Our blue sport HD sunglasses feature our thinnest TR90 half frame - they have an especially snug, lightweight fit. The lenses are unobstructed by the design -- the Storm is virtually frameless with our narrowest rectangular HD lenses for the ultimate low-profile look. The amber HD sunglass lenses enhance your ability to see depth and contrast, objects are more sharply defined, and colors are bright and vibrant. HD lenses are great for an active lifestyle. 100% UV protection, Half frame design, Grilamid® TR90 plastic polymer frame, Rubber nose pads, Inlaid metal logo.
