Welders wear special glass goggles or face masks with glass windows to protect their eyes from large amout of ultraviolet rays produced by welding arcs. Frequency range of ultraviolet radition is from 7 × 10¹⁴ Hz to 5 × 10¹⁷ Hz.

Welders wear special goggles to protect their eyes from ultraviolet (UV) radiation and infrared (IR) radiation. UV radiation has a frequency range of 8 × 10¹⁴ to 3 × 10¹⁶ Hz, while IR radiation ranges from 3 × 10¹¹ to 4 × 10¹⁴ Hz, both of which can harm the eyes.
