No I’ve seen what you describe. What I see when I’m having one is most often a shimmering electric zigzag. Sometimes it take different shapes and the colors vary. Its always at the edge of my vision and moves when I move my eye. Its better to close your eyes when they are happening. At least for me. I have had them in both eyes at once and its really freaky since normally I only get them in one eye at a time. They don’t merge well and the combined blind spots have rendered me almost complete unable to navigate. I’ve pulled over while driving more than once and waited it out.
Comment on They'd just appear out of nowhere
LyD@lemmy.ca 2 days agoI don’t get ocular migraines so I have never seen something like this. I can see subtle multicolour flashes if I close my eyes and do things like looking around quickly or apply pressure to my eyes. Would you describe what you see before an ocular migraine like that, but 1000x more intense?

It is called a scintillating scotoma or ocular migraine. Scintillating is accurate; this clear crescent shows up in your vision and It is rippling with rainbow fringes. It starts off as a point somewhere in your vision, slowly expanding into a visible crescent that continues to expand. After about half an hour the crescent expands beyond your field of vision (FOV). For me it is paired with a loopy slightly lightheaded feeling that goes away with a whoosh once it leaves my FOV.
They are often triggered by bright light and may be correlated with migraines. I’ve had three of these happen but never had a migraine headache afaik.
