I agree with impact-resistant eye protection, etc. However, when I read the first post about goggles I wondered if the issue might be smoke/dust/particles in the air. I've worked with survivors of massive explosions (Oklahoma City, and the 911 World Trade Towers) and based on what they told me I go with a simple pair of swimmer's goggles. Tiny, light, easily stuffed in a small fanny pack, etc.

Sure, there are much better larger goggles available. In this application though, I just want to keep krud out of my eyes while I evacuate. On the shooting range or in the workshop, of course I use something else.
