I’ve had them occasionally for years and had no idea what they were until I acquired a neurologist as a client. She immediately diagnosed it as an ocular migraine. I call it the “best kind of migraine”. My mom used to get regular migraines, and they were incapacitating - she’d have to lie in a dark room for an hour until they passed.
I don’t generally mind mine, and as I don’t drive they are never a danger. I’ll usually get one while I’m working on the computer. I’ve never figured out what triggers one, although I did have one triggered a month ago.
I was shooting a concert. I was in the middle of the balcony of the venue with my big camera with the 20x lens, my medium camera with the 12x lens, another 10x camera, the wide shot camera and a monitor to show my a quad-split of 4 other cameras. So there were a bunch of monitors that I’m looking at, in the dark.
This women sees me shooting, decides this is the perfect shooting spot and sets up camp five feet from me. This would be fine if she had the faintest idea who to shoot, and had read the fucking manual for her camera. We’re 40 feet from the stage and she proceeds to shoot one picture every 10 seconds…
…with the flash on!
I tried to talk to her, and she got obnoxious. She would not move, and spent the entire 90 minute show doing the same thing in the same place.
There’s a flash going off five feet from me. I wound up having an ocular migraine, and was no longer able to see out of the center of my vision, so I’m trying to aim my cameras with the my peripheral vision.
I think I should be nominated for a Nobel Peace Prize for not throwing her off the balcony.
