What Is an Astigmatism


You’ve probably heard the term astigmatism before, in fact, you may even have it. But not many people actually know what astigmatism is or what causes it. Knowing more about astigmatism can help you recognize its symptoms and understand how it is corrected.

What Are the Causes?

Astigmatism is caused by irregularities in the shape of the eye. Corneal astigmatism is caused by an irregularly shaped cornea, which is the clear part of the eye that covers the pupil, iris and anterior chamber. Lenticular astigmatism is less common and is caused by an irregularly shaped lens in the eye. These irregularities cause light to be focused in multiple points rather than one single point on the retina. This makes your vision blurry or distorted, which can cause eyestrain and headaches if left uncorrected.

How Can It Be Corrected?

People with astigmatism often wear glasses or contact lenses just like those with nearsightedness or farsightedness. For adults, Lasik surgery may also be a good option, although they should discuss potential dangers with their doctors. Surgery is generally not recommended for children, as their vision tends to change well into early adulthood.
If you experience problems with your vision, you should see a doctor right away. Children should have regular eye exams to check for astigmatism, as they may not recognize symptoms. Astigmatism will not only make their day to day living harder, it makes it difficult to succeed in school.
