Weird issue with my eye

Just happened. Makes me think of retinal fatigue, when you see the afterimage of something that’s not there anymore. Except that I wasn’t staring at anything for a long period of time; not even my phone.
As I type this, a spinning block of colors blocks the view of parts of the screen. If I move my eye to look directly at the spot, it moves. Always to the right. Lol I’m often afraid of retinal damage. I was fine till a minute ago.

I wonder what caused this. I stepped outside to turn off the swamp cooler connection, then went back inside to get some food from the freezer. Nothing weird. Now something is wrong with my eye. I would think maybe I got battery acid dust in it from the car earlier, but it would have happened hours ago so I doubt that’s what the issue is. (If there are a bunch of mistakes in my writing right now, it’s because the words are blocked by the weird spinning colors)
