Yep! I found out on reddit, lol.

It's because old movie cameras had astigmatism.

Well, some old movie cameras. That movie-makers decided to be passionate about.

He didn't believe me.

there's an infinity of human experience, and I can't put myself in everybody's shoes, but I can at least pretend

Mine are more like crosses which leads me to ask, why are they different?

Ooooh look at Mr. Fancy pants over there with his special astigmatism. Meanwhile we're all stuck with the regular astigmatism.

Joking aside, that's pretty interesting.

they are shining directly into your eyes.

That would be illegal in most of Europe and will fail an inspection, resulting in a fine.

Id rather blame it on beam shape which in your cars are symmetrical and designed to shine straight onto opposing drivers face. Here I immediately see at night that incoming traffic is a car with LEDs because they blind me less - you must come here to believe me I guess, but check what beam shape is by law mandated in the EU. And it is much much easier to control the beam shape exactly like you want it with multi-LED headlights.

Same as the comment you replied to.

Illegal?! How about cars with Xenon lights, they were also illegal? It’s mandatory in EU for cars with xenon lights to have automatic leveling, spray nozzles, limited power output and more controlled beam shape than standard bulbs.

I think you're thinking about adaptive headlights (turns into the turn). I've had imported self-leveling headlights since 2008 (Mini)

Aiming the LEDs is only a partial solution, as soon as you got a slight incline you're beaming straight into oncomers' eyes

The car designers specifically dampen their headlight output in the exact spot where regulators measure their light.

But there's also the issue that they have way too much blue light. Blue light still damages eyes even though it's only UV adjacent and not UV.

do your headlights adjust when you are on a slope? because if not, then you're just blinding people at the top of the hill.

I mean, it's certainly better if they're dipped properly, but each individual LED is still far too bright.

A scooter with a ring of single LEDs on it drove past me once - I guess they were some sort of cosmetic thing - and they were still dazzlingly bright in full daylight.

Is it unfixable with lenses or only unfix able without lenses custom designed for your eye?

If that makes sense

They do. Get ready to feel drunk for a couple days if you get them.

Yes, and contacts too (for mild astigmatism)

It depends on your specific flavor of astigmatism. You'd have to get your eyeballs thoroughly checked out by a fancy eyeball doctor to know if yours can be corrected with glasses (or contacts) or not. Some can be, some can't be, some can be partially corrected. At least that's how the fancy eyeball doctors explained it to me.
