    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: 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: 1. A method for calculating a system (S) by optimization, the method comprising the steps of : i. providing a set of system parameters (SP) so as to define a starting system (SS), each system parameter (SP) being set up at a starting value; ii. defining a plurality of criteria (C k); iii. associating for each criterion (C k) a cost function (CF k); iv. defining a plurality of global cost functions (GCF1,..., GCF ND) by associating to each global cost function (GCF p) at least one cost function (CF k); v. defining a vector of variable parameters (X p) associated to each global cost function (GCF p) by selecting for each vector of variable parameters (X p) at least one system parameter (SP); vi. optimizing the plurality of global cost functions (GCF1,..., GCF ND) by modifying the values of the system parameters of the vectors of variable parameters (X1,..., X ND) so as to obtain an intermediate system (IS); vii) repeating step vi) until an equilibrium is reached so as to obtain a system (S).

    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.
