The Short Answer
The photoreceptors (the rods and cones of the eye) contain light sensitive molecules called photopigments. When a light particle hits one of the photopigment molecules, it breaks the molecule apart, and this causes a change in the electrical potential of the photoreceptor cell (which is how you see things). If you are exposed to a very bright light, all of the photopigments in one particular area of the eye have been broken apart, so, until the photopigment molecules are brought back together, you will briefly see a spot in the area where the light was. The spot goes away once enough photopigment molecules have reconstituted themselves.
