Claim:
1. An ophthalmic lens for at least one of slowing, retarding or preventing myopia progression, the ophthalmic lens comprising: a center optic zone including optics to correct a myopic refractive error; a power profile with a first peripheral zone surrounding the center optic zone and having a power that increases from a power in the center optic zone to a first peak power of about +2 diopters above the power in the center optic zone at a radial distance of 1 mm from a geometric center of the center optic zone and then decreases to a first valley power of about +0.75 diopters at a radius of about 1.75 mm from the geometric center of the center optic zone; and a second peripheral zone surrounding the first peripheral zone and having a power that increases from the first valley power to a second peak power of about 1.25 diopters above the power in the center optic zone at a radius of about 2.25 mm and then decreases monotonically to an edge of the optic zone.
