Abstract

Las realizaciones de la presente se relacionan con una lente multifocal que consta de una region de potencia mayormente esférica y una region de potencia optica progresiva. Las realizaciones de la presente dan lugar a la alineacion y posicionamiento de cada una de estas regiones, a la cantidad de potencia optica producida por cada una de estas regiones, al diseno optico de la region de potencia optica progresiva y a la forma y tamano correctos de cada una de estas regiones. La combinacion de estos parámetros de diseno da origen a un diseno optico con menos astigmatismo desfavorable y distorsion, así como un mayor ancho de canal y una menor longitud del canal en comparacion con las PAL convencionales. Las realizaciones de la presente también pueden dar origen a una nueva zona de distancia lejana-intermedia de la solicitud y también pueden conferir mayor estabilidad vertical de vision dentro de una zona de la lente.
