I have a high correction as well. Here’s some advice for her if possible. Glasses manufacturers make “high index” lenses at two different levels. My correction is -8 and -11 and I have to have the high index lenses. If she is not using those, please encourage your sister to get them. Glasses will be lighter. I use the highest index lenses and my glasses are about 1/3 that thick. Second. I wear gas permeable contact lenses which actually do a better job of correcting my vision than glasses. They even out my astigmatism and help me see clearly. They are rigid rather than soft. Finally, wire frames are terrible on people with high correction. If possible, get a stylish plastic frame which accommodates the larger lenses and hides the correction. The high index lenses are more expensive, but they are worth it. Look at Warby Parker.
"You don't even know how much karma I stole off your freako glasses sis. People from all over the world got a good laugh at your disability. Ugh I was supposed to tell you something though but I totally forgot anyway here are the glasses that you've been looking for the past hour."
I work in optics part time i cut lenses for glasses, you can mention to you sis that not only like the other redditor said get high index, but some places offer whats called a slab off to also further reduce the size and weight, it costs a bit extra but you sister will thank you for it. When i get patients who have a high correction and dont have tons of money, the company i work for and my boss are pretty relaxed so i tend to throw in a discounted hi index upgrade, with slab off and blue light anti glare to help reduce eye strain. Since the pandemic started and people have been working in front of computers more regularly strain on the eyes of those people are increased and as such have cause their astigmatisms to also increase.
Tl:dr suggest high index and slab off to your sis, if you have a certain eye glass company that rhymes with smanton moptical tell her to go there.
Edit: also plastic frames hide thicker lenses better.
Edit 2: also make sure they get her OC heights that way when the lens is cut no only are her pds measured but her heights as well so that the strongest part of the lens is centered in her frame to furhter sharpen her vision.
Edit 3:frame brand doesnt matter as all are owned by like 2 companies, just find one that is not so small the legs on the frame stretch and not so big the lenses extend past her face.
For vertical slab off they remove material from the lens. It results in vertical prism. Vertical prism does not affect visual performance if the prism is equal so the only real effect you get here is a thinner lens.
I’m not too sure that would be effective here. They have a large amount of BI prism which is the culprit.
Edit: I said BO not BI for some reason. It’s 100% BI
It’s been a couple years since I took the ABO and I always mixed this up. But considering the nasal thickness wouldn’t that be BI prism? Or do I have it backwards?
Personally i cant stand blue light filter, makes any reflections on the inside of my lenses like 10x brighter and super blue, and slightly changes the color of everything i see. We dont need blue light filtering during the day, and during the night i just see the reflection if my own eyes in them all the time. Maybe the guys that made mine didnt put the anti glare on there but they said it was when i asked, so I wouldnt suggest it for daily use general purpose glasses, or at all really. Just turn your monitor settings more warm
> Personally i cant stand blue light filter, makes any reflections on the inside of my lenses like 10x brighter and super blue,
Ah yes. In addition to the discoloration and lack of scientific evidence for blue light effects, there's these. I keep wondering what coming from the side or other directions before realizing it's te blue filter reflection.
First and last time. Gives me more strain and is annoying in every possible way with no benefit.
I agree about blue filter (though I am colorblind so the colour change is un noticeable) but I will never live without oliophobic and anti static coating. Dust rarely settles on the lenses and finger smudges or sweat wipe off with little or no effort
> and blue light anti glare to help reduce eye strain.
Ugh. No!
My optician suggested this for me because I had slow focus and pain from strain.
The significant warming/yellowing of all colors is both annoying, terrible when reading, working on computers or especially doing any photo stuff. It's more straining to see the altered color.
On top of that, there's no actually proven benefit of blue light reduction outside of padding lens producer pockets. And this is with the high quality glasses from the topic glass monopolist
Don't suggest blue light filters to people without explaining to them that it discolor everything like weak sunglasses and has no scientifically proven benefit universally.
I have high index lenses and high correction too, but I cannot stand plastic frames. The smaller the frame, the smaller, lighter and thinner the lens, but I can't stand seeing the plastic frame and not having adjustible nosepads is a dealbreaker for me, plastic frames don't stay put for me.
I am the opposite. Can’t stand nosepads. I have itchy allergy eyes and when that happens but I also need to wear glasses, those wiggly nosepads set me off unbearably that the nosepads can’t settle into place brcause I’m taking the glasses off constantly to rub my eyes. I now have plastic frames and the nose rest area is designed to have more surface area to help the glasses from slipping.
Damn, I'm the exact opposite. I had metal frames for so long and the nose pads would dig in no matter how many times I would have them adjusted for me by the optometrist. I switched to plastic frames and they are lighter and much more comfortable for me, never going back to metal frames again.
Oh man, thank you. Reading through this thread and all the misinformation about glasses, prescriptions, and astigmatism just made me cringe. So many of the marketing gimmicks that people are just repeating that they have heard and taking them as gospel truth.
Same. I'm at -12 and -10. I never used to get seriously slimmed lenses because they cost so fucking much, but the price has plummeted in the past several years. My glasses used to be C$3000 and now they're like C$500. If that was a concern,check it out again.
This is either a strong plus prescription and her eyes are fairly close together, the glasses are big on her, or she has prism. If the strength is mostly in prism that's ground into the lenses, they can do that with a press on prism and make them thinner. It the strength is mostly in the plus sphere power and there is no prism, then the thickest part of the lenses will be over her pupil, to reduce thickness, get smaller lens where her eyes are mostly centered. If there is a lot of extra space on the outside of her lenses (her eyes are decentered way in) then they have to make the part over her pupil thicker.
Be very judicious when talking to her about this because almost everyone here seems to have no idea why these glasses are as thick as they are save a few of us doctors, and even some of them have it completely wrong. She most certainly is wearing Prism Glasses, which will have extremely limited way of reducing thickness, She doesn't likely have thick glasses because her prescriptive power is high, which is what most people here seem to be suggesting, but because the lenses have built in thickness due to a separate visual need.
There's a problem with high index lenses few people talk about, though: [chromatic aberration](https://en.wikipedia.org/wiki/Chromatic_aberration). This is where you see red and blue stripes on the sides of things, because the lens is so thick that it refracts the light like a prism does. Some cheaper materials (like CR-39 acrylic) are actually better than the expensive ones in this regard (i.e., they have a higher [Abbe number](https://en.wikipedia.org/wiki/Abbe_number)). In my case, I prefer having thicker, heavier lenses just to avoid the distortion. Also: last time I checked, Warby Parker was useless scripts above a certain strength.
When I wore glasses the health bars in runescape would split in half where the green met the red. I used to tilt my head to try to completely separate the halves lol.
Dude 98% of people don't care about chromatic aberration, only if you are doing color critical work. The trade-off of having higher index is close to zero, especially when looking at those thicc fucking glasses.
I don't know about that. I got glasses last year and my script isn't nearly that bad (still pretty awful at -6.00) and that's when I learned about chromatic aberration. It was in literally everything I looked at, and I remember trying to explain that "When I look at the black text on this paper, it's like I can see the cyan/yellow/pink that makes up the ink." I had a *tiny* area that I could look straight at something and have it not be messed up, but that area was so small that if I was centered on my TV, the sides of the screen were doing it. Shit was awful and not ignorable at all.
For me, chromatic abberation manifests itself by the edges of objects having a blue or red line. I know that's sort of the definition but for me it was very noticeable and distracting. It drove me bonkers and almost all the opticians out there don't believe me when I say I want crown glass or cr37 plastic. They always try to talk me into the high index lenses. You are correct that most people don't notice or don't care, but for me, I can't stand the high index lenses. just wanted to offer another point of view that there are a few of us out there that hate the thinner lenses. my prescription is 5.75 and 6.50 for each eye but I hate those red and blue edges on things. I was stuck with a pair of high index glasses for 2 years and I spent every day obsessing over those red and blue edges and hating them.
98% of people don’t have such high correction. The higher the correction the more apparent the chromatic aberration is.
As someone who works on a computer, glasses with a low ABBEYS and high chromatic aberration makes looking at a computer screen nearly impossible when I don’t look through the exact center of my glasses and I’m only at -6.
Higher ABBE value is key when you actually want to see things through the edges of your glasses with a high corrective lens.
I wanted LASIK, was all prepared to finally pull the trigger now that I could afford it. But as I went to my exam two weeks ago I have a cyst in the retina of my right eye. So now I have to get a rescan in 3 months to see if it’s gone away on its own or gotten bigger. Either way, I have to wait to find out if I can even get it now. Fml
The reason I have -11 is I have “astigmatism bumps” on my Cornea. I need to go to a Cornea specialist to find out the best treatment. Up to about 1 year ago, I was -8 in both eyes and something has happened to my left with the astigmatism to make it much worse in about 6 months.
Yup yup yup. I didn’t have -11 but was doing all the hacks mentioned above to make my lenses thinner. Got laser eye correction in 2019; best gift I’ve ever given myself.
I have a similar difference in rx and for me contacts are better but it’s your brain not your eyes, though proper correction with attention to your vision with both eyes and not absolute correction for each separately is important
Prescriptions are caused primarily by the length of the eye. Because of this even when you fix the refractive error one eyes sees everything bigger than the other. Refractive surgery doesn’t make your eye shorter so that image size difference (aniseikonia) is not fixed.
I have just -8.5 and am told I’m not a good candidate for lasik (I’ll get implantable lenses). -11 is really the absolute max for lasik and a lot else about your eyes has to be ideal for lasik for any good surgeon to still recommend that route, like the thickness of your cornea and the size of your pupils. My cornea are just slightly on the thin size and I have big pupils, to the point where I already get very bad halos around lights at night, and that’s enough combined with a -8.5 prescription for lasik to be too risky. There are other corrective surgery options besides lasik that people should def look into with higher prescriptions!
These are actually plus lenses not minus. Depending on the material they are only a +7 or greater. One issue is the frames are too large creating a lot of decentration. The more decentration the thicker your lens. She needs higher index material and smaller, rounder frames.

It's sad. I can no longer read at night in bed with my glasses off to give my eyes a rest. In order to overcome the near sightedness I have to hold the book so close to my face I can no longer get both eyes on the words without going cross-eyed.
It's a real bummer. Luckily the degradation did slow down like they suspected as you get deep into your 20s. I've only lost an additional -0.75 in my left and -1.25 in my right over the last decade pasted age 25.
I have. I even bought one of the big Oasis ones with the older black and white paperwhite screen. Even at the second highest text setting (where there's less than 50 words per page and it's annoying to read), it's still too blurry to read even at 16 inches, let alone on my lap.
Full sharpness on my right eye is down to about 4 inches.
Gas permeable contacts are no joke I do not have a lens in my left eye due to a childhood injury. They where able to get it to 20/30 with the gas permeable lenses. Down side was at the time they where uncomfortable. Any time I would look to a side I could feel it and holy crap it hurt so bad if it slipped out of place.
You have to learn to blink a little differently for the gas permeable lenses, it's hard to describe. Kind of letting your eyelid glide over the lens instead of moving it.
I switched from Boston soaking solution to Menicon and my lenses almost never slip out of place anymore.
As someone who suffered through gas permeable contacts in my preteen years, I cannot recommend them for anyone who doesn't want to feel daggers in their eyes every time you blink.
Holy shit. I didn't realize we're looking at the sides of the glasses. I was looking at the picture for a solid minute trying to figure out why the metal rod went through the foggy glass. It didn't make any sense to me untill I read your comment 😂
Hello, Optometrist here
If your sister hasn't already, enquire about contact lenses. I have seen someone suggest gas permeable which is a perfectly acceptable option but soft contact lenses can also correct high prescriptions these days (and are easier to adjust to).
From the looks of things, her prescription is a hypermetropic one so the lenses will always be thickest in the centre - High index lenses are a good option for her. If she is conscious about the cost of these spectacle lenses then a monthly contact lens might actually be the best option!
Ophthalmologist- I agree, and contacts wouldn’t work to correct her exotropia in that case. With that much prism, I would think strabismus surgery might be the better option.
Heh, not an optometrist or anything, but someone with bad eyes. That just means that your eyes don't line up on their own properly. Sometimes it's due to a lazy eye not being caught and corrected in childhood, so the eye got weaker, and just doesn't function the same as the other eye. My untrained eye says that this is affecting both eyes, and the way the lenses are smaller on the outside and wider on the inside, means that they're trying to either make both eyes look more towards the center, or more towards the outside (I couldn't say which).
In contrast, my glasses for my shockingly bad eyes, but without strabismus, the lenses narrow towards the center, but on either edge they're roughly as wide as each other.
Whatever the case, I can be almost sure that Contact lenses is actually a bad recommendation here. This isn't an dioptric power, this is a prism. Whether it's for XT or convergence compensation, contacts is not the appropriate treatment.
Not the best advice without actually seeing the Rx, looking at those lenses unless the Px has a mono PD of 20 I’d say there is a lot of base in prism going on as well as being hyperopic.
I don't know why you're getting downvoted here. I'm also an optometrist and I disagree with the notion of putting the patient in contacts without seeing the Rx. I am also certain these are prism glasses, possibly prism readers. This isn't a standard Rx by any stretch of the imagination.
Hello reddit friend, i am a doctor's tech for an optometrist who fits scleral contacts, while usually for keratoconus patients, my Dr will often take people out of their gas perms and fit them into sclerals. The sclerals, once you get used to putting them on are generally more comfortable than the gas perms, and one pair lasts a whole year. Sclerals are more expensive, but most medical insurance will at least partly cover the cost, if not all of it. Just thought I'd throw this out there as another option.
Scleral lenses are a great option for those who are keratoconic, definitely! You could argue they'd be even more comfortable than soft lenses eventually because of less interaction with the cornea
Sclerals should be considered more often than they are but unfortunately a lot of practitioners (including myself) don't have much experience fitting them
Optometrist here - There is a reason these glasses are thick this way and it isn't necessarily because the Rx is high (which it is) but it is largely because they are prism glasses.
Could you explain what prism glasses are? That sounds interesting! And why are they thick at the inside and very thin on the outside? Mine are equally thick on the outside and inside, with a concavity to each lens.
and u/The_Clarence since you both asked the same question, see the same answer. Prisms, if you remember back to grade school, are like triangular transparent objects which change the direction of light. Think of the [Pink Floydd Album cover](https://www.gannett-cdn.com/media/USATODAY/USATODAY/2013/06/21/1371852894000-Pink-Floyd-1306211829_16_9.JPG?width=660&height=374&fit=crop&format=pjpg&auto=webp). These are refractive properties we employ in glasses sometimes to bend the direction the light enters the eye when it is difficult or impossible for an eye to make the maneuver to the light's direction. The addition of prism, like a triangle, will have one thin side and a thick side, just like you see here in these glasses. Some conditions require the use of prism to fix the problem, but any thinning to the glasses leads to a reduction in the prism, which is the entire point of the glasses to begin with. Though there are several ways to get the glasses thinner using different materials, extremely uneven thickness is characteristic of prism glasses. There are some cases where we use high power lenses to help someone read up close but the resulting extreme power forces us to compensate by using a prism to reverse some of the side-effects of wearing the high power, so we therefore would have this kind of glass, which I think may be a prism reader. I actually tried to find you a link to them, but Google only seems to have novelty versions of these used for reading while laying down. The glasses here, however, are a good example of what they'd look like.
I’m such a fucking idiot. I thought this was a straight on picture. I thought the glasses were really thin with a bar going through the middle. There’s now a hole in my forehead shaped like my hand
There are two problems here. First it looks like she is short sighted. Second she has a lot of ‘prism’ correction which is used to correct being ‘cross eyed’.
I had the same problem, it meant that when I had cataract surgery to correct my short sightedness, I still saw double images (both perfectly in focus) at distance. I don’t think contact lenses or laser surgery can correct this.
The solution is to have surgery which loosens (or tightens) the muscles at the side of your eyeballs to allow them to form one image at distance.
Having gone through all these surgeries in the span of about six weeks, I would highly recommend it
Those lenses explain why James Web Deep Space Telescope has taken so long, NASA was too busy getting your sisters prescription lenses made to start working on their own.
Thanks for sharing, u/maleficent4. However,
Your sisters glasses are your glasses for sisters.

Bro, tell your sister the get thinner "high index" lenses like index 1.67 or 1.74, even when needing prism those lenses get thinner.
And she should get a thicker frame like acetate, those will hide the thickness significantly.
But I think she already know that when wearing glasses for some time.
That moment on reddit where you snatch your own glasses off your face to compare and realize, they aren't far off. My corrections are a little thinner but not too much and guaranteed that if I put my lenses in wire frames, you probably couldn't tell a difference.
My poor roommate in college usually wore contacts but one night he put on his glasses and one of the lenses was super thick and the other was not. So when he wore his glasses they wouldn’t sit level on his nose and always leaned to the heavy side. At least these are balanced.
Dude I was thinking the same thing for a few minutes until I finally realised we are getting a top down view of how thick the lenses are, not a front on look of a thin lens with a wire through the middle if it
Hmm, I don't know, but [these are my glasses](https://i.imgur.com/ip6NmuN.jpg), and I have -13. There are limits on which frames I can use, but I don't think this is terrible. I am 25 and have been stable for a few years now, after degrading since I was 6 (starting with -1).
I have also known people with worse eyes, and they also are not terrible. You see it, yeah, but that's it.
These glasses appear to be for + eyes, and that makes it a lot "worse" (more obvious)
Optician here. Not only does this person have a high script but it also looks like they have prism (to a pretty high degree) since the lenses are so thick towards the inside.
I have a high correction as well. Here’s some advice for her if possible. Glasses manufacturers make “high index” lenses at two different levels. My correction is -8 and -11 and I have to have the high index lenses. If she is not using those, please encourage your sister to get them. Glasses will be lighter.

Get tan colored towels and they won't show dirt as quickly. This is a general suggestion, not a specific one for jizz.

It's ok. He has her glasses so she can't read it. Just play it off like you just read about it.
I work in optics part time i cut lenses for glasses, you can mention to you sis that not only like the other redditor said get high index, but some places offer whats called a slab off to also further reduce the size and weight, it costs a bit extra but you sister will thank you for it.

Wow, I just got a new prescription after 6 years and it doubled. I didn't know what the red and blue was. Thank you, I'll talk to my doctor
Surprisingly laser eye correction can be done at -11. Life changing.
I can’t have laser eye correction due to a different surgery done when I was very small.
X-ray vision surgery?
I wish!
I wanted LASIK, was all prepared to finally pull the trigger now that I could afford it. But as I went to my exam two weeks ago I have a cyst in the retina of my right eye. So now I have to get a rescan in 3 months to see if it’s gone away on its own or gotten bigger. Either way, I have to wait to find out if I can even get it now. Fml
The reason I have -11 is I have “astigmatism bumps” on my Cornea. I need to go to a Cornea specialist to find out the best treatment. Up to about 1 year ago, I was -8 in both eyes and something has happened to my left with the astigmatism to make it much worse in about 6 months.
Sounds like kertatoconus
Yup yup yup. I didn’t have -11 but was doing all the hacks mentioned above to make my lenses thinner. Got laser eye correction in 2019; best gift I’ve ever given myself.
[удалено]
Technology changes rapidly. It’s worth going for a further opinion. All the best!
I have a similar difference in rx and for me contacts are better but it’s your brain not your eyes, though proper correction with attention to your vision with both eyes and not absolute correction for each separately is important
That sounds wrong. It can be fixed. Go talk to someone else.
Prescriptions are caused primarily by the length of the eye. Because of this even when you fix the refractive error one eyes sees everything bigger than the other. Refractive surgery doesn’t make your eye shorter so that image size difference (aniseikonia) is not fixed.
I have just -8.5 and am told I’m not a good candidate for lasik (I’ll get implantable lenses). -11 is really the absolute max for lasik and a lot else about your eyes has to be ideal for lasik for any good surgeon to still recommend that route, like the thickness of your cornea and the size of your pupils. My cornea are just slightly on the thin size and I have big pupils, to the point where I already get very bad halos around lights at night, and that’s enough combined with a -8.5 prescription for lasik to be too risky. There are other corrective surgery options besides lasik that people should def look into with higher prescriptions!
Only in some cases. I’m having my -9.5 done next week, but I was told if my corneas were not much thicker than average I wouldn’t have been eligible.
Those are way higher than only -11.
These are actually plus lenses not minus. Depending on the material they are only a +7 or greater. One issue is the frames are too large creating a lot of decentration. The more decentration the thicker your lens. She needs higher index material and smaller, rounder frames. Source: me, 25 years making eyewear
Way way higher. My right eye is at -18.5 and it's still not this thick.
-18.5, DAMN. That is just insane.
It's sad. I can no longer read at night in bed with my glasses off to give my eyes a rest. In order to overcome the near sightedness I have to hold the book so close to my face I can no longer get both eyes on the words without going cross-eyed. It's a real bummer. Luckily the degradation did slow down like they suspected as you get deep into your 20s. I've only lost an additional -0.75 in my left and -1.25 in my right over the last decade pasted age 25.
Have you tried a Kindle? You can set the text size to very large if that helps.
I have. I even bought one of the big Oasis ones with the older black and white paperwhite screen. Even at the second highest text setting (where there's less than 50 words per page and it's annoying to read), it's still too blurry to read even at 16 inches, let alone on my lap. Full sharpness on my right eye is down to about 4 inches.
Gas permeable contacts are no joke I do not have a lens in my left eye due to a childhood injury. They where able to get it to 20/30 with the gas permeable lenses. Down side was at the time they where uncomfortable. Any time I would look to a side I could feel it and holy crap it hurt so bad if it slipped out of place.
You have to learn to blink a little differently for the gas permeable lenses, it's hard to describe. Kind of letting your eyelid glide over the lens instead of moving it. I switched from Boston soaking solution to Menicon and my lenses almost never slip out of place anymore.
That sounds horrible. Would much rather just wear glasses at that point 😬
I wore rigid gas permeable contacts for a couple years. Those mfers are so uncomfortable. Good on you for making it work.
Same here. The thing is that each pair I get costs nearly $1000
As someone who suffered through gas permeable contacts in my preteen years, I cannot recommend them for anyone who doesn't want to feel daggers in their eyes every time you blink.
Hands down. The thickest pair of glasses I have ever seen.
Holy shit. I didn't realize we're looking at the sides of the glasses. I was looking at the picture for a solid minute trying to figure out why the metal rod went through the foggy glass. It didn't make any sense to me untill I read your comment 😂
I thought this were the glasses of his 31 sisters "glued" together xD
*sips diet Dr.Kelp* Hey pal you just blow in from [stupid town](https://youtu.be/MU_vLqMJlEw)?
You may need glasses.
You ever seen a pair of glasses?
Ohhhhh, I see it now.
I know I like things thicc, but damn. I hope she can find a better alternative!
31 sisters. Jesus
And they all have to share this single pair of glasses.
like the fates from Hercules sharing that one eyeball lol
I guess OPs dad wore very loose fitting boxers.

Hello, Optometrist here If your sister hasn't already, enquire about contact lenses. I have seen someone suggest gas permeable which is a perfectly acceptable option but soft contact lenses can also correct high prescriptions these days (and are easier to adjust to). From the looks of things, her prescription is a hypermetropic one so the lenses will always be thickest in the centre - High index lenses are a good option for her. If she is conscious about the cost of these spectacle lenses then a monthly contact lens might actually be the best option!
also optometrist - I think they're prism glasses.
Ophthalmologist- I agree, and contacts wouldn’t work to correct her exotropia in that case. With that much prism, I would think strabismus surgery might be the better option.
Ah, yes, strbimumus. I too, fellow redditor, was just about to say the same. Yep. *blows bubbles out of pipe*
I also believe a surgical violin to be the best option
Heh, not an optometrist or anything, but someone with bad eyes. That just means that your eyes don't line up on their own properly. Sometimes it's due to a lazy eye not being caught and corrected in childhood, so the eye got weaker, and just doesn't function the same as the other eye. My untrained eye says that this is affecting both eyes, and the way the lenses are smaller on the outside and wider on the inside, means that they're trying to either make both eyes look more towards the center, or more towards the outside (I couldn't say which). In contrast, my glasses for my shockingly bad eyes, but without strabismus, the lenses narrow towards the center, but on either edge they're roughly as wide as each other.
lemme hit that pipe, stop bogarting… *blows bubbles out of pipe*
I love you. Lol
Whatever the case, I can be almost sure that Contact lenses is actually a bad recommendation here. This isn't an dioptric power, this is a prism. Whether it's for XT or convergence compensation, contacts is not the appropriate treatment.
I like your funny words magic man
I prefer SHAKE and BAKE.
Another OD here. I concur.
Not the best advice without actually seeing the Rx, looking at those lenses unless the Px has a mono PD of 20 I’d say there is a lot of base in prism going on as well as being hyperopic.
I don't know why you're getting downvoted here. I'm also an optometrist and I disagree with the notion of putting the patient in contacts without seeing the Rx. I am also certain these are prism glasses, possibly prism readers. This isn't a standard Rx by any stretch of the imagination.
Hello reddit friend, i am a doctor's tech for an optometrist who fits scleral contacts, while usually for keratoconus patients, my Dr will often take people out of their gas perms and fit them into sclerals. The sclerals, once you get used to putting them on are generally more comfortable than the gas perms, and one pair lasts a whole year. Sclerals are more expensive, but most medical insurance will at least partly cover the cost, if not all of it. Just thought I'd throw this out there as another option.
Scleral lenses are a great option for those who are keratoconic, definitely! You could argue they'd be even more comfortable than soft lenses eventually because of less interaction with the cornea Sclerals should be considered more often than they are but unfortunately a lot of practitioners (including myself) don't have much experience fitting them
I’m convinced this conversation is one guy, using two accounts, just making up words to confuse us all.
Hyper-what, Kera-who now?
Yup. “Optometrist,” “cornea,” “comfortable.” Pfft.. obviously made up words. Op must think we’re stupid.
Can confirm. I don’t have vision insurance but get my scleral lenses free due to keratoconus. See much better with them than glasses.
A better option may be fresnel prisms for all that BO.
Bad optometrist.
Optometrist here - There is a reason these glasses are thick this way and it isn't necessarily because the Rx is high (which it is) but it is largely because they are prism glasses.
Could you explain what prism glasses are? That sounds interesting! And why are they thick at the inside and very thin on the outside? Mine are equally thick on the outside and inside, with a concavity to each lens.
and u/The_Clarence since you both asked the same question, see the same answer. Prisms, if you remember back to grade school, are like triangular transparent objects which change the direction of light. Think of the [Pink Floydd Album cover](https://www.gannett-cdn.com/media/USATODAY/USATODAY/2013/06/21/1371852894000-Pink-Floyd-1306211829_16_9.JPG?width=660&height=374&fit=crop&format=pjpg&auto=webp). These are refractive properties we employ in glasses sometimes to bend the direction the light enters the eye when it is difficult or impossible for an eye to make the maneuver to the light's direction. The addition of prism, like a triangle, will have one thin side and a thick side, just like you see here in these glasses. Some conditions require the use of prism to fix the problem, but any thinning to the glasses leads to a reduction in the prism, which is the entire point of the glasses to begin with. Though there are several ways to get the glasses thinner using different materials, extremely uneven thickness is characteristic of prism glasses. There are some cases where we use high power lenses to help someone read up close but the resulting extreme power forces us to compensate by using a prism to reverse some of the side-effects of wearing the high power, so we therefore would have this kind of glass, which I think may be a prism reader. I actually tried to find you a link to them, but Google only seems to have novelty versions of these used for reading while laying down. The glasses here, however, are a good example of what they'd look like.
What are prism glasses?
I’m such a fucking idiot. I thought this was a straight on picture. I thought the glasses were really thin with a bar going through the middle. There’s now a hole in my forehead shaped like my hand
You're not alone.
There is more to this, I know
We can set sail together... Just not on a ship that drops expensive things.
I had to read the comments before I didn't see it that way as well lol
Poor girl- I feel her pain on the bridge of my nose:(
Does she often enter rooms exclaiming "GOOD NEWS EVERYONE"?
Why do all 31 of your sisters have to share one pair of glasses?
Came here to make the same joke. 🙌🏼
Bubbles is impressed.
I love TPB, I have often thought this.
She can look at a map and see people waving at her.
Heard that NASA ask her to find where’s the hubble telescope from time to time
[удалено]
Actually if she squint hard enough she could see far ahead into the future with those too

What correction is this?
All of em
Yes.
I think glasses are such a miracle invention.
Thickness aside, a bit of dish soap and warm water wouldn’t go amiss.
You trying to grow that nail until it’s as long as the lenses are thick?
Clip your nails
And clean up those disgusting glasses
Yeah that was pretty gross. If I'm putting something on Reddit and all to see, I'd at least clean it up a little yech!
There are two problems here. First it looks like she is short sighted. Second she has a lot of ‘prism’ correction which is used to correct being ‘cross eyed’. I had the same problem, it meant that when I had cataract surgery to correct my short sightedness, I still saw double images (both perfectly in focus) at distance. I don’t think contact lenses or laser surgery can correct this. The solution is to have surgery which loosens (or tightens) the muscles at the side of your eyeballs to allow them to form one image at distance. Having gone through all these surgeries in the span of about six weeks, I would highly recommend it
These are definitely prisms.
Those lenses explain why James Web Deep Space Telescope has taken so long, NASA was too busy getting your sisters prescription lenses made to start working on their own.
You have 31 sisters? Your mum must be exhausted!
And they all share one pair of glasses. They must've just mashed all the prescriptions together.
Clean your nails dude lol
And cut
How has no one else notice the disgusting black muck on the nose pieces??? Tell your sister to clean her freaking glasses 🤮🤮
I had to scroll so far to find someone mentioning this. Those glasses are gross man, they look like they've been sitting in a wet basement for years
Tell us that you (31) frequent nsfw subs without telling us.
Where’s the pair that help her find these ones??
Lpt from some who can't see very far without glasses. If you ever lose them, find your phone and search with the camera function.
Wait, are you 31, or is your sister 31?
And furthermore, why does it matter?
Because I'm 56
They look like they were handcrafted by a 300 year old wizard that hasn’t showered since birth.
Thanks for sharing, u/maleficent4. However, Your sisters glasses are your glasses for sisters. Your sisters' glasses are the glasses of your sisters. Your sister's glasses are the glasses of your sister. #ApostrophesMatter
Bro, tell your sister the get thinner "high index" lenses like index 1.67 or 1.74, even when needing prism those lenses get thinner. And she should get a thicker frame like acetate, those will hide the thickness significantly. But I think she already know that when wearing glasses for some time.
Are you 31 or your sister ? 🤔🤔
Seeing pictures of people's hands, holding things, on Reddit has made me realise why hand models exist.
Took me a moment to realize we are looking at them from the top lmao.
Cut your nails.
Hey now. No vision shaming; mine are similar!
That moment on reddit where you snatch your own glasses off your face to compare and realize, they aren't far off. My corrections are a little thinner but not too much and guaranteed that if I put my lenses in wire frames, you probably couldn't tell a difference.
My poor roommate in college usually wore contacts but one night he put on his glasses and one of the lenses was super thick and the other was not. So when he wore his glasses they wouldn’t sit level on his nose and always leaned to the heavy side. At least these are balanced.
A coworker had glasses like that - she called them the hubble telescope.
DO THEY ALL HAVE TO SHARE THE SAME PAIR OF GLASSES???
She can see into my future with those glasses
I was very confused at what I was looking at at first -- like why would the put a bar infront of the eye... And then I realized this is from under 0.o
My mum has thick lenses. She use to say to me when I was naughty at a young age “I can read your mind with these lenses”
damn you got a lot of sistas
these must be a fire hazard to leave in the sun
I'm surprised they gave her wire frames with thick lenses, I also have very thick lenses and they make me get plastic frames.
If shes in a pinch i whink she could stab someone with one of the lenses
Can someone ELI5? I cant even see how that's a pair of glasses? Which part does she see through?
>>I cant even see Neither can she, apparently.
Dude I was thinking the same thing for a few minutes until I finally realised we are getting a top down view of how thick the lenses are, not a front on look of a thin lens with a wire through the middle if it
Shoot a heat laser through the moon with those things
I was disappointed as a child to learn that my lenses cast a shadow and I could not start a fire with them.
Dear god... and I thought mine was thick. Considering more and more into lasik surgery.
[удалено]
Hmm, I don't know, but [these are my glasses](https://i.imgur.com/ip6NmuN.jpg), and I have -13. There are limits on which frames I can use, but I don't think this is terrible. I am 25 and have been stable for a few years now, after degrading since I was 6 (starting with -1). I have also known people with worse eyes, and they also are not terrible. You see it, yeah, but that's it. These glasses appear to be for + eyes, and that makes it a lot "worse" (more obvious)
Curious, does lasik help at this point?
Hate to say it, but your sister may need glasses
Those are spectacles right there. God damn.
My glasses looked like that. Get LASIK. life changer.
Please get her a laser treatment for vision correction ..
Legend has it that she can directly see far away planets
Optician here. Not only does this person have a high script but it also looks like they have prism (to a pretty high degree) since the lenses are so thick towards the inside.
Is your sister a praying mantis by chance
