These plastic revo-lens unisex Oxigen wayfarers take the classic look of sunglasses with black frames and turn it on its head. There are so many options available for people who want an ordinary pair of black sunglasses. The only difference comes when they decide that they would rather wear something a little more adventurous. You might not think the color of the lenses in a person's shades will make a difference. On the contrary, more people look at the lenses on a person's sunglasses than the frames. If the lenses are engaging, the rest of the sunglasses will become more engaging as a result.
