Astigmatism is a common condition that can result in blurred or distorted vision at all distances, varying with the strength of the astigmatism. It can affect people at any age. People with astigmatism are often short-sighted or long-sighted as well.
What causes astigmatism?
The images your eye transmits to your brain are only clear if rays of light passing into your eye focus on a single point on your retina, at the back of your eye.
Astigmatism is caused when either the surface of the eye (the cornea) or the lens behind it, is an irregular shape. Instead of being round, it is shaped more like a rugby ball. As a result, the light doesn’t focus correctly on the retina and the image is blurred
What are the symptoms of astigmatism?
Astigmatism can cause blurred vision when you are trying to focus on activities that require you to see 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 pain in the muscles around your eye.
How can astigmatism be corrected?
If your eye care practitioner confirms you have astigmatism, don’t worry. Nearly half of the population has some form of astigmatism and it can usually be corrected with glasses or ‘toric’ contact lenses.
Soft, toric contact lenses correct astigmatism by compensating for the individual differences in the shape of your eye, enabling light to focus correctly on your retina. If you are short-sighted or long-sighted as well having astigmatism, toric contact lenses will correct these vision problems at the same time as correcting astigmatism.
