It can also be light sensitivity.

I have, apparently, insanely good dark vision compared to my wife. If there is slight moonlight, or light pollution on a cloudy night I can make out pretty much everything in our house just with ambient light from outside while she can barely see what's 4 to 5 feet away. When I go to the eye doctor they don't have to dilate my pupils because they get so large in the dark they don't have to.

It's possible your pupils get much larger and take in more light than your wife's. She might see with the same clarity, 20/20, but not get enough light to see dim things. I wouldn't say that makes her eyesight "bad" if that's the case. She might be better equipped to deal with bright scenes instead.
