What is the main benefit of using welding goggles during welding?

The main benefit of using welding goggles during welding is to protect the eyes from intense light and harmful rays produced during the welding process. Welding generates a significant amount of bright light, including ultraviolet (UV) and infrared (IR) radiation, which can cause serious eye damage, such as burns or long-term vision impairment. The goggles are specifically designed with lenses that filter out these harmful rays, allowing the welder to see the workpiece clearly while ensuring their eyes are shielded from injury.

While enhancing visibility might be important, the primary function of welding goggles is fundamentally protective. They do not address noise exposure and are not designed to improve breathing in confined spaces, as those concerns are addressed with different types of personal protective equipment. Therefore, the protection of the eyes from intense light and harmful rays remains the crucial reason for using welding goggles.
