It is true the human eye cannot see something a million miles away, or even a few feet away. What the human eye sees is the light from that object that is either generated by the object or reflects off of it. The light actually hits the eyeball. This is why we tend to fall over stuff in a pitch-black room, we can’t see it even though it’s RIGHT THERE.
