Astigmatism, a common vision problem, affects millions of people worldwide. It is not a disease but rather a refractive error like nearsightedness and farsightedness. This guide offers a comprehensive understanding of astigmatism, its causes, symptoms, and treatment options. Whether you have recently been diagnosed, suspect you may have this condition, or simply want to learn more, read on for a complete overview.

What Is Astigmatism?

It's a prevalent condition that affects people's eyesight. It happens when the cornea (the clear front cover of the eye) or the lens (located behind the iris and the pupil) has an irregular shape. Ideally, both the cornea and lens should be perfectly round, but in an eye with astigmatism, they are more oval, like a football. This irregular shape keeps light from focusing properly on the retina, creating blurred or distorted vision. It's possible to be born with astigmatism, or it can develop over time, and it often occurs alongside other eye conditions like nearsightedness and farsightedness. 

What Are the Causes & Symptoms?

Astigmatism is typically caused by a genetic predisposition, meaning it often runs in families. It can also result from an eye injury, a corneal disease, or surgery. The most common symptoms of astigmatism include blurry vision, eye strain, headaches, and difficulty seeing at night. Some people may not even realize they have astigmatism until they have a comprehensive eye exam, as the symptoms can be subtle. On that note, it's important to have regular eye check-ups to detect any issues early and protect your sight. 

How Is It Treated?

Fortunately, astigmatism can be effectively treated. The most common treatment options are prescription eyeglasses or contact lenses, which correct the way light enters the eye. The lenses are specially designed to compensate for the irregular shape of the eye. For those who prefer a more permanent solution, refractive surgery is also an option. The operation changes the shape of the cornea so light is able to focus properly on the retina. Which treatment works best depends on the severity of the astigmatism, the health of the eye, and the lifestyle of the individual.
