These versatile sunglasses are perfect for both day and night use. The polarized lenses filter out glare whether you're driving long distances or enjoying outdoor sports. The photochromic technology allows the lenses to automatically adjust based on lighting conditions, darkening in bright sunlight and returning to clear when indoors or overcast. The semi-rimless design provides unobstructed peripheral vision so you can keep your eyes on the road or trail. Lightweight yet durable, the frames are comfortable enough for all-day wear. These driving glasses offer 100% UV protection and help reduce eyestrain when visibility is low. An ideal choice for cycling, hiking or any activity where protection from sun and glare is important.
