Astigmatism is a common vision problem that causes blurred vision. It happens when the eye does not focus light evenly on the retina, the part of the eye that receives and processes images. Astigmatism is very common. In fact, most people have a small amount of astigmatism and don’t even know it. But if you have a lot, it can cause headaches and eye strain and cause problems with both near and far vision. Astigmatism can occur in children and adults and often runs in families.
A type of refractive error that occurs when the eye is unable to focus light evenly on the retina, the common signs and symptoms of astigmatism include:
- Blurred vision at all distances
- Eye strain or headaches
- Difficulty driving at night.
If you experience any of these symptoms, it is important to see our Auckland optometrists as soon as possible. Astigmatism can normally be corrected with glasses or contact lenses. In some cases, surgery may be an option to correct this condition.
What causes astigmatism?
Astigmatism occurs when the cornea (the clear front layer of the eye) or the lens (the transparent structure inside the eye that helps focus light) is not perfectly round. This irregular shape prevents light from focusing properly on the retina (the back layer of the eye that converts light into electrical signals sent to the brain), resulting in blurred vision at all distances.
Different types of astigmatism
There are two common types of astigmatism:
– Regular Astigmatism: when your cornea is curved more in one direction than it is in another, like an egg.
– Irregular Astigmatism: when your cornea or lens isn’t smooth and even. It can be caused by conditions like keratoconus (a disorder that causes your cornea to slowly thin and change shape).
The early detection and treatment of astigmatism are important
If you think you may have astigmatism, it is important you see an optometrist for a comprehensive eye exam. The good news is that it is easily treated.
Our optometrists will do a complete eye examination to determine the cause of your blurred vision. We may use the following techniques to examine your eyes:
– Visual acuity test: This test measures how well you see at different distances.
– Retinoscopy: This test is used to determine the refractive error of your eyes.
– Keratometry: This test measures the curvature of your cornea.
– Refraction: This test assesses how the eyes focus light, and it involves placing a series of lenses in front of the eyes.
