Most definatly not... in fact it was a pita keeping moisture out of them.
Heres an interesting periscope operating manual link. Check all the chapters on "fogging".

They weren't? Good Lord, I thought all quality scopes were fluid filled....I guess "quality" being the key word here...:p

However...
It is standard peacetime doctrine when surfacing in known shipping lanes to raise the scope while you are still well under to check for "shapes and shadows". The surface duct can be very squirrley in re. picking up ships that are close aboard, so a visual check is almost always done during a normal surfacing evolution.

For me, this says it all. This is all I need to justify using the scope to keep track of destroyers directly above me. Please bear in mind that I AM an expert on the subject, as my wife keeps telling me so. :p
