These are not your father's aviator sunglasses. Oakley's Polarized Square Wire has evolved into its own distinct classification--without compromising the lightweight fit and exceptional optical clarity. The frame edges are squared and more pronounced than the Big Square Wire Sunglasses but the lens coverage is marginally smaller. Like the other Wires the Square Wire offers full UVA and UVB protection with a lightweight and durable C-% alloy frame.
