Abstract

a presente invenção se refere a uma lente oftálmica com uma reflexão baixa no domínio ultravioleta, compreendendo um substrato transparente com uma face principal anterior e com uma face principal posterior, em que a referida face principal posterior está revestida com um revestimento antirreflexo multicamada compreendendo um empilhamento de pelo menos uma camada apresentando um índice de refração superior a 1,6 e de pelo menos uma camada apresentando um índice de refração inferior a 1,55, em que: o fator de reflexão médio ruv na referida face posterior entre 280 nm e 380 nm, ponderado pela função w (¿), é inferior ou igual a 5%, preferencialmente inferior ou igual a 4%, para um ângulo de incidência de 35°, o croma c* de luz refletida é igual ou inferior a 4, preferencialmente inferior ou igual a 3, para um ângulo de incidência (¿) de 15°.
