I’m taking about the bright dots which appear that seem to zip around in your sight for five seconds or so, usually after one of the above…..?

I touched a laptop adapter on the metal part that connects to the outlet (after taking it out) one time and I had this for like 5 seconds but much more pronounced. Weird stuff.

I call those sparkles. Always wondered what they were, I get them if I cough too hard. Glad to know I’m not the only one since my doctor didn’t understand me lol

A lot of people mentioned blood pressure, which is the cause of what you’re talking about. However, there’s another neat thing you can do that is similar – some time, when the sky is very clear, look at it for a while and let your eyes unfocus. You’ll start to see dots wandering around your vision, even though you can’t really focus on them. What you’re actually seeing there are the white blood cells in your eyes! When you look at “blank” space, like the sky, your eyes don’t really know what to focus on, so they focus on the thing changing the most, which are the constantly moving blood cells in your own eye.

Doesn’t answer your question (since others have already done that), but it’s still neat and it demonstrates that our sense of sight is very odd sometimes.
