12 PCS GOGGLES: These goggles have been tested and conform. They also block UV rays, are corrosion-resistant and protect against flying sparks. Because these goggles reach behind the ears, they fit both women and men and even children securely and firmly without slipping. See image for full dimensions. WELL-FITTING EYEGLASSES: These goggles have an orange rubber insert on the bridge of the nose and on the end of the temples behind the ears. This means that the glasses are guaranteed to stay firmly on your nose even when you bend down during work. Dust and small parts are also kept out of your eyes thanks to the non-slip fit of the glasses. TRANSPARENT NON-TINED LENSES THAT WILL NOT SCRATCH: Each lens is scratch-resistant, so it won't break easily, but perfectly protects your eyes for many years. Each safety goggle also protects against small parts flying around at high speed and pressure and has also been side impact tested so your eyes are always well protected. USE FOR WORK AND LEISURE: Our bulk pack of lab goggles is ideal for woodwork and carpentry, metal and construction work, laboratory and dental work, mechanics, cycling, cleaning, painting, badminton, archery and anywhere PPE equipment is needed to protect the eyes. They can even be used for Nerf gun play and water balloon battles.
