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.

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...

Maybe they're only blind briefly?
