I think you have just perfectly described what I have been experiencing. There are a lot of times when the world looks 'blurry' (but no dbl vision yet). You squint and concentrate to focus on a sign or something - the rest you just adjust. At least I guess that was what I've been doing.

But the other day I was outside - it was a 'crystal clear' day. I was astounded by how sharp and brilliant everything looked - from the print on signs to the leaves on trees - everything was vibrant....and I was feeling particularly perky!

When I made some comment to hubby, he was unimpressed. Said everything looked the same as always. It was just a nice, sunny day.

Guess this is just another something to add to my ever-continuing list of :
