DURABLE FRAME: The SABER ADVANCED is the epitome of adaptability. It has a semi-rimless, high wrap design with adjustable telescoping temples and an adaptable, rubberized nosepiece for full protection and comfort, while also being NVG compatible. LENS: The yellow tint is a great light enhancing shield. It reduces glare by filtering out the blue light, while simultaneously enhancing contrasts, when used in low light, overcast, or foggy conditions, making it highly preferred among hunters. SABER ADVANCED ensures that you never have to settle for average. Functionality and durability are fused together in a lightweight design, making them perfect for shooting, hunting, running, cycling, skiing, and most outdoor sports. UNPARALLELED PROTECTION: The lens gives 100% protection from UV/UVB. It is tested to meet the ANSI Z87.1 and EN.166SF safety standards, while also being tested to meet the MIL-PRF-32432(GL) ballistic standard, ensuring a superior quality and safety. TECH AND PRESCRIPTION: The lens is treated with a hard coating, ensuring scratch resistant lenses. Additionally, almost all sunglasses and eyewear from Wiley X can be made with prescription lenses.
