Abstract: An aerodynamic eyeglass lens piece which integrally combines a central inboard transparent section with laterally outboard mirror sections, thus enabling a forward facing user to see objects in front as well as behind. The lens piece sections form one agonic lens piece comprising: a light transmissive transparent section and fully reflective mirror sections. The mirror sections have an anatomical shape permitting unhindered over the shoulder viewing for bicycle riding. Several enhancements allow the lens piece to be interchangeable with tinted or clear alternatives. In the preferred eyeglass embodiment of the invention, the lens piece is selectively adjustable to a variety of operative positions. These enhancements serve to provide added versatility, fine tuning and custom fitting for the user. An alternate embodiment fits the lens piece to the existing sport helmet of the user.
