Our eyes see by detecting photons and they are pretty darn good at it. Does not take a ton of photons to see ( detect) light.

Car lights. When you are looking directly at them, your getting ALL the photons hitting your eyes. blinding up close, less far away but at a long distance your sill getting some

If your sitting in the car. The photons are not going straight to your eye. The photons are going out and bouncing back to you. Many are absorbed by material before coming back to your eyes. ( like the light is white, BUT you only see the colours of the stuff you can see. ). This means there are less photons hitting your eyes, Vis a Vis less light.
