The danger with that is not seeing a deer that's about to bolt in front of you on the road. And in an urban environment, it's easy to not see a pedestrian who is wearing dark clothes.

The issue is contrast not total light levels. https://www.polarization.com/water/water.html

So, it can actually be much easier to see someone with dark clothing when I have sunglasses on.
