I'm experiencing some weird eyesight thing just now.

It started about a half an hour ago at the center of my field of vision as a blurry dot. Then it expanded and made the center of my vision absolutely useless.
The blurriness was combined with some weird distortions that made things sort of 'cubist' in that region.
I couldn't use my computer or read at all. Thank goodness I wasn't driving at the time.
I kept blinking my eyes trying to clear it up- to no avail.

After about 15 minutes the spot had expanded a great deal and lo and behold the center began to clear. Now I was looking through some weird donut shaped Picasso lens and it was slowly growing.

Now it's been a good half hour and it's mostly cleared up now with some leftover spots hanging around the edges.

Anyone have any idea what's going on?
