Why are goggles or face shields important when welding or brazing?

Goggles or face shields are essential in welding or brazing primarily to protect against UV light exposure. During these processes, intense arcs are generated that emit ultraviolet (UV) radiation, which can cause serious eye damage, such as burns to the cornea and long-term vision problems. The protective gear is specifically designed to shield the eyes from this harmful radiation, ensuring that workers can perform their tasks safely without risking their eyesight.

While improving vision and reducing glare are also considerations in selecting protective eyewear, they are secondary to the critical function of UV protection. Additionally, although preventing fume inhalation is an important aspect of safety in welding and brazing, it is more typically managed with respiratory protection rather than goggles or face shields. Thus, the primary reason for wearing goggles or face shields in these operations is their crucial role in safeguarding against UV exposure.
