What is astigmatism?

What is astigmatism?

Astigmatism: Astigmatism is one type of refractive error. Myopia (or nearsightedness), hyperopa (or farsightedness), and astigmatism all can cause refractive error.

How bad is astigmatism?

How bad is astigmatism?

Usually not: Astigmatism is a physical curvature aspect of the cornea and lens of the eye which in effect makes the eye oval. The term astigmatism is from physics and is not usually a bad thing. The correction is a reverse oval in the eyeglasses or contacts. Most astigmatism is small and easily corrected. Sometimes it is large or irregular and that make perfect vision difficult. See your ophthalmologist. ...Read more

Can astigmatism be a symptom of mitochondrial disease?

No: Astigmatism has to do with the shape of the eyeball which is heavily influenced by genetics. It is quite different from what happens inside the metabolism of functioning cells.

Do I have to have annual exam if astigmatism?

Probably not: Astigmatism, an eye ovalness, is relatively stable and generally will not change much year to year. The frequency of needs for eye examinations relate to the underlying health of the eye (do you have diabetes for instance?), your age, medical history and eye diseases. Annual examinations can be a marketing tool to sell more contacts and glasses in some cases. ...Read more

Corneal topography, opd analysis & ray tracing can even differentiate lens vs cornea astigm. ...Read more
