Question: Why when you see a bright thing, like a flash, and then you turn around, you still have that flash in your eyes, like you still see a light or a dark spot?

This is caused by you retina. When the light hits the retina with a high brightness it takes time for the photocells in the eye to readjust to light that is not as bright. Thast why in a few minutes the spots disappear. its just your eyes readjusting
I get that, too. Weird. Search it on GOOGLE and see what you can find.
the light is still bouncing around in your eye
Because it has blinded you for a second then it leaves that black spot on your eye that you can see for at least half an hour.
hope it helped :)
Your eyes have an 8 second "memory". Another way of showing it is to stare at something green for a few minutes then look at a white piece of paper and you'll see a red image.
I believe that it happens when your eyes get "oversaturated" with light of a particular color. The dark spot should go away eventually (hopefully.)
The image has been temporarily "stamped" on your retina.
A bright light depletes the chemicals in visual cells, making them (temporarily) less efficient.
In strong light this can be very useful.
But if a small area of the retina is strongly exposed, and then the eye views a more evenly illuminated scene, the cells that have been exposed respond more weakly, leaving a darker area for a white light, or a dark inverse colour if the source was coloured.
At night the reverse occurs and eyes gradually build up their sensitivity as the cells stock up their chemicals: "Dark adapting".
