Foster Grant Navigation sunglasses for men are designed for driving. When you're behind the wheel they provide enhanced contrast, depth and color perception. Driving sunglasses are unique because they feature a special AR (Anti-Reflective) coating. This is coated on the backside of the lens to prevent bounce back glare from reaching the eye, ensuring sharper driver acuity and enhanced clarity. They also help to reduce eye fatigue, which enables you to maintain visual alertness in harsh light conditions. Smoke colored lenses and lightweight frame and temples combine for sunglasses that feel comfortable for even long drives. And because they're Foster Grants, they offer full UVA/UVB ray protection as well as excellent scratch and impact resistance. Enjoy the ride!
