Polarized antireflection lens reduces reflections of horizontal surfaces - 100% UV protection - The Hydrophobic coating works by making a surface of your lens to repel the water molecules remaining on them, which means that the hydrophobic coating weakens the surface bonding among the water drop and surface of the lens. This lets anything based on water ( rain, sweat, etc. ) to stay away from lens surface. Lightweight and Windproof Ergonomic design, in combination with polarized lens, is ideal for usage by cycling, watersports, driving, running, fishing, racing, skiing.
