Ophthalmic lens assemblies and methods of assembly and use

摘要

Ophthalmic lens assemblies and methods of assembly and use may include a lens assembly including a lens element and a protective cover. The lens element includes a contact lens surface and a faceted optical body including a distal portion and a faceted portion including one or more mirror facets to form a TIR activity pathway. The protective cover includes a contact aperture shaped to receive the contact lens surface, a grip portion, and a facet housing portion including an interior surface. The contact aperture of the protective cover is stretch-fit about a periphery of the contact lens surface to maintain a proximal-side fluid seal. The grip portion of the protective cover is stretch-fit about the distal portion of the lens element to maintain a distal-side fluid seal. One or more TIR-inducing air gaps are defined by the facet housing portion between the interior surface and the mirror facets.

主权项

1. A lens assembly comprising a lens element and a protective cover, wherein:
the lens element comprises a contact lens surface and a faceted optical body comprising a faceted portion and a distal portion; the faceted portion is disposed between the contact lens surface and the distal portion; the faceted portion comprises one or more mirror facets comprising respective one or more internal, optically reflective facets and one or more external facets disposed opposite respective internal, optically reflective facets; the one or more internal, optically reflective facets comprise respective one or more total-internal-reflective (TIR) surfaces; the one or more internal, optically reflective facets and the contact lens surface form a pathway for TIR activity; the protective cover comprises a contact aperture shaped to receive the contact lens surface, a grip portion, and a facet housing portion comprising an interior surface and disposed between the contact aperture and the grip portion; the contact aperture of the protective cover is stretch-fit about a periphery of the contact lens surface to maintain a proximal-side fluid seal; the grip portion of the protective cover is stretch-fit about the distal portion of the lens element to maintain a distal-side fluid seal; and one or more TIR-inducing air gaps are defined by the facet housing portion of the protective cover between the interior surface of the facet housing portion of the protective cover and the one or more external facets of the faceted portion of the faceted optical body.
