Blue LEDs. We had red and green since the '60s, but blue took until the '90s to figure out and the guy who did so got a Nobel prize for it because that finally meant we could use them for white lights and full-color displays.
Well not him, I guess, just the designers of all those devices that have a blue laser like led in it shining in my eyes at 4 AM in the morning. Fuck all those digital clocks, TVs, etc.
No, that would be the assholes who lift their trucks, or perhaps your optometrist. Properly aimed LEDs don’t blind for shit. They blind me less than oldschool projectorless halogens even.
“properly aimed” LEDs blind the shit out of me on a daily basis, because roads are not flat and smooth and always at the same elevation as the surroundings

so that’s the guy I can blame for blinding LED vehicle headlights?
No, blame the guys who put them in the blinding LED headlights.

It’s also opened the door to some very interesting synthetic chemistry applications that use blue light, it’s changed the field of photochemistry

I remember when the only color laser pointer was red. Now you have all the colors of the rainbow.
And damn powerful. So powerful you get almost every time wayyy more than allowed/advertised.
