...Astigmatism is an optical defect in which vision is blurred due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. This may be due to an irregular or toric curvature of the cornea or lens. There are two types of astigmatism: regular and irregular. Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens and cannot be corrected by standard spectacle lenses, but can be corrected by contact lenses. Regular astigmatism arising from either the cornea or crystalline lens can be corrected by a toric lens. A toric surface resembles a section of the surface of an American football or a doughnut where there are two regular radii, one smaller than another. This optical shape gives rise to regular astigmatism in the eye. Astigmatism - MayoClinic.com The first spectacle lenses that corrected astigmatism were made in Philadelphia in 1841. Read full entry

That would mean it will be completely the wrong prescription for that eye, so you probably won't see very well. But, go ahead and try, the worst that can happen is that you can't see with it, and you will take it back off. |

Is there a thin lenses for With all these high tech and
uptodate procedures, did
anybody come up to replace
those ugly thick-lensed eye
glasses?

There are thinner and more light weight materials available for astigmatism, but cosmetically they still aren't always great. A good provider will tell you if you are a poor candidate for glasses and should be honest about the cosmetic appearance of the glasses he/she recommends. For the thinnest lens, you want to look for a "high index" material (1.67, 1.70) with an "aspheric" design. This will give you the thinnest, flattest shape possible. These options will cost more but are worth it! For someone with a strong correction, frame style is important too. You want to choose a frame that helps to mask some of the thickness of the lens, not emphasize it. Try to avoid drill mount frames, as they typically can't handle the weight of a thick lens. |

Would I be able to see fine if Just wondering. It would be
very convenient for me if one
eye had astigmatism and the
other didn't for surgical
reasons. Would I still be able
to see pretty good with one
perfectly corrected eye and
one with astigmatism?

You need a complete eye exam. The optometrist or ophthalmologist will be able to tell you how your vision is with or without glasses. Astigmatism basically means that the shape of your eye changed. Astigmatism affects the distance and the close up. |
