LED headlights are godawful astigmatism or no. Whoever invented them should be made to stare directly into the sun for the rest of time.
Only done poorly, which sadly is most cars, even new. They are aimed too fucking high. Headlights are meant to be aimed down at the damn road. Not up high for far reach. That’s the point of highbeams.
I got projector leds for my car but i properly aimed them, the light has a sharp hard cutoff juuuuust below the windshield on Most sedans at distance to make sure I don’t blind em. If i need more and it’s safe I’ve got my highbeams which turn the road in even the darkest rural to noon.
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.
Of course it was an Audi. They probably have entire departments dedicated to working out how to make their cars even more obnoxious than they already are.
This is going to surprise a few of you. Left with and right without:
With glasses the lights just hurt with darker glasses hard to see, without one see the one on left. All hard choices.
Mine doesn’t look exactly like the image on the left. It’s more of an X pattern.
And that’s WITH glasses or contacts.
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.
Mine are more like crosses which leads me to ask, why are they different?
I’m not an eye doctor - just a guy with astigmatism in both eyes… But my understanding is that astigmatism can happen in multiple ways because it is due to the eye being non-spherical, etc.
Meanwhile, there are limits to what glasses or contacts can do to correct this. Only so many ways a lens can bend light at one time.
I think that’s what leads to people seeing different things, even with glasses on, when it comes to visual distortions like starburst patterns around lights.
Wait, the lens flare effect is because of my astigmatism?
It’s because old movie cameras had astigmatism.
Well, some old movie cameras. That movie-makers decided to be passionate about.
Yep! I found out on reddit, lol.
He didn’t believe me.
That’s just the way things look. ¯\_(ツ)_/¯
You can’t convince me there’s people without the amazing starburst effect, just like you can’t convince me there’s people completely devoid of internal monologue.
there’s an infinity of human experience, and I can’t put myself in everybody’s shoes, but I can at least pretend
Okay, pretend to have astigmatism for so long, it’s just the way the world is to you. Then make about a ⅛ to ¼ -assed effort of making a joke comment saying that you can’t believe other people don’t get so easily blinded by things.
If that’s your vision, y’all need glasses.
I have astigmatism. My glasses correct it. Led lights are fine.
Sorry, but you’re wrong. I’m happy for you everything works but for lots of people they can either have clear eyesight or no issues with light sources in the dark.
And damn, those glasses are expensive!
Eyeglass prescriptions that correct for astigmatism have one “axis” or direction that can be specified. Real astigmatism can be vastly more complex than a single diopter adjustment in one direction. This makes many real astigmatism cases effectively uncorrectable.
Is it unfixable with lenses or only unfix able without lenses custom designed for your eye?
If that makes sense
To correct any possible astigmatism, it would require an infinite sum of series of correction terms at different angles and strengths.
But every glasses prescription I’ve ever gotten in the United States cuts that series off at one term. I’ve never seen nor heard of anyone getting custom lenses with two or more axes. It seems like it should be theoretically possible, but I also know very little about the process of lens grinding.
My understanding is that it’s just a limitation of the physical medium of a glass (or plastic) lens. There’s just only so much it can do - and only so many directions a lens can bend light at the same time before it enters your eye.
I have no complaints, despite the persistent starburst around lights at night. It’s not that big a deal. And I’ve never seen them any other way, after all.
My only other quibble is that my prescription makes everything look a little bit wider than it actually is. Either that, or my astigmatisms (one in each eye, and different from each other too!) make everything look more narrow than it really is? I’ve never really been sure….
I have astigmatism and have always had Starbursts despite the correct prescription. I’ve even had doctors double check to make sure I have the correct prescription after my complaints. So, either I’ve had several different doctors fucking with me for the last 30 some years, or humans are weird and not one size fits all for every situation
Odd! I have no idea what that means.
Had a young friend checking out my new red-dot sight.
“Why’s it look like a star?”
“I have bad news…”
Irons gang rise up!
Etched reticules are also fine, and holographics are barbed wire but at least it stays contained.
Do they make glasses that just fix astigmatism? I have great vision and don’t need glasses for sight. But I do have gnarly astigmatism.
They do. Get ready to feel drunk for a couple days if you get them.
Yes, and contacts too (for mild astigmatism)
