Abstract
An ophthalmic device includes at least one ophthalmic lens and at least one diffractive structure for the at least one ophthalmic lens. The ophthalmic lens(es) have at least one base focal length and a base power for a first wavelength of visible light. The diffractive structure(s) have a chromatic aberration such that the diffractive structure(s) have a first power for the first wavelength of visible light and a second power for a second wavelength of visible light. A difference between the first power and the second power is at least two diopters.
