I guess my suggestion would be to look around the room to find out for sure! Look at some things at different distances, from close-up to infinity, to see if it makes a difference or has any effect. My question is, how long between when you wake up and notice it and when you get up and it goes away? Are we talking seconds, minutes, an hour?

I've had it happen, but the duration is usually pretty short cuz I don't lie there long upon waking. I've had seldom occasions when it's lasted beyond that - up to a few hours, but there's usually some explanation when that happens. I asked my optometrist about it, and after examining my eyes, he seemed to think it was middle age-related (as long as it didn't stick around).
