Abstract
(EN) The present invention provides a spectacle lens that has anti-fogging properties and excellent light resistance and that is exhibits little change in color tone. The spectacle lens comprises a base material and a water-absorbing anti-fogging layer which is provided as the outermost layer on the base material. The water-absorbing anti-fogging layer contains an ultraviolet absorber. The water-absorbing anti-fogging layer has spectral characteristics such that light transmittance is less than 5% at least at 350-370 nm but 5% or more at a wavelength of 370 nm or more.
(FR) La présente invention concerne une lentille de lunettes qui présente des propriétés antibuée et une excellente résistance à la lumière et qui présente peu de changement de ton de couleur. La lentille de lunettes comprend un matériau de base et une couche antibuée absorbant l'eau qui est disposée en tant que couche la plus à l'extérieur sur le matériau de base. La couche antibuée absorbant l'eau contient un absorbeur d'ultraviolets. La couche antibuée absorbant l'eau présente des caractéristiques spectrales telles que la transmittance de la lumière est inférieure à 5 % au moins à de 350 à 370 nm mais 5 % ou plus à une longueur d'onde de 370 nm ou plus.
(JA) 防曇性を有し、耐光性に優れ、色味の変化が少ない眼鏡レンズを提供するものであり、基材と、前記基材上に最外層として設けられた吸水性防曇層とを有し、前記吸水性防曇層は紫外線吸収剤を含み、前記吸水性防曇層は、少なくとも350~370nmにおける光透過率が5%未満であり、光透過率が5%以上になる波長が370nm以上である分光特性を有する、眼鏡レンズ。
