Sure they help protect from scratches. I could also wear a hard hat all
day to protect me from falling leaves. Someday the hard hat might be
useful, but I don't bother. I do bother with a helmet on my motorcycle. I
don't bother with a "protective" filter for my lenses.
It will degrade the image a little (at least in my experience) but not a
lot. If it makes you fell better or if you have some special need (like
protection from squirrels dropping nuts on your head) then do it. It is not
likely to hurt.
