Astigmatism is a common condition that involves an irregularity in the cornea. Normally the cornea is round, but with astigmatism, it is more of an oval. Because of the shape, instead of the light rays going through and bouncing off one site, they hit two. This results in varying degrees of blurriness as you try to focus your eyes. There are ways to correct astigmatism.

Difficulty: Moderately Easy
Instructions
  1. Step 1

    Get your eyes examined. It is a good idea to make eye exams a part of your regular health routine. Children need an exam before starting school. Many times, the first indication of a vision problem is when a child cannot see the blackboard.

  2. Step 2

    Determine the degree of your astigmatism. If a routine eye exam reveals astigmatism and you have not had any symptoms, it may not need correction at that time. If you are experiencing blurred, vision, headaches or eyestrain, correction may relieve these symptoms.

  3. Step 3

    Talk with you eye doctor to determine the type of correction to use. If you choose glasses, the optician will grind the lenses to compensate for the oblong curve of the cornea.

  4. Step 4

    Consider specially made contact lenses. Contact lenses normally rotate when you blink. To correct astigmatism, the lens must return to the original position after blinking. The makers of contact lenses have come up with a way to accomplish this, allowing more people to be free from wearing glasses.

  5. Step 5

    Discuss the option of laser surgery, which received approval in 1997 by the Food and Drug Administration, as a treatment for astigmatism. Talk about risks and side effects with a surgeon who is experienced in this type of procedure.

Tips & Warnings
  • Both optometrists and ophthalmologists have had an extensive education to practice in their field of medicine. Ophthalmologists have earned a medical doctor's degree with a more general education along with their specialty in ophthalmology.
  • Discuss options with your ophthalmologist if astigmatism is the result of scarring of the cornea.
