1. An assembly, comprising:
a curved waveguide;
a first ultraviolet (UV)-light-reflecting coatings and/or films disposed on the curved waveguide;
a second UV light-reflecting coatings and/or films disposed on the curved waveguide;
at least one UV emitter configured to emit UV light in to the curved waveguide between the first and second UV light-reflecting coatings and/or films;
at least one conversion element in the curved waveguide and disposed to receive the UV light from the UV emitter, the conversion element being configured to convert the UV light in to visible light that propagates through one or both of the first and second UV light-reflecting coatings and/or films and that impinges on the eye of a wearer of the curved waveguide; and
at least one lens juxtaposed with the conversion element through which the visible light emitted by the conversion element is focused.
