Why do humans have relatively poor night vision?

Only in the last couple hundred years have we really gotten a hold on proper lighting technology.  I realize fire has been around for a long time but a torch is no comparison to good night vision when it comes to hunting or I'm sure a lot of other things.

You're right that a flaming torch wouldn't be very good for hunting. And our own eyes are basically night-blind.    
But why would we hunt at night?    
    
The thing is that we're diurnal. We're usually asleep all night, so there's no real reason to have evolved night vision. but also, large eyes are expensive to make and then they have to be protected throughout your life. So if you're not going to use them, they're more of a liability than anything else.     
      
One more thing to note here is that humans didn't *lose* their night vision, which is what most people assume.   
Actually, none of the apes have very good night vision.    
Not even the monkeys really have very good night vision.    
   
The higher primates have never really been nocturnal creatures and we're just living the *Simiiformes* way of life.
