Abstract

"LENTE OFTáLMICA MULTIFOCAL PROGRESSIVA COM VARIAçãO RáPIDA DE POTêNCIA". Que tem uma região para visão distante, uma região para visão intermediária e uma região para visão próxima, um meridiano principal da progressão que passa através das ditas três regiões, e uma adição de potência igual a uma diferença na esfera média entre um ponto de controle da região para visão próxima e um ponto de controle da região para visão distante. A lente tem um comprimento da progressão menor do que 12 mm, definido como a distância vertical entre um centro de montagem e um ponto no meridiano onde a esfera média é maior do que a esfera média no ponto de controle para visão distante em 85% do valor da adição de potência. Para assegurar o desempenho óptico excelente da lente apesar desse comprimento curto da progressão, a razão entre o produto do cilindro vezes a norma do gradiente da esfera, e o quadrado da adição de potência é menor do que 0,08 mm^ -1^ em cada ponto dentro de um disco de 40 mm de diâmetro centrado no centro da lente. Adicionalmente, o cilindro dentro dessa parte do disco situada acima do centro de montagem é menor do que 0,5 vez a adição de potência.
