Arc welding produces an intense amount of radiation that requires a darker shade for the lens, and additional protection for the face such as a welding helmet.
Despite the long term damage that radiation can cause, molten and cold metal particles striking the eye are still the most common sources of eye injuries. For this reason, it is critical that you wear protective eyewear at all times when working around welding applications. The grinding and chipping present additional hazards.
Please beware of using 'sunglass' shaded lenses when welding. The visible light may be reduced, which fools your eye into enlarging the pupil opening, allowing more light in than it would if unshaded. However, the harmful infrared radiation will pass through unfiltered resulting in eye damage.

- The Pyramex Integra safety glasses with welding shade lens offer protection from both Ultraviolet (UV) and Infrared (IR) radiation. Standard safety glasses equipped with polycarbonate lens inherently offer protection from UV light. The welding shade option will effectively absorb IR. The decision about what shade (darkness) to use depends on the application. In general, we want to use the darkest practical alternative. At some level, you need to see your work, but the darker lens shades absorb more infrared. So there is a balance. Please remember to never use standard ‘grey’ sunglass shades. For this type of work, they are worse than using clear glasses, as they fool the eye into opening the iris, while IR light pours through.
