I totally want to borrow a projector now.

So, fun experiment.
I wanted to know how my wife's vision was, without glasses, first-hand. So we picked an image, put it up on the projector, and had her look at it with her glasses off. Then, with glasses on, direct me in changing the focus until it was as blurry / distorted as with glasses off. I could then look at the image on the wall and get a good idea of how she sees things without glasses.
Do this. It's p. interesting.
Also +Dawn D / +Damn Finn because his post about glasses reminded me that I wanted to do this.

He sometimes used to miss the bus because not only did he not see the number in time to flag it down, he didn't see the bus in time.
