Designed specifically for marksmen of every level, from recreational to elite, the Oakley SI Flak Jacket XLJ PRIZM uses special lenses designed to improve your aim. Oakley's durable Plutonite lenses are held in place by a three-point fit for precise optical alignment and are made with Oakley SI Prizm technology. This technology uses a formulated dye compound to deliver a color-tuned lens made to block specific wavelengths on the color spectrum to enhance recognition of the target while minimizing backgrounds such as trees and sky. This improves target acquisition and minimizes eye fatigue. The frame is made from Oakley's lightweight, stress-resistant O-Matter frame material for non-stop comfort and features an Unobtainium nose pad to keep the glasses in place, even when wet. These glasses also meet multiple safety standards and block UVA and UVB rays.
