But it's not an eyelid twitch and that's what everyone usually means when they say eye twitch. It's my eye itself. Like, I can be staring at something, and then I look at something else, and for a split second I see two of them and then the one associated with my right eye meanders back to focus with my left eye. It happens too when my left eye is covered. So I guess it tends to happen more when I look from thing to thing but also when I'm staring. It's disorienting, but not enough to be more than somewhat distracting.

I can't find anything similar on medical logs and the like. Maybe I'm searching for the wrong thing. "Double vision" does describe it but not well in my opinion because it's not consistent. But I guess I should try.
