Finally there is a full reading safety sunglass available at an affordable price. It has always been possible to find safety glasses with a bifocal but very difficult to find the full reading lens. Due to the curvature of the lens in this style the magnified portion does not extend to the curved edges. It does go from top to bottom and does cover the main area of the lens. The lenses are ANSI approved and also 100% UV protected. Frame Measurements: 5 1/4" x 1 1/2" (hinge to hinge x height of lens)
