Smith's ChromaPop+ Polarized Captains Choice Sunglasses serve up optical clarity for piloting your boat through bright waters or driving a beater van in sunny deserts. Unlike standard polarized lenses, Smith's patented ChromaPop+ lenses use film-free polarization for permanent glare-resistance. ChromaPop+ also maximizes colors and contrasts for optimal optics, and there are hydroleophobic and anti-reflective coatings to repel water, smudges, oils, scratches, and reflections. The frame features lightweight Evolve material, rust-resistant stainless steel spring hinges, a wraparound eight base curvature, and hydrophilic nose and temple pads for a good grip.
