Abstract

Patente de Invenção: <B>"LENTES PARA BLOQUEIO DE UV E MATERIAL CONTENDO BENZOTRIAZóIS E BENZOFENONAS"<D>. São descritas lentes de contato ou lentes intra-oculares com bloqueio de ultravioleta melhorado (UV) para satisfazer as especificações ANSI Classe 1, que incluem quantidades eficazes melhoradas de dois compostos absorvedores diferentes de UV. Um absorvedor de UV é derivado de benzotriazol e ou outro absorvedor de UV é um derivado de benzofenona. As lentes podem ser feitas de um polímero hidrogel formado por polimerização de um ou mais monómeros apropriados para fabricação de tais lentes.
