Abstract:
(EN) Provided is a spectacle lens having a lens substrate containing a blue light absorbent compound, and a multi-layer film containing a metal layer having a thickness of 1.0 to 10.0 nm. The blue light cut ratio is at least 35.0%, the average reflectance in the 400-500 nm wavelength band on the object-side surface as determined by measurement from the object side falls within the range of 15.00 to 25.00%. The average reflectance in the 400 to 500 nm wavelength band on the eye-side surface as determined by measurement from the object side is less than 2.00%.
(FR) L'invention concerne un verre de lunettes ayant un substrat de verre contenant un composé absorbant la lumière bleue, et un film multicouche contenant une couche métallique ayant une épaisseur de 1,0 à 10,0 nm. Le rapport de coupure de lumière bleue est d'au moins 35,0 %, la réflectance moyenne dans la bande de longueurs d'onde de 400 à 500 nm sur la surface côté objet obtenue par mesure à partir du côté objet se situe dans la plage de 15,00 à 25,00 %. La réflectance moyenne dans la bande de longueurs d'onde de 400 à 500 nm sur la surface côté œil obtenue par mesure à partir du côté objet est inférieure à 2,00 %.
(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35.0%以上であり、物体側から測定して求められる物体側表面における400~500nmの波長域での平均反射率が15.00~25.00%の範囲であり、かつ物体側から測定して求められる眼球側表面における400~500nmの波長域での平均反射率が2.00%未満である眼鏡レンズが提供される。
