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!

The 3D example is excellent! Much better than the football concept. Thx!

Thank you for explaining the word origins.

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

So helpful! Thanks!

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?

Thanks Antonio

I m Indian medical student. Nice explanation 👌 🙏

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.

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

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

I was diagnosed with astigmatism on November 11th

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'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.

Well, every optical system has its flaws so you can’t ‘eradicate’ aberration, and in the eyes astigmatism is a combination of the corneal and lenticular curvatures. So the most practical way for humans to see better is to wear glasses or contacts!

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 optician told me that astigmatism means that your eye is shaped like a rugby ball instead of like a football.

needs lot of improvement in explaining...he is just reading something blindly
