12 wrap-around safety glasses: These safety glasses have been tested and comply with standards. They are also resistant to UV radiation, corrosion and fire. As these goggles wrap around the face, they fit securely on women, men and children and will not slip off. Safety glasses stay in place: these safety glasses have an orange rubber grip on the bridge of the nose and on the end of the arm located behind the ear. This ensures that the glasses stay firmly on your face even when you are working face down. This stops debris and dust getting into your eyes. Scratch-resistant, clear, tint-free lenses: each lens is scratch-resistant, which means they won't be easily damaged and will protect your eyes well for years to come. Each pair of lenses is protective against high-speed, low-energy particles and passes through lateral protection, so your eyes will stay safe. Can be used for work and play: this bulk set is ideal for woodworking and carpentry, metal and construction work, laboratory and dental work, mechanics, cycling, cleaning, painting, squash, archery, cycling or anywhere you need to wear glasses. They can even be used in Nerf gunfights and water balloon fights.
