiques de la lentille ophtalmique en utilisant les coordonnées mesurées et la position déterminée et la direction mesurée en posture naturelle. La mesure de la position du centre de rotation de l'il en vision binoculaire assure que la lentille obtenue est mieux adaptée au porteur.

    Abstract: Une lentille ophtalmique progressive est proposée, qui est adaptée pour la pratique d'une activité sportive. Pour cela, la lentille présente une zone de vision de loin qui est élargie, ainsi qu'un champ de vision périphérique qui est dégagé et dont les gradients de sphère moyenne sont faibles. Lors de l'attribution d'une telle lentille progressive à un porteur, la lentille peut présenter une valeur d'addition qui est sensiblement égale à une valeur prescrite, ou bien une valeur d'addition qui est réduite par rapport à la valeur prescrite.

    Abstract: The invention relates to a method for determining a progressive ophthalmic lens, comprising: - determining a first intermediate value of regression (d1) as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the rear surface of the lens less or equal to a first predetermined value (V1); - determining a second intermediate value of regression (d2) as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the front surface of the lens superior or equal to a second predetermined value (V2); - determining a third intermediate value of regression (d3) as the strongest regression that can be applied on the front surface of the lens while keeping an addition on the rear surface of the lens less or equal to a third predetermined value (V3); - determining a value of regression (d) for the front surface as the maximum value among the first, second and third intermediate values of regression.

    Abstract: The invention provides a progressive ophthalmic lens suitable to be worn by a person engaged in a sporting activity. For this purpose the lens has a far vision region which is enlarged, and a peripheral field of vision which is separated and whose mean sphere gradients are gentle. When a progressive lens of this kind is allocated to a wearer, the lens can have an addition value that is approximately equal to a prescribed value, or an addition value that is less than the prescribed value.

    Abstract: The invention relates to a method for determining a progressive ophthalmic lens wherein: - a first or a second reference axes (G1, G2) are determined, the first reference axis being set to a value comprised between [?T - 20°, ?T + 20°] with ?-T being the average axis of astigmatism over a first temporal portion (Portion1), and the second reference axis being set to a value comprised between [?N - 20°, ?N + 20°] with ?N being the average axis of astigmatism over a second nasal portion (Portion2); - over the first portion, the sphere value along the first reference axis is superior to the sphere value along a perpendicular axis to the first reference axis (Formula I); or - over the second portion, the sphere value along the second reference axis is superior to the sphere value along a perpendicular axis to the second reference axis (Formula II). The method enables an improved distortion without degrading the performance in term of correction of the optical power defect and optical residual astigmatism. This results in an increased comfort for the wearer. The invention further relates to a progressive ophthalmic lens, a method for manufacturing a pair of progressive ophthalmic lens, a set of apparatuses for manufacturing a pair of ophthalmic lenses, a set of data, a computer program product and a computer readable medium associated to this method.
