Abstract
An eyewear assembly comprises a primary lens assembly including a primary frame that secures a pair of primary lenses in position relative to one another. A pair of extensions is provided, each of the extensions positioned on an outer periphery of the primary frame. An arm is connected to each extension by a hinge. A safety shield is carried by the eyewear assembly and extends around a portion of the periphery of one of the primary lenses and extends longitudinally along one of the arms, wherein an open space between the primary lens, the arm, and an eye of the wearer is substantially enclosed. The safety shield has an aperture formed therein that extends from the primary lens rearward proximal the hinge, wherein the aperture is adapted to receive a portion of an auxiliary lens assembly.
