PiWear Pi RC2 sunglasses are perfectly round, and available in 8 color combinations. This frame has a smaller lens and is a bit wider than the 2PiR sunglasses, and are better for wider faces. Everyone should have a couple pairs of round sunglasses in their wardrobe, for those days when your confidence, style, and intelligence must be communicated to the world. All Pi RC2 sunglasses come with polycarbonate lenses, with backside anti-reflective coating, and 100% UV protection. Not only will you look great, but your vision through these lenses will be unsurpassed. Like all PiWear eyeglasses and sunglasses, when you buy a pair, you make a blind person see - literally.
