Smith Optics Lowdown Sunglasses (Impossibly Black - Blackout Carbonic TLT)

Don't let the sleek and classic style of the Impossibly Black frame Lowdown Sunglasses from Smith Optics distract you from the performance features designed into them. The Blackout dark gray lens tint offers 100% protection from UVA/B/C rays, cuts glare, and reduces eye fatigue in very bright, exposed sunny conditions. It is especially effective at altitudes where bright conditions can become exponentially more powerful from the glare created when powerful mid-day sun reflects off snow. The Lowdown's scratch and impact-resistant lenses are made using Tapered Lens Technology (TLT) which corrects the distortion common in curved lenses by progressively changing the thickness of the lens from the optical center.
