Some eye experts believe that each one of us has some form of astigmatism. But what is astigmatism? In determining what astigmatism is, it is important to understand that astigmatism is one of several conditions that fall under the heading of refractive errors. Corneal astigmatism, the most common form, means that the cornea is irregularly curved. This, therefore, affects the way in which light rays are focused on the eye, which in turn affects vision. Astigmatism is often present with nearsighted and farsighted conditions, which interestingly also result because of refractive deviations. In extreme cases of astigmatism, vision may be likened to looking through a rippling carnival mirror.

The causes of astigmatism are basically hereditary, but it is important to note that injuries can contribute. Basic symptoms may include feelings of eyestrain or irritation, headache, and vision that seems wavy or unclear at all distances. These symptoms may also become more severe, as astigmatism can gradually increase over time. Note that although these symptoms do not mean that you definitely have astigmatism, you should discuss all of your concerns with your eye care professional.

Just as important as the understanding of what astigmatism is, is the understanding that treating astigmatism is both easy and effective. In cases of mild astigmatism, your doctor may suggest that you do nothing more than have your eyes monitored. Usually, corrective lenses, known as Toric lenses, are prescribed to correct astigmatic vision. These lenses are also available in contact form. Finally, surgery may be an option in more severe cases. However, astigmatism generally does not affect lifestyle or performance of any kind once it diagnosed and treated.
