quantum physics questions?

I have read that the "Dark adapted eye" can detect single photons. What is the "dark adapted eye"?

This probably means a person who sits in the dark long enough for his eyes to adjust to low light levels can see a single photon. Below is one of many references which say this is, or is likely, true.
