Abstract
An ophthalmic lens for myopia control. A first surface of the lens varies across the lens to form a first surface power map. A second surface of the lens varies across the lens to form a second surface power map. Each of the first and second surface power maps comprise a spiral. The spirals formed by the first and second surface power maps twist in opposing directions. Related methods are also described.
