The only other product analogy that comes to mind is "thicker = better" for hiking socks. When they got too thick, they applied too much pressure to the heal and also provided additional moment distance making it far easier to roll an ankle.

It doesn't help at all with head on traffic, but glare via my side mirrors has been reduced greatly since I implemented this.
It should be illegal, but there you are.
There is the possibility (as said by an apologetic driver) that it sometimes may be a badly functioning automation ("Too high? Oh but it's automatic").
I have blue eyes, it hurts to drive at night.
- glare for older people might be due to deposits in their lens, which can be corrected by cataract surgery. The deposits make oncoming headlights like a dirty windshield at sunset. (disability glare)
- glare for people with good vision is all the light focused at the same point on your retina and is sort of painful. (discomfort glare)

some cars have matrix/adaptive headlights now:

I always have blue blockers (yellow and also dark orange lenses) in my car and wearing them totally prevents pain and fatigue for my eyes.
I drive a 40 year old vehicle and a friend created an aftermarket adjustable headlight frame allowing it to move from all-in-one rectangular headlight/high beam sealed units to modern LED bulbs and then an accessory of choice on the inner spaces left over. I chose a classic-looking LED that does regular, high beam, DRL, and amber turn signal all in one and then put off-road fog lights on the inner spaces. But I would not leave the house after night with the vehicle until I adjusted them to DOT spec. Because they are so much brighter and sharped-edged than factory, I can see that they don’t go above oncoming windshields and are aligned properly horizontally.
The excellent guide that I used to align my lights:

Surprisingly the Cybertruck also has this layout.

What really pisses me off? LED bulbs only available in 6000k or higher. I had to import some Osram H4 bulbs from the netherlands because they are a warmer factory 3000K temperature. We really need regulation on glare, because right now it's the wild west.
I drive a normal height hatchback. I live in Texas. The /vast/ majority of vehicles on the road are trucks and SUVs, and many of them have aftermarket lift kits which further exacerbates the problem. The main problem is vehicle height and improperly aimed headlights. There's no real enforcement or regulation for headlight aiming, and worse we have no effective vehicle height restrictions. Not only do these insecure little men blind you at night, their cattle guard/reinforced bumper mounted to the frame will decapitate you if they hit you because of the bumper height difference from the 6+ inch Chinese lift kit they added to their truck to stroke their ego and allow them to "bully" drivers on the road by intentionally tailgating and driving aggressively in their oversized vehicle.
The problem is epidemic in America, and it's a problem of both regulation and culture. As long as the typical American driver is somebody who enters the road ignorant of basic driving dynamics, with a selfish attitude, inattentively barreling down the road in their massive fuck-off symbol of insecurity, we are not going to fix this.
I will say, while there's now more overly bright headlights of varying degrees of blinding, it's better then when every truck started buying HID headlights and putting them in normal headlight housings. Felt like there was a period of time where headlights were either the normal tone, or a super bright light hitting you from all directions
Seems like a classic Tragedy of the Commons situation / use case for regulation....
