Question 1

what level of astigmatism is too high for regular contacts?

Accepted Answer

Astigmatism: Contact lens technology has advanced a great deal and a wide range of astigmatism can be corrected.

Question 2

which level of astigmatism is too high for regular contact lenses?

Accepted Answer

Up to : 3.5 diopters of astigmatism can be corrected with soft contact lenses.  With rigid contacts, any amount of astigmatism can be corrected.

Question 3

astigmatism might require corrective lenses or glasses. at what level of astigmatism would i need help?

Accepted Answer

When blurred: Astigmatism is very common -- almost everyone has a little bit.  It simply means that the cornea is not perfectly round, but rather has one steeper and one flatter curvature (like the side of a football rather than a basketball).  People with more than 0.75diopters of astigmatism usually notice that images are blurred without glasses or contacts.

Question 4

what is astigmatism?

Accepted Answer

Oval eye shape: Refractive errors require either plus (farsighted) or minus (nearsighted) glasses + an extra amount if the eye is oval in shape (astigmatism).  These are called refractive errors and can be corrected with glasses or contacts.  The list of other eye problems is long and these are usually unrelated to astigmatism.

Question 5

how bad is astigmatism?

Accepted Answer

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.

Question 6

what causes astigmatism?

Accepted Answer

Irregular Cornea: Astigmatism usually is caused by an irregularly shaped cornea. Instead of the cornea having a symmetrically round shape (like a baseball), it is shaped more like a football, with one meridian being significantly more curved than the meridian perpendicular to it. Astigmatism usually causes vision to be blurred or distorted to some degree at all distances.

Question 7

can astigmatism be cured?

Accepted Answer

Yes: It can be treated with the laser or incisional techniques.  In most cases, astigmatism is not treated surgically but with glasses or contact lenses.  Having astigmatism is normal.  Most people have it.

Question 8

how is astigmatism treated?

Accepted Answer

Contact lenses: The irregularities in the curvature of the cornea can be addressed though customized contact lenses.

Question 9

what does astigmatism mean?

Accepted Answer

Not spherical: Astigmatism means that the front window of the eye, the cornea, is not spherical.  It is shaped like the side of an egg.  

Astigmatism is normal.

Question 10

what happens in astigmatism.?

Accepted Answer

Distorted vision: Regular astigmatism is a refractive error produced when your eye generates an image as if the light rays passed through a glass football. Glasses, contact lenses, or laser vision correction can correct the error so you can see better.
