Understanding Astigmatism
Astigmatism is a common vision condition caused by the shape of the eye, which can make vision appear blurred or distorted at both near and far distances.
What is astigmatism?
Astigmatism is a very common vision condition that can cause blurred or distorted vision at both distance and near.
It happens when the front surface of the eye (the cornea) or the lens inside the eye is not evenly curved, so instead of being round, it is more like a rugby ball than a soccer ball. This uneven shape means light does not focus at a single sharp point on the retina which causes blurry vision.
Astigmatism is not an eye disease, it is just how your eyes are shaped.
You can have astigmatism on its own, or together with long-sightedness (hyperopia) or short-sightedness (myopia).
Identifying the Common Signs of Astigmatism
Mild astigmatism may not cause noticeable symptoms or need correction.
Higher amounts can lead to:
- Blurred or distorted vision at any distance
- Eyestrain or a feeling that your eyes are working hard
- Headaches, especially after reading, computer work or driving
- Tired eyes when concentrating for long periods
Treatment and How We Can Help
Astigmatism is easily managed in everyday life with glasses or contact lenses. Your optometrist will be able to tell you if you have astigmatism during a routine eye examination and will talk you through the best way to correct it for your visual needs and lifestyle.
