Abstract
A method to provide EDoF ophthalmic lens designs based on continuous periodic refractive power profile includes: providing an underlying optical correction lens surface curve; defining a periodic power map to provide a correction which optimizes focus based on a use case of a patient, while still providing a functional DoF over a range of distances; mapping the periodic power curve to a physical lens curvature profile; where there is an underlying optical correction, superimposing the physical lens curvature profile over the underlying optical correction; and providing a combination of the underlying optical correction, and physical lens curvature profile to physically manufacture an EDOF ophthalmic eyewear.
