Better vision at night, or during cloudy or Dusty conditions. Every truck driver should have them. Every search&rescue or police officer should have them although I suspect for firefighters it might not help. I wouldn't at all be surprised if Mr money mustache can make a frugality case to wearing ir contact lenses instead of having lights on at night. Instead of splashing people with UV paint and using black lights, just party in the dark. As people age, one of the common complaints is the degradation of low light vision. This will help some. At least some hunters I know have night vision goggles for going after wild hogs. They could just wear the contacts...
