摘要： An ophthalmic lens includes a hybrid plano-convex refractive lens body having a convex portion and a planar portion. A metasurface array can be associated with the planar portion and include an arrangement of metasurface building elements dimensioned from an optical wavelength. The metasurface building elements can be configured across the lens body to define an optical characteristic of the ophthalmic lens. The arrangement of metasurface building elements can include meta-atoms that are configured to induce a polarization-dependent focusing of light received by the ophthalmic lens. A shape of the meta-atoms of the array can be determined based on a function of the ophthalmic lens, including glare/halo reduction. The meta-atoms can be formed as canonical and/or freeform shapes.
