You can make the weirdest dance moves ever performed and still look cool in the Smith Polarized Drake Sunglasses. Bounce imaginary balls or do the shopping cart, and everyone watching won't even notice how bizarre your moves are, because the Drakes' style memorizes everyone on the dance floor. Techlite polarized glass lenses are Smith's clearest glasses available, and they're scratch resistant. not only do they eliminate glare from the strobe lights, but they also redirect reflections for a more comfortable wear. Smith made the Evolve frame out of partially eco friendly materials. The blue mirror lenses work best on water, and the green mirror lenses look best on land.
