Abstract

LENTE MULTIFOCAL OFTÁLMICA, E, MÉTODO PARA FABRICAR UMA LENTE MULTIFOCAL OFTÁLMICA . Uma nova geração de lentes multifocais oftálmicas e um método para fabricar as mesmas. As lentes proveem pelo menos pontos focais para visão próxima, intermediária e distante. O corpo da lente provê um ponto focal refrativo para visão intermediária. O corpo da lente compreende uma rede de difração (91) que opera como um divisor de onda óptico que provê um ponto focal difrativo para visão próxima e um ponto focal de difração para visão distante. O corpo da lente compreende uma zona central monofocal (92) que se estende por uma distância do eixo geométrico óptico do corpo da lente e provê um ponto focal que coincide com um dos pontos focais difrativos. A rede de difração (91) é disposta a partir de um ponto de transição (93) em uma posição radial do corpo da lente em que termina a zona central monofocal (92). No ponto de transição (93), a rede de difração (91) e a zona central monofocal (92) têm valores de amplitude coincidentes.
