Abstract

Una lente oftálmica multifocal en donde una primera superficie de la lente tiene forma para formar un mapa de potencia de superficie y una segunda superficie de la lente tiene forma para formar un segundo mapa de potencia de superficie. El primer mapa de potencia de superficie y el segundo mapa de potencia de superficie juntos forman un mapa de potencia de lente. El primer mapa de potencia de superficie, el segundo mapa de potencia de superficie, o el mapa de potencia de lente comprende una espiral. La espiral tiene una variación a lo largo de al menos una porción de la lente. También se proporcionan métodos para fabricar y usar tales lentes.
