  • Patent number: 12339525
    Abstract: An ophthalmic lens includes an optic with a first surface, a second surface, and a phase-shift structure having one or more phase-shift regions. A method for fabricating an ophthalmic lens includes designing an optic with a first surface, a second surface, and a phase-shift structure having one or more phase-shift regions. The phase-shift regions may be adapted to generate respective chromatic focal shifts such that an incident radiation in a respective wavelength range at least partially converges towards a respective selected wavelength. The method includes determining a chromatic aberration target for the optic and determining the quantity of the phase-shift regions meeting the chromatic aberration target. The optic is formed with the phase-shift regions having respective optimal heights obtained based in part on an overall interaction effect. The phase-shift structure may be adapted to increase a depth-of-focus of the optic in the direction of extension.
