Why do welding goggles have such dark lenses? That nearly black lens isn't simply there to block bright light. Welding produces intense radiation, so specialized filters are designed to reduce the amount reaching the eyes while still allowing welders to see their work.
In this video, we explore why welding lenses are so dark, why different jobs require different shades, how auto-darkening helmets work, and why ordinary dark glasses aren't enough for welding.
