What Is Astigmatism?

Astigmatism results from light being incorrectly focused inside your eye because of a curvature problem with your cornea or lens. With a properly curved cornea and lens, light is focused directly onto the retina on the back inside wall of your eye. When the curvature is wrong, light is focused somewhere else. This causes distorted, fuzzy, and blurry vision.

Astigmatism can occur alongside other similar conditions like nearsightedness (myopia) and farsightedness (hyperopia).

​​​​​​​What Are the Symptoms of Astigmatism?

  • Blurry or distorted vision at all distances

  • Problems seeing at night

  • Having to squint in order to focus vision

  • Eye strain and irritation

  • Vision-related headaches

What Causes Astigmatism?

Astigmatism in children is usually attributed to genetics. Heredity can also be the cause of astigmatism if developed later in life. It can also be caused by an eye injury or as a result of surgery. It is also experienced in connection with nearsightedness and farsightedness.

How Is Astigmatism Corrected?

Eyeglasses: Eyeglasses are a popular option that many people choose. The lenses compensate for the focusing problem created by astigmatism.

Contacts: Some people prefer to wear contact lenses instead of eyeglasses. Check with your eye doctor on which variety will work best for you.

Orthokeratology: Orthokeratology treatment uses a set of lenses you wear while you sleep. They put gentle pressure on your cornea to reshape it. The reshaping allows light to focus correctly inside of your eye. It may take up to a couple of months to reach a clear vision.

Surgery: A variety of surgeries can be performed to reshape your cornea. If your astigmatism is bad enough, corneal or lens replacement surgery may become necessary.
