Abstract
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.
