Astigmatism
In order to see perfectly clearly, any object we look at needs to be uniformly in focus at the back of the eye. Astigmatism occurs when part of the image is always out of focus, causing blurred vision.
What is astigmatism?
Most glasses wearers will have some form of astigmatism. In more developed cases, or without treatment, symptoms could also include:
- Headaches
- Having to squint to see clearly
- Eye strain or tiredness when focusing on prolonged tasks - like when you’re reading a book or a computer screen
What causes astigmatism?
Astigmatism is usually something you’re born with, although it can develop and vary later on in life due to age-related changes. It’s not clear why it happens, but this eye condition is most likely linked to your genetics. You’re also more likely to have astigmatism if you’re short- or long-sighted.
Astigmatism could develop after:
- An eye injury
- Eye surgery
- An eye disease
What help is available?
In most cases, astigmatism is easily corrected with either glasses, contact lenses (called toric lenses), or even surgery.
Your optometrist will be able to detect astigmatism during a routine eye test, and they’ll recommend the best option for you.
Did you know?
Eye tests are bulk billed to Medicare so there are no out of pocket expenses for you.
