Why can we see faraway light source (e.g. cars, lamps, stars) clearly when it doesn’t seem to illuminate my position?
The difference is this: For you to see light, the light has to be strong enough to reach your eye and produce a reaction there. For it to illuminate you, it would have to reach you, scatter off you, reach someone else's eye, and produce a reaction there. During the scattering, the light is spread…
The Short Answer
The difference is this: For you to see light, the light has to be strong enough to reach your eye and produce a reaction there. For it to illuminate you, it would have to reach you, scatter off you, reach someone else's eye, and produce a reaction there. During the scattering, the light is spread out more, so it becomes fainter. Let's look at the case of a laser pointer. Point the laser at the wall, and the scattered light is comfortably visible. Point it at your eye, and you're looking at serious eye damage.
