IOL with varying correction of chromatic aberration

A monofocal ophthalmic lens having an optical power, comprising:

• an optical filter operable to filter out at least light having a wavelength below 450 nm;
• at least one central monofocal diffractive structure having a radius within a selected pupil size for photopic conditions, wherein the at least one diffractive structure is configured to correct longitudinal chromatic aberration to less than one diopter in a wavelength range corresponding to peak visual receptivity for photopic vision;
• and
• a monofocal optical region outside the radius of the first diffractive structure having the optical power, the optical region configured to allow longitudinal chromatic aberration in an amount greater than the longitudinal chromatic aberration allowed by the at least one diffractive structure, wherein the longitudinal chromatic aberration allowed by the optical region shifts light energy from a peak visual receptivity for photopic vision toward a peak visual receptivity for scotopic vision and the longitudinal chromatic aberration allowed by the optical region is less than one diopter in a wavelength range corresponding to the peak visual receptivity for scotopic vision.
