ITA - Special edition Italian graphics. UV400 lens rating ensures protection against 100% of UVA, B and C rays. Funky, ultra stylish casual sunglasses. Rubber inserts on nose and ear pieces. RW: Polycarbonate anti-scratch rainbow lenses (RW) undergo a surface mirroring process to reduce light blinding and glare from water, snow and ice. The filtering power of the lenses is greatly enhanced. Hydro repellent lenses undergo a special process making them smoother than any other lenses. This means water and dust easily slide off the lens keeping it clean. These lenses are especially suited to outdoor sports. The inner surface of the lens undergoes an anti-glare treatment. This reduces the dazzle produced by light reflecting off other surfaces. The result is clearer vision and increased colour contrast.
