What is astigmatism?

Astigmatism means the surface of your eye — your cornea — is misshapen and therefore doesn’t focus the light that enters your eyes into sharp, clear images. Uncorrected astigmatism results in blurry and/or double vision. You may notice this when you’re reading or performing other tasks that require close-up vision.

Many people have some degree of astigmatism; glasses and contact lenses can usually correct mild to moderate cases. Severe astigmatism may be a bit harder to correct, but the providers at Santa Rosa Optometry have the expertise to find the best option to correct your condition and give you clear, precise vision so you can see and function normally, without discomfort.

What causes astigmatism?

Astigmatism is usually genetic. However, some diseases of the cornea, such as keratoconus, can cause astigmatism. An injury to your eye can also change the shape of your cornea, resulting in astigmatism.

How do I know if I have severe astigmatism?

If you have difficulty driving or performing daily activities because of blurry vision, you may have severe astigmatism. Other common signs of severe astigmatism include:

  • Eyestrain
  • Squinting
  • Headaches
  • Poor night vision

A comprehensive eye exam at Santa Rosa Optometry will help determine if you have astigmatism and whether it’s mild, moderate, or severe.

How is astigmatism treated?

Astigmatism is measured in diopters; mild cases have lower diopter numbers, while more severe cases have higher diopters. Treatment options for astigmatism depend on your diopter score.

The following are general estimates based on diopter range:

  • Diopter of 0-1: no correction required
  • Diopter of 1-3: glasses or toric contact lenses
  • Diopter of 3-5: rigid gas permeable lenses may be an option

If you have a diopter of 5 or higher, a surgical procedure may be needed to correct your astigmatism. If you need eye surgery, your Santa Rosa Optometry provider will work with you to find a specialist who is an expert in surgical correction of astigmatism.

The caring providers at Santa Rosa Optometry will discuss all of your options, and help you find the solution that is best for your individual needs. To learn more or to schedule an exam, call Santa Rosa Optometry today, or make an appointment online.
