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.

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?
