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)

Would suck to have night vision during the day haha!

Thanks for the info! So a NVG collects the light and then shoots it out again? Or also increases the capture surface?

Night vision goggles usually are very sensitive to visible light yeah. Im not sure on exactly how the optics work but some modern ones are set up more like vr. Some are also sensitive to near infra red, and some see entirely in infra red. The latter are thermal imaging. The longer the wavelength you go (the more red) the more difficult it is to create sensors that receive a good image. You can imagine that putting a thermal eye in a warm blooded animal might be a bit difficult because the eye itself will be emitting light that overpowers the scene.
