Abstract

En un aspecto, la presente invencion provee un alente oftálmica difractiva (por ejemplo, una LIO difractiva) que comprende un optico que tiene una superficie anterior y una superficie posterior, donde el optico proporciona un foco lejano. Una estructura difractiva frustrada que comprende una pluralidad de zonas difractivas se dispone sobre por lo menos una de estas superficies, de manera de proporcionar un foco cercano. Cada zona está separada de una zona adyacente por una limitacion de zona que imparte una demora optica a la luz incidente. Además, por lo menos dos limitaciones de zona consecutivas están configuradas de modo que una diferencia entre sus demoras de fase asociadas para al menos una longitud de onda de la luz incidente sea mayor que aproximadamente 1/4 longitud de onda, a fin de dirigir una porcion de la luz incidente a una ubicacion entre los focos cercano y lejano.
