Greys 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 polarised 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.
