What is night shift on iPhone and how it works?

A while ago, I’m asked my friend about what is night shift on iPhone “real function” and how it works? Apparently, he failed to answer my exact question for the second time. Simply because he thought that these feature are not really important. As far as he know that the sole function are only to reduce the light and helping her to read better in low light. As a fellow iPhone user, I feel sorry for him.
