Abstract: An ophthalmic lens is provided, comprising an optic comprising a first surface, a second surface, and an optical axis. The first surface comprises a first zone extending from the optical axis to a first radial boundary. The first zone comprises an inner region having a first curvature and an outer region having the first curvature. A second zone extends from the first radial boundary to an edge of the optic and a phase shift feature comprising a first phase shift step extending from the first surface. A second phase shift step extends from the first surface, and an elevated lens segment extending between the first phase shift step and the second phase shift step.

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, a refractive region having the base curvature, and a diffractive region comprising a diffractive profile including a plurality of diffractive steps. At least a portion of the diffractive profile constitutes a combination of a base diffractive profile defining multiple foci for the ophthalmic lens and an achromatizing structure that reduces longitudinal chromatic aberrations.

At least one of the anterior surface and the posterior surface comprises a first zone extending from the optical axis to a first radial boundary, and a second zone extending from the first radial boundary to the edge of the optic. The first zone comprises an inner region and an outer region having a first curvature. A phase shift feature separates the inner region and the outer region. The phase shift feature comprises a ridge of increased thickness relative to an adjacent portion of the inner region, the ridge comprises a ridge surface, a first phase shift step extends outwardly from the inner region to the ridge surface, and a second phase shift step extends inwardly from the ridge surface to the outer region.

Abstract: An ophthalmic lens includes an optic having an anterior surface with an anterior surface radius of curvature (R1) and a posterior surface with a posterior surface radius of curvature (R2). The anterior surface radius of curvature (R1) and the posterior surface radius of curvature (R2) define a shape factor (X) (where X = (R2-R1)/(R2+R1)) that is greater than zero. The shape factor (X) corresponds to a curve defining shape factor (X) as a function of lens power (P), the curve monotonically decreasing with increased lens power (P).
