Does welding ruin your eyes?

All the main types of welding produce ultraviolet, visible spectrum, and infrared radiation. Since reflected light can also carry radiation, your eyes can be damaged from the arcs of other welders, too. Ultraviolet radiation (UVR) in particular gets absorbed in the lens and cornea and leads to swollen, painful eyes.
