My friend best described her vision difficulties like this:
"Ok so imagine you are reading a book. First, squint a bit until the words get a bit fuzzy. Next, cross your eyes and shake your head back and forth. That makes it hard to focus on the story a bit, right? Good. Now, hold a piece of wax paper in front of your face. Finally, just go ahead and shut off all the lights in the room."
It was after a long day and she was pretty frustrated, but it always stuck with me as a perfectly hyperbolic way of walking someone through the idea. It really breaks down the expectations and gives them a few examples of the difficulties that arise at different stages between "20/20" and "entirely blind". The thought experiment should still work if you personalize it as well. Just substitute any of the middle examples as you see fit, and have the final part be more tailored to your own vision levels or peraonal experience.
