Abstract
Ophthalmic lenses and related methods employ subsurface optical structures with enhanced refractive index distributions. An ophthalmic lens includes a lens body and a subsurface optical structure within the lens body. Sub-volumes of the optical structure have refractive indexes that vary spatially between a first limit refractive index for the optical structure and a second limit refractive index for the optical structure. The refractive indexes are equal to the first limit refractive index for the optical structure over a first section of the optical structure. The refractive indexes are equal to the second limit refractive index for the optical structure over a second section of the optical structure.
