Abstract

En un aspecto de la invención, se describe un lente oftálmico trifocal que incluye una óptica teniendo por lo menos una superficie óptica, y una pluralidad de zonas difractivas dispuestas sobre una porción de la superficie alrededor de un eje óptico de la óptica. Por lo menos dos de las zonas difractivas tienen diferentes áreas de manera que ocasionan el ampliamiento de perfiles de energía óptica en un foco cercano y uno lejano de las zonas difractivas para generar un foco intermedio.
