Fitted with a bi-gradient lens, your eyes will be protected from reflected glare from every angle with this superior lens technology. A bi-gradient mirror is fitted to top and bottom of the lens, creating a squint affect for the mirror in the middle to block out excessive light coming through. This style is perfect for those that live an active life outdoors.
