What type of eye protection is considered unsuitable for welding radiation?

Clear safety goggles are considered unsuitable for welding radiation due to their inability to adequately filter harmful UV and IR radiation produced during welding operations. While these goggles provide some level of eye protection, they lack the necessary tinting to shield the eyes from the intense light and radiation generated by welding arcs. This can lead to eye injuries, including photokeratitis or "welders' flash," which is a painful condition caused by overexposure to UV radiation.

In contrast, welding goggles and face shields are specifically designed with filters that block out this harmful radiation while allowing the welder to see clearly. Sunglasses, depending on their tint and UV protection rating, may not provide sufficient protection either, but they are generally considered less suitable than dedicated welding protection like goggles or face shields. Therefore, in the context of providing safe and effective eye protection while welding, clear safety goggles do not meet the required standards and are ultimately unsuitable for this type of work.
