Question - "glittery" pattern in front of eye(s) Update #11

[Catty1]

I was at a gathering tonight. Drank some soda water, had a couple of carrot sticks. Seriously.

Just when I went to leave, I noticed a funny pattern in front of my left eye. You know how when you look at something bright for a bit too long, you can "see" it for a minute or two afterwards?

This thing started looking like an award seal - the round ones with the pointy serrated edges. Except this was clear in the middle and the 'points' were clear, but kind of fluttery as some bits of colour came and went.

I was driving home and it was dark. Little by little, the pattern widened til it was at the way top and left of my field of vision. SEEMS to be gone now. But it was totally weird.

I am way overdue for an eye checkup, so I will book that tomorrow.

Have you ever had this happen to you? Did you find out what it was?

thanks.

ETA: I didn't think I could find anything on this...but "ocular migraine" fit pretty well. A headache may not even happen.
