These are the sunglasses that adjust to changing light conditions so you can finish a golf round at dusk or enjoy a walk at dawn without straining eyes. The sunglasses have light-enhancing amber-pigments inside the lenses that brighten surroundings and improve clarity in low-light conditions. The copper-tinted lenses are impact and scratch-resistant and have an optical grade anti-reflective coating that eliminates glare and reduces eyestrain. The lenses block UV-A and UV-B plus scattered blue-light rays for enhanced clarity and definition. With a lightweight stainless steel frame, smooth rubber temple pads, and a travel case. 5 1/4" W x 2 1/4" D. (4 oz.)
