When I was very young, around six or seven, I'd have a dream in which perspective was out of whack. Close things were small, distant things were large, and even one finger would be larger than its neighbor. Very strange, but eventually it went away.

Fast forward to about 1985 and my eyesight was corrected to a close to 20/20 as possible. And again comes The Dream....

When I was six or seven I started to wear glasses, which corrected my vision as much as was considered possible (I had uncorrected amblyopia and one eye is far stronger than the other -- in fact, I'm both nearsighted and farsighted). When the ophthmalogist asked my in the mid-80s if I'd like to try for near 20/20 correction (and he explained the hazards to me), well, it was back to corrected vision and back to The Dream!

As far as I can tell, in both cases my brain was opening up new pathways for seeing AND for coping with what I was seeing. The brain is a wonderful thing indeed.
