Eyepieces and cold weather observing.

During cold weather observing, is it better to keep your eyepieces warm
(e.g., by keeping them in your pocket) so the heat from your face
doesn't fog them, or let them equilibrate to the air temperature as the
rest of the scope does? I have only a few (Plossls, not those monster
big ones like Naglers -- not that they aren't on my wish list) so a
coat pocket could be an an option for me.
