Astigmatism is a common eye condition affecting nearly 1 in 3 people. It is caused by an irregularly shaped cornea or lens, which makes it difficult to focus light on the retina. Astigmatism can cause blurred or distorted vision at all distances, and can be accompanied by headaches, eyestrain, and fatigue.
What Causes Astigmatism?
Astigmatism is usually inherited, but it can also be caused by an injury to the eye or a surgical procedure. In some cases, astigmatism can be caused by a person’s natural shape of the cornea or lens.
Who Is Most Likely to Have Astigmatism?
Astigmatism is a common eye condition and can affect people of any age. It is more common in those who are nearsighted or farsighted.
How Is Astigmatism Diagnosed?
An eye care professional can diagnose astigmatism during a comprehensive eye exam. The doctor will use a series of tests, including refraction, to measure the curvature of the eye and determine the amount of astigmatism present.
Can Astigmatism Be Cured?
Astigmatism cannot be cured, but it can be managed with corrective lenses. Glasses, contact lenses, and laser surgery can all be used to correct astigmatism. In some cases, glasses or contact lenses may be the only necessary treatment.
