Auto darkening welding goggles are a type of personal protective equipment (PPE) used by welders to protect their eyes from harmful ultraviolet (UV) and infrared (IR) radiation emitted during welding. Unlike traditional welding goggles with fixed tinted lenses, auto darkening welding goggles feature a specialized lens that automatically adjusts its darkness level in response to the brightness of the welding arc. Auto darkening welding goggles provide welders with enhanced visibility, eye protection, and comfort, making them a popular choice in the welding industry. Welding goggles also include welding glasses.
