Does anyone else share a seriously acute night vision, or...?

Yup; me, too. And, I'm excellent at finding lost objects.

I can see amazingly well in the dark, although none of my siblings seem to share this ability and stumble all around and into things. I don't know what you mean by particles in the air unless you're speaking of pollutants or pollen, which I see quite well when they are there.

sounds similar to me. but I can only see dust particles when they are in a sunbeam shining into a dark room. sometimes at night I am almost blinded by oncoming cars and streetlights and feel that if all the lights where out I could see much better

uhhh...they're called floaters and they are not in the sky but in the fluids of the eyes. Everyone has them to some degree just some more than others.

my eyes are very sensitive to light and that hurts my vision at night especially with headlights shining in my eyes. Maybe the things you see has something to do with your blood pressure. if they are like lightning bugs thats what it is

You may be experiencing floaters - have you seen an ophthalmologist? Here is a site that briefly describes floaters. Check it out and see if it matches what you are experiencing.

well humans are used to seeing in the day, so it will always be easier to see in the light.

i have the same problem
