Thanks Brother for explaining so well in a 8 mins video with giving example of your case. 💪🙏
A Oscar worthy explanation, great one.
Wonderful to hear about this technology. A really great reason to visit you next year!
Looking foward to it
This is such a clear and accessible explanation of a term I’ve heard many times but never actually understood! 👏🏻
Glad it was helpful!
Excellent video Robert. Really appreciating my new iscription lenes, especially driving at night.
Thanks Mark! Great to get that feedback
Brilliant explanation and very watchable..... never did really understand this previously so Thank you!
You're very welcome!
So THAT explains my chronic headache and my night-time driving difficulties. I've been suffering from Astigmatism for quite a long time but never bothered to wear prescription glasses. Now, I know I should wear them all the time! Thanks Robert.
You're welcome!
Who else here suffer from astigmatism just like me
Great video very well explained ,thank you
Thank you Desmond!
6:20 thats how i feel ! my glasses dont make me go wow much better(not initially) ! your the first person to acknowledge that and its re assuring because i was going crazy.
👍
Finally explained properly.
Thanks
Glad I could help
For some reason, I'm thinking Liam Neeson!
I always thought astigmatism was the curvature of the cornea. I was wrong.
You’re honestly the best optical professional guy EVER Robert 👍👍👍 No eye doctor had ever explained that to me as thorough as you did 👍👍 Now I know how to ask the right questions when visiting the doctor, and certainly I need to find out if any establishment here in Saudi Arabia offers the iScription from Ziess, thank you man 🌹🌹
Hi Hatem, so glad I could help! We actually have clients who come to us from Saudi although I appreciate not everyone can make the journey, especially at the moment... other clients I have spoken to tell me they can't find the same tech over there.
@@thespectaclefactory do stigmastisms have different levels, like very mild to really bad?
Very helpful video 👍
Hi Ivan, thanks for your feedback!
Awesome !
Thanks!
Amazing video
Thank you so much!
❤thank u my son has stigmatizem ..i am pannic and i have dry eyes..
Handsome doc
What eyeglasses are you wearing in this video? The way the lenses fit those frames is brilliant!
Thanks, they are the J F Rey Double Jeu frames - two frames in contrasting shapes fused together. Email me via rob@thespectaclefactory.com if you're interested in a pair
I started wearing acuvue vita toric contacts lenses abt 3 years ago, I can see better than 20/20 with them. Never had issues with comfort either. My most recent rx is OD: -1.25, -0.75x140 & OS: +0.00, -0.75x040. Bc 8.6 dia 14.5. Could there he an explanation to why my right eye is much weaker than the left in the past 10 years? I struggle to read in my left eye sometimes but have good distance vision (a small amt of directional blur, more noticeable in tbe pm) but struggle see clearly past 2 feet in my right eye.
Which are the best cylindrical lenses for astigmatism +3.75D ?
Hello I see perfect but not good at night in which I been told that I have + .50 cylinder in my prescription. Should I only wear my glasses at night or all day.
Great content! My question is if this new technology of profiling the eye and setting a Rx with the more nuanced results actually gets incorporated in the lens production in some way that an equivalent sph/cyl/axis would not normally or is it just a more accurate way to produce the resulting Rx? Would you be able to comment on your experience with someone need astigmatism correction looking through lenses with MORE cylinder than they really need? Would this be the same effect as someone overcompensating their - Sph with a higher value than they need (ex. -3 needed but looking through a -3.50 lens)?
Thank you!
'Need' is difficult terminology, on a philosophical level. How do you determine the power someone 'needs'?
The power required to achieve optimum acuity is probably a better barometer. And yes, iScription should in theory provide this over a subjective Rx because it is forcing the Px to have what is best (based on the above statement) rather than what they prefer subjectively (within reason),
Finally, the resulting lenses are not only optimised with this more precise Rx but by factoring in pupil size and other data to re-optimise the lens design. It's quite complex and actually above my level of understanding.
@@thespectaclefactory Thanks for the detailed response! I would think iScription would, for example, be able to detect more fractional powers of cylinder required, as opposed to the manual cross-cyl exam steps of 0.25. So you mention that this data and other factors get incorporated in the actual lens design - so I presume that in this case, a Zeiss lab would etch out a unique piece of eyeglass for the patient as opposed to using say a stock single vision blank (also Zeiss)?
Is this why when I look at black background with white letters. The letters are fuzzy ?
What Zeiss portfolio of lenses is for astigmatism
What is that pale lavender tint on your glasses? I love it!
Optician here - it's actually an anti-reflective coating that more than likely has a blue light filter - Crizal Prevencia coating has this look.
Thank you for such a detailed explanation of astigmatism. My question: I am sighted in only one eye and sharp vision is paramount. Can you refer us to someone in Central Florida that employs this technology. Thank you!!!
Sorry, I don't know a store in Florida! You could try asking Zeiss US?
Great video! So i have a question...i have 20/20 in one and 20/15 in the other. I have -.50 cyl both eyes with add of +2.00 in both eyes. My problem is i can see perfectly, but its letters and numbers that are not blurry, but doubled or layered. So my question is would lasik fix it?
Thanks! And good question. Most people after lasik surgery will have more than 0.50 astigmatism, so no, lasik would probably make it worse. Glasses are by far your best option.
My eyes, particularly my left eye, are “non spherical”, as in peaks and valleys across the surface. I think this is why glasses only ever “kinda help” my left eye. Thoughts/comments?
Thank you for the video. I am strugling to undestand the eye prescriptions i was given. In the one the cyl is with + and the axis are 90,75 while the other prescription has - and the axis is 180,165. Are they the same prescription just written differently? Thanks a lot
Yes, when you change the cylinder from + to - the axis changes 90 degrees
@@thespectaclefactory thank you very much for your answer! One last question does this change from + to - means different glasses in its interpretation? Thanks a lot!
I have recently had my eyes tested and received the prescription from optician, after receiving my glasses I decided to check the glasses via an online scanner tool to see if the scan tool prescription matched the test done by the optician. The SPH and CYL measurement from the scan tool were very close to my prescription however the AXIS measurement on the scan measured 140 on the right eye where as the the reading on my prescription showed the AXIS measurement of 140 on the left eye. I then proceded to check my previous glasses against my previous prescrption and the same thing happened , the AXIS reading on the scan tool appears on the opposite eye compared to the prescription. Can you explains why this is or is it possible my glasses are being made incorrect.
Those online scanners work quite well, but only with stock finished lenses. If you have a freeform lens or any kind of multifocal, it’s not reliable. If there’s any doubt about your prescription go to your optician. They can accurately verify your lenses using a focimeter in just a couple of minutes.
Unless you have a reason not to trust your optician, I would expect they are far more reliable than online measuring tools.
Of course it is always possible that a mistake was made. You should speak to your optician about it. Let me know what they say!
I have 0.50 in both eyes and (cyl 1.25 in my right eye and 1.50 in my left eye )with axis 160 ,, is laser good for me?
nope and why would you want laser?
Hlo doc
I have -6.00 spherical in both eyes
and -0.50 cyl in both eyes with 180° in left eye and 30° in right.
But m using spectacles with only spherical power.
mild astigmatism can be masked with a shperical spectacles?
Yes, as I explained in the video you can manage with uncorrected astigmatism, but it will be better to have the correction in your glasses
So with this test, it tells you your astigmatism prescription without you telling the doctor what you see better or worse?
Hi there, my eyes were perfect before cataract surgery but after surgery I got induced astigmatism, I want to know can it be corrected on its own without using glasses or I have to use glasses thnx
You'll need to wear glasses
please what is the difference between - and + astigmatism which one can be corrected by Lasik surgery
It's just a different way of recording it. I'm not an expert on laser surgery so I can't answer that I'm afraid.
Do I need new glasses for astigmatism when entering a place where there are many lights, top of my head got weird and feels heavy? Please help
Depends on what your new prescription is compared to your old one. Best to visit your optician to make sure
My astygmatism has changed in a year and a half from 180 axis to 10 axis in my right eye. Is this possible? could my prescription be wrong?
It's definitely possible, but I'd discuss with your optician
That's so nice for me... I have like 0.25 astigmatism and my doctor does 0.5 dioprees and that succesed... I see! Like before... I have this on only one eye so she give me false glass to another... But I driving safely
👍
@@thespectaclefactory especially in night driving with anti reflection glass is really better... But I can't afford full anti reflection gasses so my new Christmas gift is obvious... In my country Czech Republic we have great social kind of safe life emergency but glasses are kind of expensive...hmm I have philosophy questions 😳😄
Hello Do i have astigmatism if my eye sight is still clear but when at night I can't see very well and I can see light streaks or halo at every lights and i am having frequent headaches too..I'm very curious pls help :)
Just get an eye examination and you'll find out. I can't diagnose you over the internet
@@thespectaclefactory okay thank you very much... I'm sorry to add this, and I'm having difficulty seeing at far distance too. And I just noticed that my vision is slightly double that I squint and blink my eyes everytime.
Not mine ..
I have astigmatiam glasses..but i don se clear ...i didn't sen clear even whe my doctor put lesnses for test ...i can't get rid of astigmatiam sight....al the object ..letters,, i see a shadow of them down the initial object..with glasses and ni glasses..i dont know what to to...
Hard to know without diagnosing you in person. Make sure you are going to the best optician you are able to visit
Did your eye doctor mentioned any reason why glasses or none you see the same? A cerrain conditon of the eye's cornea called KERATOCONUS can be one among other reasons, and a special kind of contact lens custom fitted for you will improve your vision (semi-hard or combination hard&soft). But of course that is only one possible reason why? Best see a doctor in your area who will give you thorough examination, clear explanation of your case and best possible correction options.
@@jenniferharish5951 Thank you for replying! My doctor never mentioned KERATOCONUS when she saw me. I discovered KERATOCONUS meaning alone in my research. And yes, I have KERATOCONUS...
were you actually diagnosed with keratokonus?
Something is wrong with my eyes Something causes my sight to go all black florescent green or yellow and red
Strange glasses.
Yeah! One of my favourite pairs
The music on this make it really difficult to hear and is so unnecessary.
Sorry; the newer videos don't have background music
Well not the best explain compared to other which explain almost nothing. I have about 30-45 degrees on both eyes, no one can explain me to understand what exactly this means in visual picture compared to normal picture ... I thoght I have shortsightedness and I have for sure farsightedness.
Astigmatism affects your vision no matter whether you look far away or up close....it is an additional part of a prescription that indicates you have double vision. The two parts of your prescription that indicate astigmatism are the cyl and axis. Cyl is the power for your astigmatism correction and the axis is the Degrees from 0-180 at which the cyl power is rotated
@@bendietrees Tnx but this is not the explanation that I am looking for. I am sure I don't have double vision or this is so slight that is not feelable.
