What is it?

Astigmatism is a common eye condition that causes blurred vision. When a part of the eye is shaped irregularly (typically the cornea), light does not hit the retina (back of the eye) correctly. Most people have astigmatism to some degree, but slight irregularities don’t usually affect vision.

How does it happen?

In most cases, astigmatism is present at birth. It is thought to be hereditary, but its exact causes are unknown. Although, some cases are brought on after an eye injury or eye surgery.

What are the symptoms?

Symptoms of astigmatism may include the following:

  • Headaches
  • Eyestrain
  • Squinting
  • Blurred or distorted vision (especially at a distance)
  • Difficulty seeing when driving at night

What are my risk factors?

As the exact causes are unknown and it is often present at birth, it is hard to pinpoint who is at risk for astigmatism.

How is it diagnosed and treated?

Your eye doctor will perform a comprehensive eye exam to diagnose an astigmatism. The exam will include checking the curvature of your eyes (keratometry), noting how your eyes react to light (refraction), and measuring your visual acuity.

Astigmatism can be treated in a number of ways, including:

  • Eye glasses (the most common treatment option)
  • Contact lenses
  • Orthokeratology (reshaping the eye through the use of specially fitted contact lenses)
  • Laser or refractive surgery

How can I prevent it from happening?

Since the causes of astigmatism are unknown, there is no way to prevent this condition from occurring.
