Abstract: An ophthalmic lens comprising an anterior surface and a posterior surface, at least one of the anterior surface and posterior surface including a first surface region corresponding to a photopic aperture of a pupil and a second surface region corresponding to a difference between the photopic aperture and a mesopic aperture of the pupil. A first microstructure pattern formed in a the first surface region, the first microstructure pattern introducing a phase perturbation into an optical path of incoming light such that a full depth of focus for photopic vision is provided.

Abstract: A method and system provide a multifocal ophthalmic device. The ophthalmic lens has an anterior surface, a posterior surface and at least one diffractive structure including a plurality of echelettes. The echelettes have at least one step height of at least one wavelength and not more than two wavelengths in optical path length. The diffractive structure(s) reside on at least one of the anterior surface and the posterior surface. The diffractive structure(s) provide a plurality of focal lengths for the ophthalmic lens.

Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, at least one diffractive structure and at least one base curvature. The at least one diffractive structure for provides a first spherical aberration for a first focus corresponding to at least a first focal length. The at least one base curvature provides a second spherical aberration for at least a second focus corresponding to at least a second focal length. The first spherical aberration and the second spherical aberration are provided such that the first focus has a first focus spherical aberration and the second focus has a second focus spherical aberration. The first focus spherical aberration is opposite in sign to the second focus spherical aberration.
