Oakley SI Flak Jacket XLJ/PRIZM Replacement Lenses Tactical Reviews, Deals, Problems and Guides

Oakley SI Flak Jacket XLJ/PRIZM Replacement Lenses are designed with professional shooters in mind. Like all Oakley lenses, these block 100% of all harmful UVA and UVB rays and are made with Oakley's HDO Optics for superior visual fidelity and impact resistance. They also feature Oakley SI Prizm technology, which uses formulated dye compounding to produce fine-tuned visual contrast. This technology allows targets to stand out from background objects, like dirt and foliage, and makes reticle patterns under the scope easier to see. It also reduces eye fatigue and strain. For exceptional durability and optical purity, these lenses are made with Oakley's Plutonite material, an optical-grade polycarbonate.
