CA 2708516

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.

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.
