Frame: - Lightweight and flexible, our featherweight Grilamid® injected frames are impact resistant and maintain high flexibility. Our Sport Line features dual-action hinges, sunglass leash holes, featherweight construction, flexible impact-resistant frames and non-slip nose pads. Blue Polarized Pro lens: - The Blue Polarized Pro lens blocks 99.9% of debilitating glare from the water's surface. HEV blue light is reduced by 98% plus you get 100% UV protection, superior color contrast haze-free vision, and reduced eye fatigue. All with the added benefits of anti-reflection, hydrophobic (repels water and sweat), oleophobic (repels oil and dust), and flash-mirror performance lens coatings. - Lens material: All of our Grilamid frames use Bayer Makrolon® raw Polycarbonate material for our lenses. These lenses are lightweight and impact resistant. - Hard coating: A double-sided coating that reduces minor scratching. Offered as a standard treatment on all lenses. - Anti-reflective coating: Reduces reflections off the back surface of the lens which increases contrast. - Hydrophobic coating: Life on the water or life in the heat often means your glasses get hammered with condensation. Our hydrophobic coating helps repel these elements and fights against water and sweat. - Oleophobic coating: Oil and dust have met their match. A double-sided coating repels sunscreen and more; smudges clean off easily. - Mirror coating: Cosmetic treatment applied to the exterior of the lens. - VLT: 11,5%
