Steve,
Definitely get your eyes checked, just in case. You just came from Florida, though, right? This time of year there are all kinds of mold spores, pollens and other things floating around there. I had the same type of problem a couple of time while living there (esp. in the winter months) and it turned out just to be from those nasty culprits I mentioned. (See why I hated Florida so much?)
