Abstract
LENTE DIFRATIVA MULTIFOCAL. A presente invenção provê uma lente de difração multifocal capaz de eficientemente usar luz. Uma lente de difração multifocal 100 tem uma grade de difração 1c. A luz de ordem negativa L2 gera um ponto focal f2 para a visão distante, a luz de ordem zero L1 gera um ponto focal f1 que está mais próximo do que aquele para a visão distante, o número de pontos focais é dois ou mais e uma posição focal fc para a visão distante na avaliação de desempenho multicolorido está disposta mais próxima do que uma posição focal fs para a visão distante na avaliação de desempenho de cor única.
