Do y'all use these walking around the park in the daytime?  I understand the principles of what they do and how they're used.  I got one to play with, but haven't used it a whole lot.  Wondering if I need to bother with it at all.  I do like the reduced glare that I get with it, and I guess it could protect the lens some.  Just curious if y'all use them or not.
