Astigmatism

Astigmatism contributes to blurry vision and is often found in combination with short-sightedness and long-sightedness. Blurred vision occurs because of an irregularly shaped cornea or lens. Vision problems can then lead to other troublesome and painful symptoms like headaches and eye strain.

What is Astigmatism?

Astigmatism is a common refractive error that causes blurred or distorted vision at all distances. With the condition, light entering the eye comes to focus at multiple points, either in front of or behind the retina instead of precisely on it. It usually occurs alongside other vision conditions like short-sightedness or long-sightedness.

People with a mild case may experience slightly blurred or distorted vision at all distances. Those with a more severe refractive error can have vision affected so significantly that it interferes with daily activities. As a result of impaired vision, individuals may also experience uncomfortable symptoms like headaches and eye strain.

What causes Astigmatism?

Astigmatism can be caused by an irregularly shaped cornea; think oval-shaped like a rugby ball, instead of spherical like a football. It may also be caused by an irregularly shaped lens within the eye. As mentioned above, this irregular shape causes light to focus on multiple points inside the eye instead of directly on the retina, leading to blurred vision. The symptoms can remain stable for many years or worsen over time.

Options for Correction of Astigmatism

Sometimes, mild astigmatism doesn’t need to be treated. In other cases, symptoms can be managed long-term with glasses. However, there are also options available for more permanent relief of symptoms. Correcting the refractive error often means no longer relying on glasses or contact lenses. This can be achieved through vision correction treatments, including the following:

FAQs

Can I still get laser eye surgery?

Yes, you can. In fact, laser eye surgery can often be used to correct the refractive error. Read our article about whether you can get laser eye surgery with astigmatism to find out more on the topic.

Can you get Lasik eye surgery for astigmatism?

Yes, LASIK is a vision correction procedure used to correct refractive errors, including this one. It is one of the safest and most precise vision correction options available. Read more on our laser eye surgery treatment page.

Is astigmatism common?

Yes, astigmatism is a common eye problem. It’s estimated that 800,000 people across the UK experience some sort of symptoms of the condition, which is about 50% of people who wear glasses.

Is astigmatism treatable?

Yes, it is treatable. Glasses can often be used to manage symptoms like blurry vision and headaches from eye strain. For longer-term relief, corrective treatment options include laser eye surgery, implantable contact lens and lens replacement surgery. Get in touch to find out more.

Will the condition improve on its own?

No, it doesn’t go away without treatment. Symptoms will either remain the same or they can deteriorate over time. Luckily, there are plenty of treatment options to manage or correct it from glasses through to corrective eye surgery options. Check out our treatment pages or get in touch for more information.
