What is the cause of astigmatism & hyperopia? How can I prevent or maybe reverse them? Please tell something🙏
Thank you for this video! I am still confused about one aspect though; what is the 'axis' of the cylindrical lens? Is it the meridian without any power, or the meridian with power? I still don't understand this. Thank you

Hi Dr., I am having severe headache. I have check my eyesight with different opthalmologist then my regular opthalmologist just to cross check is my given number is correct. I try to use glasses all the time. My number for right eye: Cyl -3; sph none, axis 1.5, VA 6/12 for left eye Cyl none; sph -3.75, axis none, VA 6/6. Please help. Is it fine to have this sort of eyesight.
Good one
Hello Doctor, very Nice Video, Thank you so much, I got a doubt If we got spherical power - then eye ball size is increased ???? and if we get cylinder power then we get change in cornea shape ??? pls explain the anatomy of eye related to spherical and cylinder power problem, pls comment i need this information urgent, if u make video then its great because videos are not available, Thanks in Advance
Doctor, Right eye ( SPH - 3.00,CYL - 2.00 ) & Left Eye ( SPH 0.00, CYL -1.50 ) This is my spectacles Prescription. Because when have wear the contact lenses with less cylindrical power like CYL -1.75 & CYL -1.25 respectively giving the blur view , Please suggest
Sir your video was very informative and easily understood. Could you please also explain how lasik surgery corrects the cylindrical deformity and the chance of it to get back after the operation. Kindly also explain as to why this deformity happens. Thanks and regards, Dheeraj Pandey Delhi, India
Nice info
I like the explanation
Hi all, thanks for uploading. I have an interesting question. The trial frames allow the optician to place cylindrical and spherical lenses as they wish. But, having the cylindrical and spherical lenses with some distance between them will surely have a different effect compared to having a single lens with both cylindrical and spherical power. So are the trial lenses "offset", meaning that you could not put them in the other order (i.e. spherical first, then the cylindrical)?
Dr. Please guide us which glasses is best for kids?
Is it possible to get the Cyl from the sphere and axis? I wrote my sphere and axis, but I forgot to write the cyl
Nice video my problem is I had cateract surguary 4years ago then retina detatched at the macular now I can't get a correct perscription I see 20 /20 in chair but can't see I have to find glasses on street to see 😓

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?
Sir does normal eye glasses have both spl and cyl powers? It only corrects me with contact lenses which have toric lenses
my 3 yr daughter got +0.50 sph and -1.50 cyl, what is means , whether she is not able to see far object or near by object, is plus power of sphere is worse ??
all Right Thank you

A lens can correct myopia and astigmatism at the same time. An example precription will be: -2,00 -1,50 x180 It means that the lens has 2 diopters of negative sphere aswell as 1,5 diopters of negative cyl. The “x180” just indicates what axis the astigmatism correction is orientated.
Thank sir... Now i can understand the concept...

What happens if the optical center of the les is offset by 1 to 2mm for someone having -5.0 spherical, -1.5 cylindrical and 160 axis? I got my lenses changed and my left eye is hurting bad. The eye test at another store is confirming the new prescription. But I'm wondering if the lens was not cut accurately and it's optical center doesn't align with my eye's center. Please reply.

We want to know about types of glasses
Can the power change from spherical to cylindrical over time?. I have been using spherical glasses for 8yrs but recently I lost my glasses, when I checked with a new optometrist he prescribed me cylindrical glasses with 90° axis, but the glasses don't seem to work at all, everything beyond 5ft looks doubled, when I asked about it to the new optometrist he says wear them for a week it will become normal, 4days have past since but no improvement, to be honest my normal vision is worsening. I have no idea what to do now?, should i go back to spherical or cylinderical will be all right if i wore it for a week?

Can I use contact lenses for cylindrical power
I want one detailed technical video. I am generally not satisfied with axis of my specs, because when i turn after wearing it it looks better. I don't understand how they check. Also i think this axis keep changing with time. My cylindrical is more than spherical.

There are many factors which is to be considered. 1. The prescription 2. IPD & Fitting height 3. Proper fitting of the lens in frame. 4. Frame allignment. All the above factors should be considered for proper vision in a spectacles.
