Polarized lenses are very helpful for reducing glare and giving the image more clarity. All of our lenses are 100% UVA and UVB resistant to keep you protected from the harmful rays of the sun. These glasses have adjustable nose pads that you can bend whichever way to have a comfortable customized fit for your face.
