Why can't we decrease our eye's FPS to get better night vision? (feddit.de)

My phone is normally worse for color gradients and contrasts than my eyes. Also, normally it has worse nightvision.

But when decreasing the shutter speed, for example in OpenCamera, I get crazy night pics.

I see that when its dark my FPS goes down, I see less frames automatically and totally cant control that.

Could this mechanism be altered, to have even less FPS but more photons in the soup to get brighter sight?

Yes, trying to hack my eyes here. "Getting used to darkness" is normally the pupils getting wider, there are quite some interesting plants to do that but I havent heard of anything altering the brains image processing.

Edit

I learned:

in Nightsight we use the rod cells, which take longer to send a signal. That way they capture more photons, but the "FPS" is lower
you can trick your iris naturally to stay open, like the Pirates did (some plants like nightshades also do this, applied locally)

I'm like you. Bright lights - including daylight without really dark sunglasses - are painful but in low light conditions I can operate far better than the average person.

I don't know if anyone had this in my family before me, but I strongly suspect that my kids have inherited it from me. They are quite young, but we'll see.

You get the odd reaction when everyone complains it's too dark to do something and you reply it's just fine?

More often than you'd think.

When I lived alone while studying, I usually kept only a tiny kitchen worklight on. My friends were always baffled by this when they came to visit.

Once my co-worker asked to borrow my favourite sunglasses. When she put them on, she was still for a moment and then went "MY DEAR GOD, HOW CAN YOU SEE ANYTHING WITH THESE ON?"

The only sunglasses that make sunny days outside enjoyable for me. And yes, they are very dark.

I learned how to handle sun light but I can relate with that so well.
