While trying to read this, I find this better description of the original 2 photon vision stuff; fun!

Thank you! The original link is nearly incomprehensible: "Imagine that instead of viewing an image through a lens, you look through a kaleidoscope that focuses invisible light to obtain a new range of colors." WTF?
Yeah I think an LLM was heavily involved in the "writing" of this article.
Yeah it's like they were trying to stretch out the article length by repeating the same few points over and over in different words.
That was my initial reaction, as well.
Your link isn't working for me, do you have a doi?
The title made me think of the minimum number of photons detectable by human vision. Apparently, we can detect single photons:
I wonder if that's why Angela Collier posted this recently:
This is a well known phenomenon. It accounts for example in the flash perceived when someone inadvertently looks at an infrared class 5 laser and is blinded
In standard laser classification, there are only four classes. Class 4 includes IR laser welding systems...
You’re right, I meant class 4
Maybe they're only blind briefly?
