WHAT IS ASTIGMATISM

Astigmatism is a common condition that can result in blurred or distorted vision at all distances. It can affect people at any age and often people with astigmatism are short-sighted or long-sighted too. In the UK, nearly half of the people who wear glasses for vision correction have astigmatism.

What causes astigmatism?

Astigmatism occurs when the surface of the eye (cornea)or the lens behind it is not a round shape, but oval like a rugby ball. This distorts the light entering the eye which does not focus correctly on the retina, and as a result the image is blurred.

What are the symptoms of astigmatism?

Astigmatism can cause blurred vision when you are trying to focus on objects at long distances, such as road signs. It can also affect your vision for close activities, such as reading or sewing. If left uncorrected, astigmatism can lead to headaches, fatigue, squinting and blurry vision.

HOW DO I KNOW IF I HAVE ASTIGMATISM?

If you suspect you have astigmatism, use the “find an optician” tool to find an optician near you, then schedule an eye examination.

Astigmatism Eye Test

While you are waiting to see your optician, you can try the following at home:

  1. If you wear glasses or contact lenses, put them on.
  2. Sit about 35 cm (14 inches) away from your computer screen.
  3. Look at the chart with your hand covering one eye. How do the lines appear? Are they all equally clear and sharp?
  4. Follow these steps again to test the other eye.

What do your results mean?
If you do not have astigmatism, the lines should appear sharply focused and equally dark. You may have astigmatism if some sets of lines appear sharp and dark, while others are blurred and lighter. Whatever your result, you must get confirmation from an optician.
