In reply to goosebump:
This is pretty spooky - I got new glasses on Saturday, and could have just written your OP. I don't NEED them, I'm comfortably better than the driving sight test, I've got a slight astigmatism, and they're my first glasses. Add to that, I only have really any correction on the right eye, and I find things are slightly sharper now (and markedly improved when I close my left eye), but WOW are things looking weird! It's ike walking round with in some kind of overdone 3D movie! Added to that, things with the right eye have a slight barrell distortion now, which means things look shart, but tilted about 20 degrees! On saturday I was watching crystal clear water running uphill. It has made walking pretty interesting, and one leg appeared to be but things seem to be evening themselves out a bit. I've also found computer screens to be smaller on the right side, and bigger on the left, but sharp throughout. It does seem to be getting better though, and I've certainly noticed my eyes changing (ironically, my vision seems to be marginally worse now without than it was last week, though it sorts itself out within a couple of minutes of no glasses), so hopefully the weird drunken feeling will come to an end soon - it's been a bit like waking with a fisheye lens over one eye! I'm going to stick at it with a couple of weeks and see if I get on with them, otherwise, I might start investigating things like contacts.
