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.

9. An ophthalmic lens device comprising:
-
one or more refractive surfaces that partially correct a user'"'"'s vision defect; a diffractive waveplate coating with a pattern designed to correct the user'"'"'s vision defects not corrected by the refractive surfaces; a suitable substrate on which the diffractive waveplate coating is deposited, or within which the diffractive coating is contained; and a mechanical feature to securely position the ophthalmic lens device with respect to, or within, the user'"'"'s eye such that the user'"'"'s vision is corrected by the ophthalmic lens device, ophthalmic lens device for correction of human vision, not located on the surface of an eye. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for manufacturing ophthalmic lens devices, comprising the steps of:
-
providing an ophthalmic lens blank with a laminated structure, in which a half-wave thick layer of polymerizable liquid crystal is contained between layers of photoalignment material at the two boundaries of the layer; aligning the photoalignment layers to correspond to a prescription for the correction of vision defects of specific individuals; and photopolymerizing the polymerizable liquid crystal after it has aligned itself with the aligned photoalignment layers. - View Dependent Claims (16)
