Low light vision.
I was always very sensitive to bright lights and sincerely fear I'll go blind at my last years but I can see at higher definition under low light conditions.
My vision stops processing color and I get higher definition of contrast. I've walked through dark areas with no difficulty, where others simply said they could not see a thing.
Maybe everyone already knows this but you can generally see better in your peripheral vision in low light.
Almost all of your color vision / cones are concentrated in a tiny central area of your retina.
The grey scale / rods are dispersed around that.
In some ways I think night vision is a kind of skill that some people might be better at than others, even if the mechanics of their eyes aren't special.
Based on what I've read about senses, I think most of human sensory variance is born in the brain and is trainable to be much more sensitive than we'd generally expect possible given our comparatively weak hardware. Some of us have the supertaster gene, but no one comes out of the womb a sommelier.
It should. Seeing in low light is a very useful thing. And we could dispense some of the light polution we create.
Both my kids got this ability from me. We all wear sunglasses all the tome pretty much. Im approaching 50 now so my eyes aren't as good as they used tp be, but we all have 20/20 or better still. We are always asking people to turn off their flashlights so we can see.
I got the same thing. In the army I realized that I was the only one in my platoon who was able to read maps clearly at night without lights. And I never needed a flashlight to navigate the woods in the dark.
My night vision started to wane clearly in my early thirties, but being closer to 50 now I can still see a lot better at night than my friends whenever we go camping. Still, I bought my first headlamp a few months ago ;)
I'm not very sensitive to bright lights. But I can also see better in low-light conditions than anyone I know. Not sure how that works.
