Abstract:
(EN) Provided is a spectacle lens which has a lens base containing a blue light absorbing compound and a multilayer film containing a metal layer with a thickness of 1.0–10.0 nm, and in which the blue light blocking rate is at least 21.0%, the average reflectance measured on the object-side surface in the wavelength region of 400–500 nm is no higher than 1.00%, and the average reflectance measured on the eyeball-side surface in the wavelength region of 400–500 nm is no higher than 1.00%.
(FR) L'invention concerne un verre de lunettes qui a une base de verre contenant un composé absorbant la lumière bleue et un film multicouche contenant une couche métallique d'épaisseur comprise entre 1,0 et 10,0 nm et dans lequel le taux de blocage de lumière bleue est d'au moins 21,0 %, le facteur de réflexion moyen, mesuré sur la surface côté objet dans la région de longueur d'onde de 400 à 500 nm, ne dépasse pas 1,00 % et le facteur de réflexion moyen, mesuré sur la surface côté globe oculaire dans la région de longueur d'onde de 400 à 500 nm, ne dépasse pas 1,00 %.
(JA) 青色光吸収性化合物を含むレンズ基材と膜厚1.0~10.0nmの金属層を含む多層膜とを有し、青色光カット率が21.0%以上であり、物体側表面において測定される400~500nmの波長域における平均反射率が1.00%以下であり、かつ眼球側表面において測定される400~500nmの波長域における平均反射率が1.00%以下である眼鏡レンズが提供される。
