Astigmatism
What is Astigmatism?
Astigmatism is a very common eye condition that causes blurred
vision either close up or at a distance. This is because the
cornea, the clear-fronted cover of the eye, is irregularly shaped.
We often explain this more easily by just saying the eye
isn't round, it's rugby ball shaped.
Whether you are long-sighted (hyperopic) or short-sighted
(myopic), you can still have some degree of astigmatism.
Symptoms
Slight astigmatism doesn't usually affect vision or require
correcting, however, larger amounts of astigmatism cause distorted
or blurred vision, discomfort and headache. Astigmatism causes your
eyes to work harder, which can make them tired.
The symptoms can range; some people get headaches, others just
plain old blurred vision. Astigmatism doesn't just affect your near
or far vision, it can affect both. Astigmatism can also result in
tired eyes, especially if you are concentrating on anything for a
long period of time. This may be doing things that require looking
up close (like working at a computer or studying) or at a distance
(such as driving).
Treatment
Glasses or contact lenses can be used to correct astigmatism. In
some cases orthokeratology may be an optional treatment.
Your Visique optometrist can easily measure for astigmatism in a
routine eye test, and will talk you through how to correct it.
Vision will be clearer and more comfortable if astigmatism is
corrected - even if a person sees quite well. Your Visique
optometrist can help with any eye problems or concerns, including
astigmatism.
