Yes, blurriness that varies throughout the day. My eyes are very dry, so I wonder if that is a big part of the problem. Over-the-counter eye drops help but of course do not cure the problem.

Yes. meds for 'dry eyes.'

Not my actual eye, but the bag right below the right one has started trembling a bit last night off and on and has been a bit puffy

Yes indeed! My vision varies. Sometimes I can read the forum. Sometimes I can’t.
