Astigmatism is a defect of the eye in which light entering the eye is unable to be brought to a single focus resulting in blurred vision at all distances.
WHAT CAUSES ASTIGMATISM?
Astigmatism occurs when the cornea is shaped oblong more like a football than round such as a baseball, which is the normal shape.
Usually astigmatism is hereditary: many people are born with an oblong cornea, and the resulting vision problems may get worse over time. Astigmatism may also result from eye injury that caused scarring on the cornea, from certain types of eye
surgery, or from keratoconus, a disease that causes gradual thinning of the cornea.
WHO IS MOST LIKEY TO HAVE ASTIGMATISM?
It is not only adults who can astigmatic. A recent study from the Ohio State University School of
Optometry, found in 2,523 children, more than 28 percent of them had astigmatism. Children may be even more unaware of the condition than adults, and more unlikely to complain of blurred or distorted vision. Unfortunately, astigmatism can
affect the ability to see well in school or during sports related activities. Yearly eye examinations are key to the detection of astigmatism in both children and adults.
WHAT ARE THE SYMPTOMS OF ASTIGMATISM?
If you have a slight amount of astigmatism you may not notice it at all. In some cases uncorrected astigmatism can produce headaches, eyestrain and blurred vision at all distances.
HOW IS ASTIGMATISIM DETECTED?
Astigmatism can only be detected through a comprehensive eye examination by an eye care specialist.
HOW IS ASTIGMATISIM TREATED?
Astigmatism can usually be compensated for by wearing eyeglasses or contact lenses. Previously people with astigmatism believed they would not be able to wear contact lenses, this was true many years ago however; technology has produced
soft toric contact lenses that have a special correction built into them for both nearsighted and farsighted vision. Depending on the type and severity of your astigmatism, you may also be able to have it corrected with refractive surgery. Your
eye care specialist will be able to discuss all option with you at the time of your exam.
