Abstract

"LENTES PARA óCULOS MULTIFOCAIS DE QUATRO ZONAS E PROCESSO PARA PROJETAR UMA LENTE MULTIFOCAL". A presente invenção proporciona lentes multifocais contendo pelo menos quatro zonas de diferentes poderes de refração. As zonas são posicionadas de modo que o usuário é capaz de usar a parte mais inferior da lente para ver mais claramente objetos a distâncias superiores a 45 cm do olho, em comparação com as lentes multifocais convencionais.
