Wear over the top of your eyewear glasses or by themselves. These fit straight across the front of your glasses and they look like regular sunglasses. The lenses are non polarized, polycarbonate, UV400 and scratch resistant. The advantage of non polarized lenses is that they do not interfere with reading your digital devices outside or many of the new high tech car dashboards. This style frame fits people with an average to big size face with medium to slightly big size glasses. Your glasses must be smaller than 5 5/8 Inches Wide x 1 7/8 Inches Height. All of our sunglasses come with a Sunglass Rage lens cleaning carrying pouch.
