Originally implemented in acetate by Persol, American eyewear company Ray Ban has now released a new set of folding metal frame shades.

The latest round metal's are an upgrade from last fall, as they now come in a range of coloured mirror lenses for 2015 as well, including a cool matte-gunmetal. The 1930's-style sunnies feature a lightweight frame, curved brow bar and adjustable nose pads giving the accessory the ultimate in comfort and eye-catching appeal.
