Astigmatism: Symptoms, CAUSES and SOLUTIONS
What is astigmatism?
Astigmatism is a very common refractive (optical) problem of the eye. As there is nothing that the eye can do to adjust for this particular error, even low levels can cause eye strain, headaches and blurred vision for both distant and near near tasks.
The cornea is the transparent window sitting above the coloured iris and the pupil (the hole that allows light to pass through to the retina on the back of the eye. It contributes a large part to the optical power of the eye. The cornea can be perfectly shaped like the surface of a soccer ball, but if it's more like a rugby ball (one long flatter curve and one short steep curve) it induces astigmatism, the result is blurred vision. Astigmatism can be present from early childhood or may develop over time.
Common Symptoms Of Astigmatism
Astigmatism can affect you at any time, so it is necessary to be aware of the signs it's present. The most common symptoms include:
- Eye strain
- Distorted or blurred vision at all distances
- Difficulty driving at night
When vision begins to appear blurred or fuzzy over time, a visit to an optometrist is required. Some vision problems can be symptomatic of a more serious disease which would require treatment. In the case of astigmatism, if it is constantly changing, it can be a sign of a condition known as keratoconus.
Testing For Astigmatism
Testing for astigmatism is always part of a comprehensive eye test. It is important to watch for changes in your vision. Besides astigmatism, it helps you detect any common vision problems. If you notice any changes in your vision, visit your optometrist for a comprehensive eye examination.
Can Astigmatism Be Cured?
No "cure" for astigmatism exists, however, in most cases, it's easily corrected with spectacles or contact lenses. Refractive surgery can also be used to correct astigmatism.
