What is Astigmatism?
Astigmatism is a common eye condition that affects how you see. In most cases, it happens when the front part of your eye, called the cornea, is not perfectly round. Instead, it has a shape more like a football than a basketball. Because of this, light entering your eye does not focus evenly on the retina. As a result, you may notice blurry or distorted vision. Many people have some degree of astigmatism, but it often goes unnoticed. However, if you struggle with clear vision, astigmatism could be the cause.
Common Symptoms of Astigmatism
Astigmatism can cause several symptoms. Sometimes, these signs are mild and easy to miss. However, they can affect your daily life. Look out for these common symptoms:
For example, if you notice these symptoms often, you may want to schedule an eye exam for astigmatism.
Causes and Risk Factors
Astigmatism happens when the cornea or lens of your eye has an uneven curve. This shape prevents light from focusing properly. There are several reasons why this can occur. For instance, some people are born with astigmatism. Others may develop it after an eye injury or surgery. In rare cases, certain eye diseases can also cause astigmatism.

However, anyone can develop astigmatism at any age.
How Astigmatism is Diagnosed
To find out if you have astigmatism, an eye doctor will perform a full eye exam. During the exam, the doctor may use special tools to measure how your eyes focus light. For example, a device called a keratometer checks the curve of your cornea. In addition, a refraction test helps find the right prescription for glasses or contact lenses. These tests are quick and painless. If you live in a city with good eye care, such as New York or Los Angeles, you can easily find clinics that offer these exams.
Treatment Options for Astigmatism
There are several ways to treat astigmatism. The right option depends on your needs and lifestyle. Most people use corrective lenses for astigmatism. These include:
In some cases, doctors may suggest surgery. For instance, laser eye surgery can reshape the cornea and improve vision. However, not everyone is a good candidate for surgery. Your eye specialist will help you choose the best treatment.
Lifestyle Tips and Prevention
While you cannot always prevent astigmatism, you can protect your eyes and support good vision. Here are some helpful tips:
