Astigmatism Overview

Regular, annual eye checkups are important for every member of your family.  During the exam, your eye doctor can identify any changes in your prescription or indicators of eye disease.  One condition that affects many people is astigmatism.  While it is a common condition, it needs to be corrected by a qualified eye doctor. At F & M Family Eye Care in Riverdale, GA, Dr. Fred Osayi and his team work to keep your eyes healthy and vision clear.


Basics of Astigmatism

Astigmatism means that the light entering the eye is not evenly focused on the retina in the back of the eye.  The retina sends electrical impulses through the optic nerve to the brain.  So, when the light does not reflect evenly on the retina, your vision can be blurry. 

Why Light Refracts Differently

Light passes through the cornea and passes through to the light sensitive tissue of the retina. Normally, the cornea is rounded with a curve like a baseball.  An eye with astigmatism is more the shape of a football.  This makes it more elongated.  This can cause your vision to be blurry. 

Symptoms of Astigmatism

Both children and adults can be affected by astigmatism.  That is regular eye exams are so important, particularly in children.  Signs to look out for include:

  • Eyestrain
  • Regularly squinting
  • Headaches
  • Blurry vision
  • Difficulty seeing in low light situations or at night.

Your eye doctor will be able to determine if you have astigmatism and adjust your prescription during a regular eye exam. During the exam, your eyes will need to be dilated so that the doctor can fully examine the eye.  It is even possible to have mild astigmatism and not even be aware of it.  Some symptoms can be so mild that it is not causing noticeable vision problems.  Still, regular eye exams can detect the health of the eye and any problems that need correcting.

Vision Correction

If you have been diagnosed with astigmatism, it can easily be corrected with glasses or contact lenses.  While glasses are the simplest way to correct your vision, some people’s lifestyles make contact lenses the better choice.  Contact lenses do provide a wider field of vision but they used correctly.  In some cases, vision can be corrected with refractive surgery.  Your eye doctor will help you decide which option is best for you.
