Ian, thank you so much for posting that. That has taught me a thing or two! I was asked the other night why the side of the eye is more sensitive to light. My answer was, "because it is". Now I'll be able to give a slightly more scientific reason ;)

Yes, it's all upside down. The cornea and lens in your eye effectively form a single (uncoated - pah!) optical element, and this projects an upside-down image onto the retina.

There was an experiment once where somebody spent a week wearing special goggles that turned everything upside down. For the first few days they spent a lot of time falling over, walking into things and stabbing themselves with forks. Then, after a few days experience with this new world, they totally got used to it. Of course, when they took the goggles off after a week they had to re-adjust all over again!

So what all this shows is that your brain soon adjusts to the input it gets. For all of us, our brains since birth have only ever seen the world upside-down - so they've long ago got used to it.
