Guess I don’t need to do that because my vision already streaks! Seriously though, I haven’t met anyone else that experiences what I do. At night, sometimes when looking around lights in the dark like a streetlight, moving my eyes will trigger a delayed streak 1 second later, like a lightning bug shooting across my vision in the same path the streetlight just took. It’s inconsistent.

Could be a physical defect in the top layer of the eye, or cataracts/something in the “jelly.” You move your eye, but certain parts don’t necessarily move with it and any scrape, scratch, or object in the eye will “float” across your vision like that.

I’m familiar with looking at lights. Usually, what you’re describing is more of a blind spot that develops where the light lingered. I’m not looking at the light directly, either. It’s usually noticed when looking at a street normally with a streetlight above.
Instead, this is like a bright streak that flashes across my sight. Not a lingering streak, not a burn, not a blindspot. Just like a repeat of the streak. Due to the flick nature of humans changing eye targets, the streak isn’t even perceived at first when I move my eyes. They snap to the next target. But the repeat streak has some motion to it, though very fast. I considered mechanical means of triggering receptors, but it matches the placement and direction of the source. If I turn my head and do the same exact eye movement, the repeat streak moves as well.
I spend a lot of time in the dark. I’ve tried, but I can’t find a pattern. I initially thought it was a rhodopsin artifact (the chemical that dopes your receptors for dark adaptation over ~20 minutes without blue/UV), but I’ve had it happen immediately when going into darkness. Maybe my home isn’t as bright as I think it is? But still, it’s not a permanent feature and only works for a few minutes once I notice it.
