Possible Symptoms for Astigmatism

1. Blurry Vision

Astigmatism, a type of refractive error in the eye, causes varying symptoms in individuals, but the most common is fuzzy or blurry vision no matter how far away the object is.[1] Other refractive eye errors like farsightedness and nearsightedness can cause problems seeing up close or far away, respectively. Astigmatism can occur in one eye or both.

2. Squinting

You may not notice that you have astigmatism in one or both eyes, but looking for certain behaviors in yourself or your child can help you recognize the symptoms. For example, astigmatism often causes squinting because you’re trying to see something up close or far away.[2]

3. Eye Problems

Various eye problems might start to occur as a result of your astigmatism. For example, you may have trouble with eye strain because you are trying to force your eyes to see something they can’t. Your eyes may become irritated easily because they are working overtime, and you will also have problems seeing things at night, whether the objects are near or far away.

4. Headaches

The eye strain, squinting, and other issues associated with astigmatism are likely to lead to consistent headaches. Having more headaches than usual and more difficulty concentrating may be signs of astigmatism.

Top 5 Causes of Astigmatism

1. Birth

It is very common for astigmatism to appear at birth, and this is usually caused by the surface of the cornea being differently shaped than normal.[3] Precisely why this happens, however, is still unknown.

2. Development

Astigmatism can often develop on its own over time, in both children and in adults.[4] The reasons for this are also unknown. Notions that reading in low light or sitting too close to a TV can cause the development of astigmatism are false.[5]

3. Injury

In some cases, a person who didn’t have astigmatism can develop it as the result of an eye injury, including being hit or scratched in the eye.

4. Surgery

One of the possible side effects of eye surgery is astigmatism. Of course, this doesn’t keep people from receiving necessary eye surgery, as the condition is very common, could have developed on its own, and is easy to treat.

5. Keratoconus

Keratoconus is a rare condition that causes the cornea to become cone-shaped and thinner over time. This can cause severe astigmatism, which can usually be corrected through contact lenses. However, more drastic measures may be necessary.

2 Ways to Prevent Astigmatism

1. Avoid Eye Injuries

It’s always important to avoid injuring the eyes. When you are playing sports, it’s a good idea to wear goggles so that you won’t get poked in the eye or experience some other eye trauma. Protecting your eyes from the sun, especially if you live in a sunny climate, is also a good idea. Wearing sunglasses and a wide-brim hat outside can help.

2. See Your Eye Doctor

Even if you protect your eyes from injury, astigmatism can still develop. Thus, making regular appointments with your eye doctor and seeking treatment if you ever experience the symptoms of astigmatism is a good idea. Your doctor should be able to tell you if you have developed astigmatism, so make sure you make an appointment at least once a year to have your eyes checked.

Possible Astigmatism Treatment Options

1. Nothing

Sometimes, astigmatism is so mild that no treatment is needed. However, you still need to see your eye doctor in order to find out if your astigmatism needs some sort of corrective treatment or not.[5]

2. Lenses

Glasses or contact lenses are the most common treatments for astigmatism. They usually are the best option as well for those who have trouble seeing for another reason. Certain types of soft contact lenses, also known as toric lenses, work best for people with astigmatism in one or both eyes.[5]

3. Refractive Surgery

Refractive surgery could be helpful if you have severe symptoms or do not want to wear glasses or contacts. The surgery changes the shape of your cornea to correct astigmatism permanently. If you don’t have any other retina problems, corneal scars, or other eye issues, refractive surgery could be effective for you.

4. Cornea Transplant

This is only appropriate in the case of keratoconus that creates severe vision problems for which contact lenses are no longer helpful.[3] However, this treatment option is rare for astigmatism. In most cases, glasses or contact lenses will be appropriate.
