The Smith Scientist Sunglasses are the smart choice for those looking at performance eyewear. Constructed in a light TR90 Grilamid frame with metal eyewire holding the lenses, these Smith glasses stand up to the rigors of your day to day. Featuring TLT Polarized glass lenses, the Scientist sunglasses protect your eyes from harmful UVA/B/C rays while keeping your vision distortion free, and reduce glare to keep you seeing clearly. With a 6 base lens curvature, the Scientist glasses offer a traditional wrap style perfect for big city action. Stainless steel spring hinges allow these Smiths to fit a large range of head shapes. Should you find yourself out when rain starts falling, the hydrophobic lens coating prevents water from streaking the lens of these Smiths so you see clearer. It doesn't take a rocket scientist to figure out how great the Smith Scientist Sunglasses truly are.
