The world is your playground, so see it the way it was meant to be seen with the Smith Dolen Sunglasses. Techlite Glass TLT lenses straightens out incoming light rays to eliminate visual distortion and reduce eye fatigue, so you see the world exactly how it appears. Its photochromic performance lets you wear these sunglasses from dawn to dusk, with sunny skies or stormy weather overhead, and expect happy, healthy vision all day. An anti reflective coating eliminates any unwanted reflections, and a hydrophobic coating repels moisture on rainy days. Smith's lightweight Evolve frame uses eco friendly materials, and Out Of Sight spring hinges work in such a way that's honest to its title. Hydrophilic Megol pads make sure the sunglasses don't slide down your nose or your temples.
