Abstract

"LENTE DE óCULOS MULTIFOCAL ELETROATIVO". São revelados óculos multifocais eletroativos. Os óculos têm uma pilha de pelo menos duas regiões eletroativas (5560), (5565) e (5570). As regiões eletroativas produzem várias zonas de correção de visão. Os óculos também têm um controlador para ativar de forma independente as regiões eletroativas para a produção de zonas de correção da visão. Também é revelado um óculos multifocal eletroativo que tem uma zona combinada. A zona combinada fornece uma transição de poder óptico entre zonas de correção de visão.
