Engineered to provide distortion free optics, ESS lenses are 100% optically correct and ANSI Z87.1-2010 compliant, while at the same time providing 100% UVA/UVB protection.
High adrenaline goggle users demand maximum fog resistance. The inner surface of all ESS goggle lenses is coated with ESS Clear Zone™, an advanced fog-repellent treatment impregnated in the lens for long-lasting performance. ESS Tough Zone™ anti-scratch coatings help armor the lenses against all sorts of scuffs, scratches and abrasions. ESS lenses are 2.2mm to 2.8mm of thick polycarbonate - tough enough to stop a shotgun blast and pass the rigorous US Military .22 caliber ballistic impact test MIL-V-43511C. Independent test labs show that ESS lenses have V50 impact ratings of up to 727 fps.
