you are literally seeing an aspect of reality you couldn't see before. this isn't something you can really explain to someone who doesn't see it. the best you can do is try to give them instructions for doing weird stuff that might restore their depth perception natively

you also don't have to understand anything about the physics or neuroscience of depth perception to have it. you don't have to know what parallax is or have the idea that the brain is capable of inferring depth from comparing the views from your left vs. right eye

the foundational thing is to have it at all. there are things you can do with depth perception that others will struggle with, like accurately hitting animals with projectiles from a distance, and you can demonstrate this skill to others, at least

some of the first few accidental pioneers might become wild-eyed prophets, spreading the Gospel of Depth wherever they can, with varying levels of success

eventually one hopes the WALL-E humans successfully spread the Gospel of Depth everywhere, whereupon it might gradually, over generations, fade back into the background of human experience

if your depth perception is functioning perfectly you don't need to pay attention to it; if everyone's depth perception is functioning perfectly nobody needs to talk about it. sometimes attention is for things that need repair

nevertheless this was an important and pivotal moment in their history; one hopes they'll keep records of how they learned that they lost something and learned how to get it back, to help future generations keep it

This is a really cool thread, I'm obsessed with different ways of seeing. For eg have you heard of the Moken? "Moken children are able to make their pupils smaller and change their lens shape. Seals and dolphins have a similar adaptation?"

I can’t control my pupil size, but I can focus and defocus at will. Is that rare?

I can too but I remember talking about it once with people and some couldn't - I don't think it's super rare, but def not universal

my eyes are actually defocused by default if i'm tired or stressed out 😅
