Abstract

lente óptica fotocromática com atenuação de luz azul seletiva, ou mais especificamente a presente invenção refere-se a um produto de lente fotocromática para óculos que compreende um material (ou materiais) e agente (ou agentes) filtrante seletivo que atenuam seletivamente uma porção da região espectral da luz azul entre 400 nm e 500 nm. a atenuação seletiva compreende, de preferência, uma redução máxima na transmitância na região filtrada de cerca de 10 a 25% t em relação a pelo menos uma região espectral adjacente quando o produto de lente está no estado de repouso e uma redução máxima na transmitância que é mensuravelmente menor do que a transmitância de pelo menos uma região adjacente do espectro visível quando o produto de lente escurece no estado ativado.
