Can you be short-sighted and have astigmatism at the same time?
Yes, you can be short-sighted and astigmatic. There are two different types of astigmatism but three ways in which Astigmatism can be affected. These are classified as:
- Myopic astigmatism-when an eye with astigmatism is short-sighted.
- Hyperopic astigmatism-this refers to when one or both principal meridians are long-sighted.
- Mixed astigmatism-When someone has one short-sighted astigmatic eye and one long-sighted astigmatic eye.
Astigmatism and short-sightedness can be corrected with toric contact lenses, which also cater for those with long-sightedness.
What are the symptoms of astigmatism?
Astigmatism is an eye condition caused as a result of refractive errors which happen when one has an unusual shaped cornea, (like a rugby ball as opposed to the more common spherical football shape). Most astigmatism is regular astigmatism; however irregular astigmatism can also be experienced and is usually a result of an eye surgery which can cause scarring on the cornea.
Regular astigmatism prevents light from being able to focus onto a single point on the retina of your eye. Symptoms of astigmatism include:
- Blurry vision
- Eye Strain
- Trouble seeing at night
You'll find these symptoms all the more noticeable whilst driving or using the computer.
How do you check for astigmatism?
If you experience symptoms of astigmatism, you should make sure you visit your optician for an eye exam. An eye test will be adequate for a diagnosis without the use of special equipment or having to visit the doctors. Once astigmatism is diagnosed, regular eye tests should be undertaken as astigmatism often fluctuates over time and this will ensure you are also wearing the right prescription.
How do you fix an astigmatism?
Astigmatism can be corrected with glasses or contact lenses to alter the way in which light enters the eyes. In some cases, laser eye surgery known as LASIK may even be required.
How can I correct short-sightedness and astigmatism?
