Presenting all-new Oakley Sliver sunglasses. Clean lines and keyhole bridge bring a contemporary edge to their retro shape. Plus this Covert Collection edition looks timelessly cool in polished black. Gaze through its Plutonite lenses. The view is amazingly clear. And everything shows up without distortion because XYZ Optics stop light from skewing. Look through any part of the lens – and its you'll get the same sharp, high definition picture. Every lens gives the greatest impact resistance.

This one features new Prizm Daily Polarised lenses. So you'll see detail like never before. Because Prizm lenses amplify and fine-tune colours like an equaliser. Now contrast is astonishing while colours are vivid. This one features polarised lenses. So glare is blocked out. And Oakley builds polarisation into the lens (there's no glue to obscure vision here).

HD Polarised lenses are cut from the same Plutonite sheet. This means light passes through each one at the same point. This cuts out distortion. Glare from all angles is blocked while eyes no longer strain to see. They can relax. Wear these Oakley sunglasses all day – they're so comfortable because they're made from lightweight O-Matter. But it's built to last too. And Three-Point Fit means there's no uncomfortable pressure points. Sliver fits medium to large faces brilliantly. All lenses block 100 per cent of UVA/UVB/UVC rays and blue light up to 400 nm. Oakley sunglasses come with a one year warranty.
