The Oakley SI Flak 2.0 XL PRIZM delivers maximum visual clarity and eye protection. These glasses are made with Prizm TR45 shooting lenses that are coated in Titanium Iridium to perform in low light conditions. These lenses maintain a casual appearance, create greater visual perception and reduce eye fatigue. They also are treated with anti-fog and scratch-resistant coating to ensure maximum visual clarity at all times. The lightweight, stress-resistant O-Matter frame combines flexibility and strength to withstand impact and environmental extremes. It also uses a semi-rimless design so that no frame rim obstructs your downward view. The glasses exceed ANSI Z87.1 standards for impact and optical protection, guaranteeing durable, long-lasting wear. An interchangeable lens design allows you to choose the exact optical performance you need for a given situation.
