Astigmatism. The correction that is exceedingly rare in actual necessity. Yes, you probably didn’t actually have astigmatism the first time they gave you glasses with correction for it. Surprised? Incredulous? Not sure what to think?
Browse this section for science about astigmatism, how-to guides, and a whole lot of students who successfully reversed their lens-induced astigmatism. Odds are you won’t need this complex focal plane correction for long!
(Q&A) High Astigmatism, Low Myopia – Sph. To Cyl. Ratio Control
This Q&A, applicable if you have spherical correction at or below cylinder correction (high cyl to spherical ratio). A repost here from two BackTo20/20 support forum threads. While I only provide case specific support in the forum, you might be able to come to your own relevant conclusions based on reviewing these scenarios. Not sure if my mesurments are very accurate. Having a hard time telling where the actual blur starts. Think this is the astigmatism. For example this [...]

Jaanus’ Optometrist: “Astigmatism Correction Is For Rare, Serious Cases”
Astigmatism correction. Also heads up, huge rant post. If you know your darling eye guru at all by now, you know that he easily gets triggered. Triggered by various words, including 'eye exercises', 'eye yoga', 'palming' (pretend-Bates Internet thing, don't ask), 'genetic myopia', and of course, astigmatism. You know who's got astigmatism? People. People, not including you. At least if you rule out monkey-lens-seller induced astigmatism, the kind you didn't used to have before you started wearing glasses. [...]
Marie: Eliminated -2.50 Diopters Of Astigmatism
File this one under "just with the free guides". This is a great story (and potential motivation). Starting at -3.50 and -2.50 astigmatism correction (yikes, the latter part), Marie makes it all the way down to just -1.75/-2.25 spherical. Best part, zero cylinder (astigmatism) is left, from the initial -2.50. That's a truly huge improvement, from high astigmatism to zero astigmatism. Here is Marie's e-mail: That's how you go to heaven - sending Jake e-mail progress updates. And [...]
Dina: How Astigmatism Fix Cured A Lifetime Of Headaches
Do you get a lot of headaches? Do your glasses (contact lenses) include astigmatism correction? Then you, kitteh, may have astigmatism headaches - and must read this post. ;) The endmyopia Facebook group has only two rules. One of them, the more important one, is: Don't give diopter specific advice. In other words, don't comment "hey I think you should try a -4.50, that sounds about right". Why this no-diopter-advice rule? Well, liability potential for one. But also because in [...]
Yulia: “No F**ing Cylinders!”
Yulia's quite enthusiastic forum update made me smile, first thing this morning. Here it is, maybe it'll have a similar effect on you: Hey Jake, i want to write today the update! i started feeling lots of eye strain in my long distance glasses and i decided to go to my friendly optometrist today. So guess what? Based on what we tried with her i see pretty clear without astigmatism with my normalised as well. That was something completely blowed [...]
