It could be exposure keratitis due to the lids separating slightly during sleep or it could be maile recurrent corneal erosions.These two problems can co-exist. use the search feature to look up previous discussions.
Try genteal gel in both eyes at bed time, in am splash eyes with warm water then put in a good artifical tear like systane or opteve.

Thanks so much! I got the gel you recommended the first day you posted it. I was surprised that first night after using it that I could tell some difference that quickly! The eye that has been the longest not opening when I wake up is still having some problems opening but not as bad and the other eye that just started having problems is a lot better already. It's a great relief to be able to have atleast one eye to open up while the other one hopefully will be all better, too, soon. Again, I really did not expect any relief that quickly so it was a nice surprise. Thanks again and for taking time to be here to answer our questions.
