HYDROFOBIC POLARIZED LENSES Summer Sunglasses Blaze by Cressi were created to protect your vision around the water. The Cressi BLAZE solar filters protect 100% against UV rays, block reflected light, and ensure sharp, high-contrast vision. The lenses are made using shatterproof organic glass, an ideal material famous light weight and resistance to blows. The polarized filters further improve vision. The HTC treatment layer makes the lenses water-repellent and keeps them clean. Thanks to the protective HTC (Hydrophobic Tech Coating) treatment, droplets of water slide from the surfaces, leaving them free of streaks and dirt. This protection makes the lenses more durable and long-lasting, for sharp and defined vision.
