Abstract

<B>LENTE OFTáLMICA MULTIFOCAL<D>, compreendendo uma região de visão de longe, uma região de visão de perto uma região de visão intermediária, a qual tem uma região de visão de perto elevada e um campo de visão amplo na região de visão de perto, na região de visão intermediária e na região de visão de longe. A progressão é suave, embora a distância entre um centro de montagem na lente e o pnto no qual o aumento de ampliação é 85% maior do que o aumento de ampliação em um ponto de controle da visão de longe seja inferior a 16 mm, enquanto que, simultaneamente, o cilindro máximo dentro de um círculo de 20 mm de raio centralizado em um centro geométrico da lente é mantido a um valor baixo.
