Why do I see black spots after looking at a bright light?

What happens if you stare at a light bulb too long?

If the light is not quite so bright, chronic exposure over days to weeks can cause permanent damage. This is thought to be due to what is called photo-oxidative damage; the light reacts with the retina to produce molecules that are very reactive and cause damage to surrounding molecules.

What happens when you stare at an image?

Staring at an image in a book for 60 seconds or so before turning to stare at a blank, light-colored wall can produce this type of afterimage.
