Abstract

A multi-phase contact lens (100) is disclosed. The multi-phase contact lens has multiple zones (Z) with refractive power. One or more of the zones has/have a corresponding added phase (P) based on image-coding principles that improves the depth of field (DOF) as compared to the contact lens without the added phase. The multiple phase components provide additional degrees of freedom to balance and optimize the lens for a given user’s preference.
