Astigmatism De-mystified

eye conditions at eye and lasik in greenfield massachusetts If you have been told you have astigmatism and are wearing contact lenses or glasses that correct for it you are not alone. Astigmatism is common and can affect both children and adults but what is it, exactly?

Astigmatism is a type of “refractive error.” Refraction is how light bends as it passes through one object to another. It’s a condition in which the eye does not focus light evenly onto the retina; it’s found in connection with both nearsightedness and farsightedness. Light entering the eye is not focused on a single point on the retina so objects near and far become blurred or distorted – like looking through a pane of wavy glass. The cornea of a normal eye is round, like a basketball; a cornea with astigmatism is shaped like a football. This can cause images to appear stretched and blurry.

Some of the most common signs and symptoms of astigmatism include:

  • difficulty driving at night;
  • headaches;
  • eyestrain;
  • difficulty reading small print;
  • distorted or blurry vision at all distances
  • squinting

If you currently wear contact lenses or glasses and are experiencing these symptoms, you may need to update your prescription. You may have mild astigmatism and not know it.

It’s important to remain aware of any changes you notice in your vision – whether you wear corrective lenses or not – and to inform your eye care professional of the changes. Astigmatism is usually found during a comprehensive eye exam which includes dilation.

The easiest and simplest way to correct astigmatism is with glasses or contact lenses. Refractive LASIK surgery may be done to reshape the cornea. Your unique lifestyle will affect the way your astigmatism is treated.

If you feel glasses or contact lenses limit your activities, LASIK may be the right choice for you.
