Whether piloting a plane or speeding down the highway, the Medium Aviator Henna Drivers Gradient Sunglasses from Serengeti deliver the total protection needed for any sunny environment. The gradient tinted lenses offer 24% to 9% light transmittance, making them perfect for all-day wear from sunrise to sunset. Offering more than protection from the sun’s harmful rays, the sunglasses also guard against wind and airborne debris. Contoured frames follow the natural curve of the face, creating a snug comfortable fit that does not pinch or bruise. The adjustable nosepiece creates a custom fit that feels great and keeps the glasses secured in place regardless of activity.
