摘要
Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing dysphotopsia effects, such as straylight, haloes and glare, in diffractive lenses. Exemplary ophthalmic lenses can include a diffractive profile that distributes light among a near focal length, a far focal length, and one or more intermediate focal length. The diffractive profile provides for minimized or zero step heights between one or more pairs of diffractive zones for reducing visual artifacts.
