Unlike conventional sunglasses, the Oakley Fives Squared Prescription Sunglasses use Condensed Cranial Geometry with dimensional reliefs for a better fit. Available in Polished Black and Gray Smoke, this frame also features High Definition Optics®. In other words, the lenses are tested under extreme high mass and high velocity circumstances to ensure uncompromising protection across a wide range of demanding conditions. Plus, the Oakley Fives Squared Sunglasses are prescription available. For more options check out our Oakley Sunglasses Collection.
