Abstract

La présente invention concerne une lentille filtre protectrice à usage ophtalmique et un procédé de production d'une telle lentille. Cette lentille présente des valeurs de composantes trichromatiques Z et Y entre 0,25-0,40, une longueur d'onde dominante entre 570-580 nm sur un diagramme de mélange de couleurs, une baisse de transmission nette entre 450-500 nm, et une transmission ne dépassant pas 30 % entre 400-450 nm.
