As someone with regular ocular migraines, opening this on mobile made my anxiety shoot straight up thinking I'm having another.
I'm only slightly trying to play a 'trigger warning' card here, it's completely unnecessary and looks awful, just as my vision does when this happens. It made me check a few other sites back and forth to make sure I wasn't seeing things. Normally when I see this, I figure I'm gonna be going through the motions for the next hour.
Sounds like mine are milder they only last around 5-10mins and I just get the central ring - looks like I stared at a donut shaped lightbulb for too long, and almost never associate with a headache (but sometimes with a hard to describe wooziness).
