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.
Claims7
An ophthalmic lens, comprising:
- an anterior surface, a posterior surface, and an optical axis, at least one of the anterior surface and the posterior surface having a surface profile comprising a morphed sinusoidal phase shift structure;
- wherein the morphed sinusoidal phase shift structure is in the form of an asymmetric sinusoidal wave and comprises a plurality of zones, each zone comprising a single sinusoidal period.
