People with astigmatism wear toric contacts, which are designed especially for them.
Toric lenses have two powers in them; there are curvatures at different angles (one for astigmatism, the other for either myopia or hyperopia). There's also a mechanism, which helps keeping the contact lens relatively stable on the eye when you look around or blink. Toric contact lenses cannot rotate on your eye and that helps to provide crisp vision.
 The same materials are used for toric contact lenses as for regular ("spherical") contact lenses, so you choose what lenses are suitable for you: soft or RGP (rigid gas permeable). The lenses are differentiated by their design.
Necessary fitting of toric lens takes more of your eye care practitioner's time and requires more examining than regular contacts. As a result, you can expect that a fitting for torics will cost more than a regular contact lens fitting. The lenses themselves are also more expensive than spherical lenses.
How can you get to know if there is no power for astigmatism? The problem with an astigmatic correction can be solved with a help of lenses' rigidity, which in some way masks the need of astigmatic correction, because your cornea will to some degree conform to the shape of the lens. With soft contact lenses, some eye care professionals solve the problem of astigmatism correction by providing you with a higher-powered spherical soft lens to mask a small astigmatic correction. The results of this way of treating depend on every particular patient In fact the doctor and the patient can make some mistake in the fitting process, besides it may take some trial by both.
Only a few percents of patients prefer RGPs to soft contacts. Because rigid lenses keep their shape on the cornea better than soft lenses, besides they provide crisper vision to people who have astigmatism. This difference in crispness is not noticeable for most people who wear contacts, but if you really worry about your vision, you may appreciate it.
A lot of facts play role in your eye care specialist's recommendations for the type of contact lenses that you should wear: the needed type of vision correction, your style of life, and amount of money you are ready to pay.
