The Definitive Guide: Astigmatism | The Frauenfeld Clinic – Myopia …

Astigmatism:  A defect in the eye or in a lens caused by a deviation from spherical curvature which prevents light rays from meeting at a common focus and so results in distorted images.

There are any number of highly detailed sources all over the Web, discussing astigmatism in terms of physiological flaw of the eye.  While we won’t go through the trouble of reiterating all the commonly information here, we will take a closer look at what matters to you:

1.  How is astigmatism measured, and why is this measurement fundamentally flawed?

2.  Astigmatism, the high fructose corn syrup of the vision industry.

3.  Should you actually use astigmatism correction in your lenses?

4.  How to cure your astigmatism

5.  Astigmatism and the problem with close-up focus

6.  Astigmatism in children

I separate these out into individual topics, to be posted here over the coming week (or two, depending on how much time my schedule allows).

What we won’t do, in these posts, is make any claims that astigmatism correction is unnecessary.  Throughout the Vision Improvement Programs as well as the posts on the blog, you will find me advocating slow, measured, and educated changes to your prescription correction.  While we will take a look at why and how astigmatism correction is a more or less engineered deficiency, we should be careful in how we distance ourselves from this type of correction.

We will also take a look at why we want to avoid this:


For most of you who participate(d) in any of my vision improvement programs, it is quite likely that your astigmatism correction has reduced significantly, or has been completely eliminated.  There are some threads in the forum, discussing this:  Forum topics containing astigmatism keyword
