Abstract:
In general terms, the lens overlays of the present invention comprise thin, formed plastic overlays that can easily be attached to the inside or outside of the primary protective lenses by the user. In one embodiment, the lens overlay comprises a first overlay to be disposed on the left side lens and a second overlay to be disposed on the right side lens. In another embodiment, the lens overlay comprises a one piece conforming overlay lens that is attached to the front face of the primary lens by removing the frame bridge, slipping the frame temples through a left and right hole in the endpieces of the overlay and snapping the bridge back onto the frame to secure the overlay to the front face of the primary lens. In yet another embodiment directed to lens overlays for eyewear having a frame browbar with the primary lens, the formed overlay of this embodiment is secured primarily to the browbar itself.
