So here it is - a bad representation of what my ocular migraines look like (graphic from http://www.eyeguys.net/ocularmigraine.html).
OK, so I went to the eye dr. today (he was super nice). Since my mom had eye problems early on I decided not to mess around and go see a real eye doctor. He checked out my eyes with the new-fangled machinery and my eyes themselves are very healthy. Great! But then as I was explaining these strange arcs of diamond-like vision distortion that I get from time to time and he brought out this card that had some drawings on it. They looked kindof like this picture. And I immediately noticed that the picture was exactly what I was trying to explain. I was glad that I wasn't crazy. It's nice to know that there is a real name for these things - although I guess they are kindof rare. But the visit couldn't have gone any better.
