Is it possible for the sight to improv e quickly? Yesterday I had one of my worst days ever, sightwise, with problems all day long but this morning, when I awoke, I could see much better, in fact, I felt as though I would be able to drive again. I had a sight test which showed that I could read two lines further down than I normally could (but only half the line, i.e. the first two or three letters not the 4 or 5 required). I am feeling tremendously bucked up by this but at the same time trying not to get excited in case it's a blip.
