Velocity Sport Classic Collection Sunglasses Gunmetal Frame and Driversreg Gradient Lenses from Serengeti

Featuring a top gradient coating, the Drivers Sienna Gradient lens is the preferred choice of military and commercial pilots. The top gradient acts to block the sun's glare at the top of the lens, while providing a clear view of instruments at the bottom. With a special top gradient coating, the Driversreg Gradient lens helps drivers and pilots fight glare and intense sunlight from above, while allowing a clear view of instrumentation below. Squinting causes optical and facial fatigue. Serengeti lenses relax the eyes by cutting glare and haze. This reduces the chances for early onset of wrinkles, as well as other conditions associated with eye strain and fatigue. A must for pilots and drivers alike.
