Abstract

La présente invention concerne un dispositif pouvant être porté (1), comprenant un élément optique (2) et une partie pouvant être portée (3). L'élément optique (2) est situé dans un site du champ de vision d'un utilisateur et comprend un filtre passe-bande qui, à partir de la lumière ambiante incidente, transmet la lumière d'une région de longueur d'onde spécifique, qui induit le sommeil. Le filtre passe-bande a une région de longueur d'onde maximale comprise entre 430 et 550 nm, et transmet une lumière à bande très étroite qui présente une largeur à mi-hauteur inférieure ou égale à 10 nm. De plus, le filtre passe-bande présente une configuration dans laquelle une multicouche diélectrique et un filtre coloré sont empilés ensemble. Le filtre coloré coupe la lumière transmise de la multicouche diélectrique qui est passée à une longueur d'onde plus courte en fonction de l'angle incident de la lumière.
