Title (EN) ACTIVE OPTICAL FILTER FOR SPECTACLE LENSES
(FR) FILTRE OPTIQUE ACTIF POUR VERRES DE LUNETTES
Abstract:
(EN) Active optical filter adapted for a spectacle lens, the active optical filter being configured so as to filter light radiations over at least one predetermined range of wavelengths, wherein the full width at half maximum of the filtering function of the optical filter is smaller than or equal to 100 nm.
(FR) La présente invention a trait à un filtre optique actif adapté à un verre de lunettes, le filtre optique actif étant conçu de manière à filtrer les rayonnements lumineux sur au moins une gamme de longueurs d'onde prédéfinie, la largeur totale à mi-hauteur de la fonction de filtrage du filtre optique étant inférieure ou égale à 100 nm.
