Abstract: An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface has a surface profile including a base curvature and a plurality of morphed sinusoidal phase shift structures. The base curvature may correspond to a base optical power of the ophthalmic lens, and the morphed sinusoidal phase shift structures may be configured to extend depth of focus of the ophthalmic lens at intermediate or near viewing distances.
