*NOTE - Welding Safety Glasses and Goggles using Shade 5 filters or lighter are not intended for arc welding, which requires a darker lens found in Welding Helmets (OSHA's 29 CFR 1910.252 lists the minimum lens shade requirements for a variety of welding operations).
Welding protection with IR Green shades, Cobalt, or other very dark lenses is NOT to be worn while operating moving vehicles, bicycles or any such apparatus, particularly on the road, as these shades can significantly impair one's ability to see traffic signals adequately or accurately. "Welding protection" includes, but is not limited to: glasses, goggles, shields, masks, hoods and helmets. Safety Glasses USA, Inc. is not responsible for any damage or injury caused by such activity.
