way to test & objectively compare night vision?

Factual Questions

I may have terrible astigmatism & nearsightedness, but if I were in one of those mutant-heroes movie remakes, my superpower would still be in my eyes: my night vision.

Compared to others (say, when the power goes out) my eyes consistently adjust much faster than anyone else’s and they adjust more, if that makes sense. I can see way better details, navigate confidently while others bump into that thing that’s right there in front of them but I can’t objectively quantify this experience, the way regular vision has 20/20 and your “score” tells you how much better or worse your vision is than the average population.

My dad’s rapidly losing his nighttime sight (and is consequently getting pretty scary behind the wheel after sunset) and between that and my own humblebrag awesome innate power I’d like to boast about … I wanted to know if a standardized test of any kind has been devised?
(By the way: that thing you do in the middle of the night? I can seeeeee youuuuuuuuuuu. :D)

You could do this with a pretty standard psychophysics test. The term you would look for is “scotopic vision.”

I don’t know of any consumer-grade equipment that does this, but a psychology department at your local university probably has stuff.

Amateur astronomers try to spot faint stars, separate (distinguish) close double stars, see faint fuzzy objects, and the like, with larger or smaller telescopes. I bet any local astronomy club would be more than happy to compare their eyes with yours. All these things are numerically quantifiable in various ways.
