Thank you! I have an astigmatism with a cyl of -5.75, one of the worst my optometrist said he's ever seen, so I've been looking for a video with a better visual of what astigmatism is to better understand 😅
Great video and explanation! I'm an optician educator in NC. You're awesome! I'll be linking this video in my lessons. This will definitely help my students. Thank you for what you do!
Mine was never corrected in my myopia prescription and I always wondered why I had this double text Vision even just after getting my new prescription glasses, I had always thought that maybe the optician didn't give me the correct prescription
Want to talk about weird eyes, I am nearsighted in one eye and farsighted in the other. And, both eyes have mixed astigmatisms. The prescription I wear is the one where my two eyes work best together, but if I cover either eye and just use one eye things are out of focus. Incredibly, because of how the brain works, I actually have 20/20 vision (and depth perception) when my two eyes work together. The weirdest part is I never knew this about my eyes until I needed reading glasses. Until then, my far eye saw far and my near eye saw near so I never knew I had a problem.
Thanks Mr Antonio . Qestion : in with the rule astigmatism , why do we correct it with a plus lens axis 90. form your explanation, the curvature x 90 is steeper and it focuses the light before the retian ....
I have astigmatism in both eyes, corrected by +1.50 cyl in both eyes, 165 and 10 degrees. Sph plano on both. Reading + 2,75 I have recently had varifocal/ progressive glasses, but wondered do they give me any extra distance from the top as it varies to the bottom?
I'm 17 and i diagnosed with astigmatism -3.25 with no spherical power in one right eye and -3 cyl with -0.75 spherical power in left eye . My visual acuity without glasses is 6/18 in right and 6/24 in left . I see blur from left but not with left . I have problem in seeing far distances. I got glasses but after two days i see lines from bulb
@@AntonioTheOptom Hmm. So then with purely astigmatism and no myopia, you still can see more clearly close up? If you make the letters on the computer screen small at close distance, do you then see double edges even at that close distance?
If you have ONLY astigmatism and not myopia or hyperopia, is the distortion in your vision the same at all distances? Or do things closer up look less distorted than things farther away due to the pure astigmatism? Edit - he answers this in a comment below
Great video! If the astigmatism level btwn two eyes is more than .50, is it possible that a person has a hard time with eyeglasses prescribed with the proper Rx? I found it quite difficult to get accustomed to a higher -1 cylinder in one eye and a -.25 in the other when viewing though both eyes, even after a time of using new glasses.
Yeah the cyl difference can be a challenge. I have about -0.75 difference in astigmatism between the two eyes and it was hard for me to adjust to glasses initially too
My both eyes have a cylindrical number, 1 and .75 and I even wear glasses, but I don't know why objects still appear blurry all the time, especially shiny objects, please help me doc.
Nice explanation sir🤗 I am also studying optometry third year.Thank you very much🤝 this video is useful for me 😮toricylindrical that topic is difficult. Now make astigmatism easier to understand😍🙂
I have binoculoar myopic astigmatism ...i got my glasses...i have my glasses for 4 days now...my problem ia rhat my astigmatiam vision is stil there..blury far vision...and a little doubled vision...i don't know what to do...Or is thia normal in ajustment period?
But what is the root cause of the the increasing curvature astigmatism? How to prevent or maybe reverse it? Please reply. And also what is the root cause of Hyperopia?
Is it normal to have eye strain looking up close with toric contact lenses? My eyes are relaxed looking at the distance but I struggle with reading books etc.
Hi Antonio, I am 29 and I have cylindrical -3.5 both eyes with different eyes. I am diagnosed with blue dot cataracts which are in developmental stage. Does the cataract surgery remove my power and axis both? I want to do away with the axis because the specs won’t suit unless Pupiliary distance is correctly measured. Waiting for your response. Thanks
What about astigmatism with presbyopia? My vision is perfect ...sph PL - OU, -0.50 cyl OU, 177 OD/ 33 OS, add +2.00 OU. But i don’t understand the +2.00 as everything is clear at all ranges, just letters and numbers are ghosted/layered. Why the add???
I think I can answer this one. My son's eye doctor thought he might have had keratoconus a while back, and mentioned how important it is that he doesn't rub his eyes too hard. If you have a stigmatism, you're more tempted to rub your eyes and risking damage to your cornea.
@@syzygy4365 Shocking. I have keratoconus, and now I suspect I got it as a result of rubbing my eyes. When I heard that this is a possibility, I hoped that my source was wrong. The more doctors I hear agreeing that rubbing one's eyes can be dangerous, the more likely this to really be the case. I can''t believe I gave keratoconus to myself...
I used my lense for the right eye on the left one and the left one on the right for 8 days😂 My right eye perscrip is: +1.75 Cyl : -1.25 Axe: 180 Left eye: +1.5 Cyl: -0.75 Axe 180 My question is, did I damage my eyes? It was a mistake and I felt it because I was seeing lines in one eye because the lense wasnt sitting good on my eye😳 Thank you for your answer in advance
Sir, when i look straight my vision is perfect but when i see nearer things and nod my head then they seem to stretch along with the movement of lens.. Is it normal?

How are you doday? I recently got my forst glasses for astigmatiam...and my astimgatiam vision is stil present...
Thank you so much for the explaining. How can I tell if an astigmatism is with or against the rule?
I was diagnosed with astigmatism on November 11th
One of the best explains i watched so far
In the diagram you have shown two focal points from vertical and horizontal meridia...but doesnt it actually is a line of foci for each?
Thanks Crazy for concepts for asking! You are completely right! Sorry for the confusion, my 3D ray drawing needs a bit of work I see :S
I think he's right... They are focal lines when u combine both until then they are focal points for each meridian... Isn't it?
Thank you for explaining the word origins.
Thanks Antonio
Is astigmatism present at every distance? I can see computer screen crisply without glasses but farther away I see double edges of objects.
Yeah astigmatism is present at all distances. Further distances generally make the letter sizes much smaller so the effects are amplified
@@AntonioTheOptom Hmm. So then with purely astigmatism and no myopia, you still can see more clearly close up? If you make the letters on the computer screen small at close distance, do you then see double edges even at that close distance?

can be corrected using lasik or any modern laser procedure provided that you qualify for it .
No eye doctor knows. They just guess. I believe it is lack of Vitamin A (Retinol) and B-Vitamins.
There isn't enough research. Could be genetic, could be an accident during development. Who knows.
Is it normal to have eye strain looking up close with toric contact lenses? My eyes are relaxed looking at the distance but I struggle with reading books etc.
It’s normal to feel strain up close in general regardless of contacts. But can be exacerbated with an incorrect CL prescription
@@AntonioTheOptom I still have my old spherical contacts and with them I didn't have this issue ;/

Hi... I have a qn... Does the image turn again from upside down when it goes past the focal point?
It would turn upside down beyond the focal point !
@@AntonioTheOptom I mean turn back normal?.. cuz normally the image falls upside down...right?
And if it does... Do compound astigmatic people see upside down at the circle of least diffusion?
Sorry mixed astigmatism

I’m 27 years old and just diagnosed with this thing. Everyone at the Eye doc was asking how I went so long without wearing glasses

우와 ㅎㅎㅎ 난시를 이해하는데 도움이 많이 되었어요. 정말 감사합니다 :)
But an eye can have both Myopia and Hypermetropia at the same time due to loss of power of accommodation
that's presbyopia
what is the relationship between astigmatism and keratoconus?
I think I can answer this one. My son's eye doctor thought he might have had keratoconus a while back, and mentioned how important it is that he doesn't rub his eyes too hard. If you have a stigmatism, you're more tempted to rub your eyes and risking damage to your cornea.

My astigmatism has always been very high because of my small eyelids pressuring the cornea

What is AXIS?
What is the best treatment for astigmatism
Spectacles or contact lenses
Thank you so much
If someone had sph +.25 cyl -3.75 180 would that be considered nearsighted or farsighted? Like would they see better close up or far?
Neither! Astigmatism affects all ranges
@@AntonioTheOptom Oh ok. People only talk about myopia and hyperopia, I didn't realize astigmatism was neither

your left eye will be affected because of over prescribed.
Thank you 🤧😭 4:33
Nice sir ❤ fan from india
Tell about retina
good stuff
My optician told me that astigmatism means that your eye is shaped like a rugby ball instead of like a football.
Is astigmatism danger

Okay thanks I'm off to the optometrist
Excellent ... well done ...

You have myopia
IT MAKES SENSE - GREEK, A STIGMA MARKS - STIGMATA HER VISIONS ARE HER PROOF OF HOLY MARKS.
Is astigmatism genetic? Or a developmental fault?
Like all refractive errors including myopia and hyperopia, it's likely a combination of genetics and environmental factors
