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)

This is why pirates were wearing eye patches, to be able to enter the hull of the ship and see immediately without lighting up a candle. Fire is not a good idea inside a wooden ship filled with black powder.

This is one theory for why pirates wore eyepatches. We haven't found any historical evidence to confirm it. Meanwhile, we have at least a few documented cases of pirates wearing eyepatches for protecting a damaged eye.

I discounted this theory the first time I heard it because it's too cool.

And what's the parrot for?

[โ€“] FleetingTit@feddit.de 3 points 1 year ago (1 children)

Pirates are often associated with tropical waters where parrots live. They probably took them as exotic pets, just like people today.

And: Rule of Cool.
