1. An optical device comprising:
an optical component having a uniform thickness and configured to modify a wavefront of a light beam that includes light in two or more wavelengths visible to human eyes, wherein the optical component has a chromatic aberration between the two or more wavelengths; and
a metasurface on the optical component, the metasurface including a plurality of nanostructures configured to modify respective phases of incident light at a plurality of regions of the metasurface,
wherein the plurality of nanostructures is configured to, at each region of the plurality of regions, add a respective phase delay for each of the two or more wavelengths to correct the chromatic aberration between the two or more wavelengths.
