Swimming goggles fully protect the eyes from dust and debri that may be in the air in a building collapse etc. Remember some of the people exiting WTC buildings were essentially blinded by dust etc in the eye. Water was needed to flush out their eyes, and that was in short supply in the immediate area.

Safety goggles will not prevent this prevasive dust from getting to the eyes. I still need to add a pair to my daily carry bag, but not my other kits.
