Abstract
An assembly for attachment to the bill of a cap comprises a curved lens panel, and a pivot member to receive the lens and attach it to a frame. The pivot member includes a lens retaining member formed by a curvilinear wall that extends from the body, and the body's curved ends form receptacles that receive the lens panel's ends; the lens panel can be readily inserted and removed, enabling the user to interchange lenses, using different styles, colors, or prescriptions. The pivot member includes a hinge enabling the lens to be pivoted into several positions, and a middle member connecting the lens retaining receptacle with the hinge. The frame has curved ends which form a gripper opening for receiving the bill of a cap, and a barb which engages the bill. Screws threaded through the frame ends also aid in attaching the eyeglass assembly to the bill.
