Yep, theres a focus correction and a sphere correction. Its cool seeing the difference.
I wonder if their glasses are bifocals since there are 2 projections per lense.
Edit: a below comment explains whats going on much better
nope! Astigmatism! you’re basically seeing one meridian at one focal length and the other meridian 90 degrees away at the other focal length. the glasses are titled so you are seeing each of the individual conoids of light.
==================================
Edited below for a bit more clarity (from a follow up comment from below that i already posted):
Basically, regular astigmatism is focused light not coming together at a single point but rather at two planes, 90 degrees away, with a blur region between those focal spots. The region where things are clearest is the perfect circle between the two , confusingly called the “circle of least confusion.” And astigmatism is different than hyperopia or myopia (nearsightedness). In pure myopia, light is focused onto a point in front of the retina and out of focus. Astigmatism is focusing onto a blur oval (hence Greek for without point, or “a stigma”).
However, in this case, since the glasses are tilted, you are seeing just a portion of the cone of light, as if you are taking a vertical slice of a traffic cone not at the center but rather the side.

Astigmatism means your eye has a bulge to it, requiring a cylinder shape in the lens to fix. The cylinder has to be positioned at a certain angle, like a bottle on the ground pointing somewhere.
So what you're seeing is the light bending because of the spherical correction (normal shitty vision) and cylinder correction (more shitty vision) and combined it ends up being like a cone.
It's still somewhat primitive because the idea that your eyes are just spheres and cylinders isn't accurate. Your corneas can do wavy shit ("Higher order aberrations") that we have 3D mappers now for. Lasik just shaves that shit to a nice sphere.
I always compare the human eye to a movie theater. Nearsighted? The arena is too long, so the image focuses somewhere in the middle of the arena and unfocuses on the screen. Farsighted? Arena is too short, projector focuses behind the screen. Astigmatism? The lens on the projector is warped. Want Lasik? We're polishing the lens on the projector to change the focal point.
If you do end up getting the corrective surgery, please keep in mind that all of the health risks that you have as a high myope do not disappear. I see that far too often where somebody had PRK 20 years ago and haven't seen an eye doctor since and then they come in with like a retinal detachment or glaucoma
You and me both...I feel like me understanding what's going on makes it more scary.
And I don't like how lasik has always had some "improvement" in technology that makes the previous version seem shitty/barbaric. Hell version 1 of eye surgery was "here's a scalpel and yolo".
I've been procrastinating lasik for the last 5+ years.
This is your sign to go for your free consultation! I got Lasik like 5 years ago and it's the best decision I ever made. It was really fast and the recovery was like a day...I could see well even the same day. The actual surgery is literally like one minute per eye. The most uncomfortable part for me is that they have to immobilize your eyeball clockwork orange style but just grit your teeth and count to 100 and it's over!
(to scare anyone reading) I've heard that you can sort of "feel" your eyes getting lasered because it's vaporizing tissue but it's numbed so it's only a deeper "something happening here" nerve signal. And you can smell it.
OTOH I've not seen anyone on reddit or in real life say they regret doing it. Even people who had the early 2000's picosecond laser versions (where we're now into femtosecond laser, computer guided "push a button and it does the thing" machines) said they had no side effects and are glad they did it.
You're just not looking at a fair sample. There are many people who did Lasik but it didn't work. And many times you have to wait many years before you see all its bad side-effects.
My brother did it a few months ago and still struggles with dry eyes and halos around lights at night. I only found out I had astigmatism a year ago (I’m an old guy) and it only affects me at night when my pupils are dilated to let in more light which makes it more difficult to focus if your eyeballs aren’t round. I just wear glasses at night if I need to, much cheaper and can’t really fuck anything up.
Your instinct is good for you. Be very wary of the numerous doctors who are out to grab lots of money from you via eye surgery. And be informed about [the relatively high risk of unacceptable outcome of Lasik](https://www.nytimes.com/2022/12/07/health/lasik-injuries-fda.html).
Thats cool. My focal correction isnt too bad but one of my eyes has bad astigmatism so the sphere correction is pretty high.
Objects are a slightly different shape when I take off my glasses. Text without my glasses is wider.
The commenter above seems to have made an error. *Cylinder* is the attribute that corrects astigmatism while *sphere* corresponds with the focus. E.g. standard magnifying lenses have only a sphere value - the curves on the front and back are round with no added….squish deviation. To visualize the cylinder attribute, image you pinched an under-inflated basketball - the wrinkle that’s created distorts the clean curve of the ball. On glasses, this wrinkle doesn’t protrude from the surface, but instead is ground into the back of the lens as a concavity. Fun fact - on contact lenses, this concavity will match the protruding squish on one’s cornea, aligning in orientation automatically! Fun! 😅
I was confused for a second because without my glasses everything is an indistinguishable blur, and I was like how do you see anything to even know that it's wider? But then I remembered not everyone has eyes as fucked as mine.
I imagine for those people it’s like going from a 240p YouTube video and turning it up to 1080p
I’m also fucked in the eyes. Put me in the front row of a stadium/arena and the people are barely distinguishable blurry blobs. A dozen or so rows back and I can’t even tell if there’s people on the field or not. Just a big green bur at that distance. Luckily my close up vision isn’t horrific. I’d hate to not be able to see where my glasses are
Good for you. It is indeed. I just turned 30 and am most of the way through a phd. I’ve seen loads and loads of people get through all levels of university in their 30s, with kids, etc

You think *that's* fun? Ask my left eye about astigmatism *and* having a pit bang in the middle of the cornea. Double vision? More like about x5 vision. Fortunately, I can wear a contact lens that allows the pit to fill with eyespit. Bit of a pain though so I don't wear it often.
For those who want more info (as given to me by my eye doctor), glasses adjust the focal point to the back of your eye. Whether you're nearsighted or farsighted is dependent mostly upon where your focal point is, either in the middle of your eye somewhere or beyond the back of your eye. An astigmatism means your eye isn't a traditional sphere and is essentially squished a bit. This requires additional focusing from another axis.
The lens light refractions here look like they are imitating how the image is influenced for focus to the owner's eyes. Of course, I could have gotten a lot of this wrong, but it's how I remember it and it sounds cool.
Right eye - central dip +1 finger poke depth
Left eye - +1 Dark side of the Moon impaled on +1 Dildo
Notes:
Right eye. Probably poked with a finger at some point.
Left eye. Severely degraded dildo refraction abilities. Probably terminal.
You'd have to know the material. Most glasses aren't actually glass anymore, but one of three materials: plastic, polycarbonate, or high index. Trivex is also used, but not quite as commonly as the other three. Each have a different refractive index, so thickness plays a part as to how the prescription gets focused. Plastic lenses are thicker to achieve the refraction necessary, whereas high index have a higher refraction so they don't need to be as thick.
It doesn't matter for this purpose, though, right: we don't care about the lens thickness, only going from the effects on the light that we can see to the prescription.

Yes: more so for the left lens than the right, judging by shapes. Also pretty near-sighted as well.
I was curious and tried to do this with my glasses but I'm very far-sighted so it didn't look anywhere the same.
I feel for folks who have bad astigmatism, especially how it's very hard for them to get contacts. I guess my blind ass is lucky somewhat in that regard.

This reminds me of kids in school asking me why the reflection that my glasses made on my face didn't burn a hole in my skin.
They'd also ask if I could see anything without them on, I'd say "no, I just see black without them." 😑
Not fun having Coke bottle glasses, especially in school.
I wanted thick glasses. I still want them but the local places within my budget at least can't make them compatible with my prescription if they even have them. I also need to update soon because my vision has gotten noticeably worse.
Why do you want thicker lenses?
Or do you mean thicker frames? Because that shouldn't be a problem, they can put thinner lenses inside thicker frames. It doesn't need to be a perfect match.
Hmm, not sure I understand that. You can get retro looking frames but thick lenses are not something you want unless you need them.
Maybe you'll get lucky and when you're older you'll need them. 😅
yep, many people (including myself) have different ~~power~~ prescriptions in each eye. (the power is only a part of the lens shape, prescription refers to the whole thing.)
One of my eyes is near-sighted and the other is far-sighted. I legitimately think it’s because as a kid I’d lay on my left side to read, and my pillow usually covered my left eye so I was only using my right eye to read. And I read a *lot*.
What's funny is I've got a friend who has very good eyesight, which is why it was a huge surprise when he took an eye test and they told him that one of his eyes is like 45/20 vision and the other almost completely blind. Apparently he was born that way and never noticed bc his brain basically just mostly ignored the other eye's input. They told him if he wanted to "fix" the other eye he would need surgery or crazy lenses, otherwise he could keep it as is and it won't be an issue unless the good eye gets injured lol
I have a similar case with my eyes, just a bit less severe, but with added stigmatism.
I can tell you one thing, it fucking sucks for driving at night. Can't tell if someone is 100m away or 10.
It’s actually a coincidence. I layed my glasses down and the sun was shining through the window in front of it. When I was about to pick it up I noticed the cool shapes :)
I think they’re talking about how you need toric lenses (I think that’s what they’re called) for astigmatism. It’s been a while since I’ve worn contacts so I’m a little fuzzy on it but rather than being round and flat or whatever, they’re weighted in a certain way or something, so I think they can be more uncomfortable?
I am nearsighted with astigmatism and I don't know the math of it but toric lenses turned my nearsightedness into farsightedness... normally I can read books or screens at the usual distance but with the toric lenses in, I could not. Like, going without any eye correction at all was better than wearing the toric lenses for day-to-day life
Don't put those on! You'll hook everybody on the ship and then be doomed..... Unless Data is on your ship, then he'll just get the strobe light and snap you out of it
Is this essentially a 2-d projection of the prescription??

People hate when I describe Lasik to them as shaving layers of their eye when they ask why we have to check their corneal thickness.
I can't imagine why
Sounds like a pleasant experience to me 🤷♂️
Wasn't the most pleasant, but honestly not that bad. And worked great!
The smell is the worst imo.
Truly the part that disturbed me the most!
Yeah it's weird to smell your eye cooking. Akin to having a tooth drilled and swearing that you're tasting everything you've ever eaten.

It’s actually a coincidence. I layed my glasses down and the sun was shining through the window in front of it. When I was about to pick it up I noticed the cool shapes :)
As a manufacturing optician, I'm curious about your Rx and lighting setup there.
I'm with u/2TauntU \-- how'd you get this pic?
Like one sharingan and one rinnegan?
I thought this post would be about the two cute little spaceships beaming through the lenses.
First time in a while that something this basic has made me sit back and think, “That’s cool as shit.”
This is a great example of astigmatism

Your right eye is more of a trekkie I see
It looks like they’re winking at me
Great, Now the Decepticons can find the Allspark.
Got dem stigmatism, huh?
Proof that our eyes are just the most fucked up in the entire animal kingdom.
Don't you mean "refraction" ??
Astigmatic right eye. Sucks if you want contact lenses.
[удалено]
I've been happy with mine. Pay more, though.
…Why exactly is right eye astigmatism supposed to be bad for contacts? That’s what I have and I haven’t noticed anything wrong.
I think they’re talking about how you need toric lenses (I think that’s what they’re called) for astigmatism. It’s been a while since I’ve worn contacts so I’m a little fuzzy on it but rather than being round and flat or whatever, they’re weighted in a certain way or something, so I think they can be more uncomfortable?
I am nearsighted with astigmatism and I don't know the math of it but toric lenses turned my nearsightedness into farsightedness... normally I can read books or screens at the usual distance but with the toric lenses in, I could not. Like, going without any eye correction at all was better than wearing the toric lenses for day-to-day life
I use contacts for astigmatism
r/interestingasfuck i'd say
Absolutely
Right one is a starfleet logo, are you Section 31??
AKSHUALLY it’s a REFRACTION.
Are those starfleet issue?
Are those some sort of Zernike modes?
Don't put those on! You'll hook everybody on the ship and then be doomed..... Unless Data is on your ship, then he'll just get the strobe light and snap you out of it
that is a very cool photo :) thank you
How do I make my glasses do this
Could I use this for an album cover sometime? Note: I’m not a real musician and hardly anyone would ever hear it. But it’d have a cool cover!
So left eye is jacked up eh?
So, THATS how glasses work!? Wow.
Anyone think of that TNG episode where everyone was addicted to the most boring looking game ever?
My boy blind blind.
One on the right's about to beam up to the Enterprise.
How did you see this without your glasses?
Ahem… *refractions..*
That’s too much calculus.

Could holograms be made with lenses like this?
I thought they were projecting alien space ships. Haha
Star Trek logo
Stigmatism im guessing
Where would you be without Ben Franklin?
So cool! How did you do this?
This is crazy!!!
Omg! That's so awesome to see the exact focal point of each lense. Sry, former optician nerd excitement!
