Eye injury can occur from the intense light and radiation that a welding arc can produce.  Eye injury can also occur from hot slag that can fly off from the weld during cooling, chipping or grinding.

Protect your eyes from welding light by wearing a welder's helmet fitted with a filter shade that is suitable for the type of welding you are doing.ALWAYS wear safety glasses with side shields or goggles when chipping or grinding a work piece if you are not wearing a welding helmet.
