ELI5: Why does looking at a bright light leave image impressions for long periods?

When you look at something really bright ( a bare light bulb for example), why do we see that object when we close our eyes for several minutes? What happens to make this occur?

Very basically, the intense light "burns" an image into your retina. It takes time for it to normalize. What's going on is more about light and chemistry, but it's very simple to say that the light just "burns" an image in your eye and it takes a minute for your eye to recover and see clearly.
