These are the multi-coated sunglasses that provide a dozen protective and vision enhancing benefits. Triple filter polarization--developed from NASA optic technology--blocks 99.9% of harmful UVA and UVB rays, as well as damaging blue and violet wavelengths and enhances contrast for hawk-like clarity. An optical-grade anti-reflective coating cuts distracting glare. Scratch- and crack-resistant coatings protect each side. Separate coatings repel water and dust, and reduce smudges, helping to maintain visual acuity during active pursuits. The contoured flash-mirrored lenses are set in a lightweight aviator-style metal frame that has soft silicon nose pads for a comfortable fit. Includes a zippered case and microfiber cleaning pouch.
