This safety eyewear is designed to fully protect your eyes from environmental hazards, fully enclosed with anti-moisture vents. The PC material is light and tough; it does not sink when worn, is anti-twist, super tough, can be arbitrarily bent, not easy to break. Effectively prevents dust, wind, sand, and impact; prevents spray of saliva spray; isolates and protects; and protects eyes. The surface of the PC lens has been specially strengthened many times to prevent friction and impact. The curved design of the lens makes the field of vision wider, clearer, and more durable. It's easy to see why it's lightweight, stronger than plastic, impact-resistant, and has better resistance than other materials, too. Polycarbonate frames and lenses are most common for a reason: they work really, really well. Safety glasses should protect your eyes and remain comfortable enough that you'll actually wear them. Polycarbonate checks both boxes. Key Features 1. Impact resistant; lightweight; clear lens; protective coverage 2. Full-coverage eye protection 3. Adjustable headband 4. One size fits all 5.
