Grays sunglasses are the ultimate fishing sunglasses featuring the best possible materials at an affordable price. All of our frames contain a high degree of bio material, which has a much lower carbon footprint. The lenses are all polarized shatterproof polycarbonate, and feature a hydrophobic material which reduces water spots and makes for much easier cleaning. The lenses reduce glare significantly, provide maximum UV protection, and the anti-reflective back coating reduces glare reflecting off the back of the glasses, which reduces eye strain.
