Give me a present and it better be a good one.

I have another gift for you: reversing goggles, which will allow you to see things from the correct perspective (upside-down).



Unfortunately the brain, being the wonderful machine that is is, will reverse the image back after a while, even when you're wearing these goggles, giving this product limited effectiveness. Planned obsolescence is a -censored- thing, but it does make the world go round.

There was a TV science programme about vision a couple of decades ago. They used these glasses to show how vision was primarily centred, post processing, in the brain. The scientist had to use these goggles for a month before his brain sorted the image out. Of course when he took them off his brain didn't immediately switch back. It took two weeks to be seeing normally again. Well being a glutton for punishment he repeatedly put them back on and off again to the point where his brain adapted virtually instantaneously.

I've always wanted to do that since I watched tv upside down as a kid.
