Question

how does the image of flashlight made on our retina ??? or it is something else °°​

Answer 1

Well this is very similar to the effect that you get when you're standing there at a party and someone takes a photo, and you get those spots in front of your eyes from the flashes and you just can't see anything.

It's because of something called photo-bleaching and it happens to the cells in your retina which is the light sensitive bit at the back of your eye. It's populated with cells called rods and cones, and these are full of light sensitive pigments.

Normally you get light as particles called photons coming into your eye; these stimulate the cells by changing this light sensitive pigment, which is called retinal
