ELI5:Why do we never have any mist in the eyes during a sudden temperature change?

Excuse me for my english, this is not my first language.

Are you asking why eyes don't fog up like glasses do when you go from cold to warm and humid? 

That's because our eyes are already warmed by our body so they aren't really at condensing temperatures, also there are wet so any condensation that formed would just become part of the film of water that covers our eyes anyway.
