The photoreceptor cells in your retina get temporarily overloaded by the very bright light, so they continue to send a signal down your optic nerve to your brain for a couple of seconds after you've closed your eyes (i.e. after the stimulus has been cut off). It takes a little time for the cells to 'reset' to normal, so the afterimage persists.

That is a quick reaction of the human eye, when suddenly exposed to a power full light it closes to protect the inside of the eyes. When you take the photo at the same time the picture will appear as you are closed eyes.

we see things because our eyes collect light rays and focus them on the retina at the back of the eye. The retina contains photoreceptors that when excitated by light send an action potential to the brain. Bright light strongly excites specific receptors and the chemical takes a while to diffuse.

Your eyes work in a simular way to cameras, normally anything you see is temporaliy imprinted on the sensors at the back of your eyes.
Because the bright lights penertrate these sensors more fiercly, it takes the sensors longer to disperse the light rays which means the picture stays there longer.

You should never look directly at the sun as it damages your eyes. Just thought I'd point that one out before people run off to try it.

the light gets reflected of the back of your eye and when you blink it gets reflected of your eyelids.Only flashes and direct sunlight etc. gets reflected, because it is more and brighter light.
But don't look into the sun - it's dangerous

the sun is in your eyes so then it looks like you are blinking

Because the light was so intense it takes your eyes a few seconds to adjust. As simple as that.

I think the technical term is image retention. Not that I'm an expert or anything

because it is burned into your retinas
