Abstract
Lenses, devices, apparatus, systems, methods of manufacturing and fabricating an ophthalmic lens device for correction of human vision. The ophthalmic lens device includes at least one diffractive waveplate coating with an optical axis orientation pattern designed to correct the vision of individual patients. The ophthalmic lens device including diffractive waveplate coating may also provide a portion of the required vision correction by means of refraction of light by curved surfaces of a dielectric material.
