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. ## Claims ### Claim 1 An ophthalmic device comprising: at least one ophthalmic lens having at least one base focal length and a base power; and at least one diffractive structure for the at least one ophthalmic lens, the at least one diffractive structure configured to induce a chromatic aberration such that the ophthalmic device transmits a first wavelength of visible light at a first power and a second wavelength of visible light at a second power; wherein a difference between the first power and the second power is at least two diopters, thereby providing an extended depth of focus across a spectrum of visible light between the first wavelength and the second wavelength. ### Claim 2 (depends on 1) The ophthalmic device of claim 1, wherein the at least one focal length includes a plurality of focal lengths such that the at least one ophthalmic lens is a multifocal lens. ### Claim 3 (depends on 1) The ophthalmic device of claim 1, wherein the difference is at least three diopters and not more than five diopters. ### Claim 4 (depends on 1) The ophthalmic device of claim 1, wherein the first wavelength of visible light is at least four hundred ninety nanometers and not more than five hundred and ten nanometers and the second wavelength of visible light is at least five hundred ninety nanometers and not more than six hundred and ten nanometers. ### Claim 5 (depends on 1) The ophthalmic device of claim 1, wherein the first wavelength of visible light is not more than two hundred nanometers from the second wavelength of visible light. ### Claim 6 (depends on 1) The ophthalmic device of claim 1, wherein the at least one base focal length has a base chromatic aberration corresponding for a base chromatic aberration power and wherein a combination of the base chromatic aberration power and the difference between the first power and the second power is at least two diopters. ### Claim 7 (depends on 1) The ophthalmic device of claim 1, wherein the base power corresponds to a base curvature of the at least one ophthalmic lens. ### Claim 8 (depends on 1) The ophthalmic device of claim 1, wherein the at least one diffractive structure is incorporated into an anterior surface of the at least one ophthalmic lens. ### Claim 9 (depends on 1) The ophthalmic device of claim 1 wherein the at least one diffractive structure is incorporated into a posterior surface of the at least one ophthalmic lens. ### Claim 10 (depends on 1) The ophthalmic device of claim 1, wherein the at least one ophthalmic lens is selected from an intraocular lens and a contact lens. ### Claim 11 (depends on 1) The ophthalmic device of claim 1, wherein the at least one ophthalmic lens includes a first lens and a second lens, the first lens having the base power, the second lens having the at least one diffractive structure. ### Claim 12 (depends on 1) The ophthalmic device of claim 1, wherein the at least one ophthalmic lens is a single lens having the base power and the at least one diffractive structure. ### Claim 13 An ophthalmic device comprising: an ophthalmic lens having at least one base focal length and at least one base power, the ophthalmic lens including an anterior surface and a posterior surface, the at least one base power corresponding to at least one base curvature of at least one of the anterior surface and the posterior surface, the ophthalmic lens further comprising a diffractive structure configured to induce a chromatic aberration such that the ophthalmic lens transmits a first wavelength of visible light at a first power and a second wavelength of visible light at a second power, wherein a difference between the first power and the second power is at least three diopters and not more than five diopters, thereby providing an extended depth of focus across a spectrum of visible light between the first wavelength and the second wavelength; and a plurality of haptics coupled with the ophthalmic lens.
