Astigmatism: Astigmatism can change as a patient ages similar to myopia or nearsightedness. Typically, astigmatism does not increase as fast as myopia but every patient is different. If you are developing a refractive error with includes myopia and astigmatism, an eye examination is invaluable in measuring and tracking your numbers over a long period of time. Thus routine exams (likely yearly) are helpful.

Shouldn't: Astigmatism can change over time. Past age 26, it is rare for myopia to progress until cataract formation. If astigmatism is increasing, you need to see a specialist eye MD to rule out keratoconus, a serious condition of the cornea which is much easier to treat in early stages. Keep your own record of your glasses prescription from your annual exams.

Yes: Some eyes are simply oval in shape, the basic problem in astigmatism. Myopia is an additional feature of eyeglass needs and is independent of astigmatism. Some eyes have only one or the other.

See below: Myopia, or nearsightedness, is usually caused by the eye being longer than the focusing power. Astigmatism is when the cornea (the front window of the eye) is not spherical - more like a football than a basketball.
