Abstract
An ophthalmic lens having a central zone and a peripheral zone. The central zone having a first region characterized by a substantially constant first optical power and a second region disposed radially outward of the first region having periodic positive and negative deviations in power as a function of radial position, relative to the substantially constant first power. The peripheral zone disposed radially outward of the central zone. The peripheral zone having periodic positive and negative deviations relative to an average optical power, the average optical power increasing as a function of radius from the first power.

An ophthalmic lens, comprising:
- a central zone having a first region characterized by a substantially constant first optical power and a second region disposed radially outward of the first region having positive and negative deviations in power as a function of radial position, relative to the substantially constant first power;
- and
- a peripheral zone disposed radially outward of the central zone, the peripheral zone having positive and negative deviations as a function of radial position, relative to an average optical power, the average optical power increasing as a function of radius from the substantially constant first optical power.
