I'm currently limited to mobile, so I don't have he link. Yesterday I got recommended a green laser at freezing temp YouTube video which was interesting. Basically at low temps green lasers are no longer visible because they shift to strong uv light, this includes Christmas decoration lasers which people put in front of their houses. So you think it's off, but it may be cooking your eyes.
So I guess that if they used some shady lasers at the party, it's entirely possible.
I think I also burned my eyes a bit while tinkering with LEDs, I had a pain in them and since then see bad at night. I avoid watching into LEDs at any cost since then.
"Having now had a chance to take a look at the likely culprit, assuming a repetition of the previous incident, all I can say is You Completely Irresponsible Fucks. I am having flashbacks to yelling at Naomi Wu for irresponsible deployment of germicidal UV designs in 2020."
The footage ive seen had a few green lasers scanning. UV causes cornia damage, but not the headaches. IR lasers cause headaches, strange pains that the body doesnt understand and get interpreted as headaches.
If this was only UV, most anyone wearing glasses should have been protected as most modern glasses have substantial UV protection. IR protection is more rare in eyewear, although rather common in automotive glass.
So when I roll down a car window and feel the radiant heat of the sun more intensely than when the window is up, is that difference primarily due to the glass filtering UV or IR?
Much automotive glass filters (reflects) IR, and also absorbs UV. Each UV ray is "higher energy" but the sun pumps out vastly more IR than UV. You cannot immediately feel the UV on your skin, not until it gives you a sunburn. You are feeling the IR that was previously blocked by the automotive glass.
Interestingly, glass on military vehicles generally does not filter IR. You need IR if you ever want to use nightvision equipment.
