Comfortable, Lightweight Safety Goggles: VS350 safety goggles have a low-profile design, featuring a soft seal that adapts to your face. A wide, fully adjustable head strap offers pressure-free comfort. The innovative indirect ventilation system ensures the environment inside the goggle stays cool and dry instead of heating up, fogging and slipping around on your face Trushield-S Permanent Anti-Fog Coating: Permanent, dual-action anti-fog protection on the interior of the lens and a scratch-resistant hard coat on the exterior of the lens Offers As Close To Natural Vision As Possible: Clear lenses are ideal for most jobs, typically indoors, that include but not limited to general labor, machine operation, lab use, and construction applications 100% UV Protection: All of our work safety glasses, no matter the tint, offer 100% UV protection from harmful rays Increase The Life Of Eyewear: Do not use anti-fog cleaner or solution on lens as that will ruin the coatings. To properly clean lenses use a microfiber cloth only, or rinse with cool water and use a lens safe tissue.
