Astigmatism: Astigmatism FAQs (2023)

HomeConditionsRefractive Errors

By Amber McManes

Most people have a good understanding of nearsightedness and farsightedness, but when it comes to astigmatism, things seem to get more complicated. Even though many people have some degree of astigmatism, it’s not as widely understood as other common vision problems.

This list of questions and answers about astigmatism is designed to offer all the information you need.

What is astigmatism?

Astigmatism occurs when the surface curvatures of the eye’s cornea or lens refract (or bend) light onto more than one focal point within the eye. (Illustrative video)

In most cases, astigmatism is caused by unequal curves in different meridians of the cornea. Think of meridians as lines connecting numbers on the opposite sides of a clock face. For example, a line connecting 12 and 6 is one meridian. The steepest and flattest meridians are called the principal meridians, which typically are 90 degrees apart.

Ideally, all meridians of the cornea are symmetrically curved, like a baseball. This symmetry means that light rays entering the eye from any angle will all be focused onto the same spot.

With astigmatism, the curvatures are not symmetrical. The horizontal curvature might be flatter than the vertical curvature, or vice versa. The curvatures more closely resemble the shape of an American football or an egg.

Due to this asymmetry, light rays are refracted onto multiple focal points inside the eye instead of just one. Depending on the number and locations of those focal points, vision can be blurred or distorted at multiple distances.

How common is astigmatism?

According to the American Academy of Ophthalmology, around one-third of the U.S. population, or one person out of three, has astigmatism.

What does mixed astigmatism mean?

In mixed astigmatism, the principal meridians of the cornea are significantly different in curvature, causing one meridian (the steeper one) to be nearsighted, and the other (the flatter one) to be farsighted.

Mixed astigmatism is relatively uncommon. In most eyes with astigmatism, the principal meridians are both nearsighted or both farsighted, but in different degrees.

What is irregular astigmatism?

Irregular astigmatism is a relatively rare form of astigmatism in which the principal meridians of the cornea are not 90 degrees apart from each other. In some cases, irregular astigmatism is caused by keratoconus or scarring of the cornea from an injury.

The unusual shape of irregular astigmatism makes it difficult to correct with eyeglass lenses or soft contact lenses designed for astigmatism. In many cases, however, irregular astigmatism can be corrected with rigid gas permeable contact lenses.

What makes astigmatism different from nearsightedness and farsightedness?

Astigmatism, nearsightedness (myopia) and farsightedness (hyperopia) are all types of refractive errors. Refractive errors happen when light rays can’t hit the retina properly due to the shape of the cornea, the lens or the eye in general.

With nearsightedness, the curvatures are symmetrical but are too round, or the whole eye is too long from front to back. This causes light entering the eye to be refracted to a focal point in front of the retina, rather than on the retina.

Farsightedness is the opposite — the curvatures are symmetrical but not quite round enough, or the eye is too short from front to back. Light rays that enter the eye end up at a focal point somewhere behind the retina.

With astigmatism, the curvatures are asymmetrical. They are shaped like the side of an American football rather than round like a baseball. This creates multiple focal points of light within the eye, rather than just one. Astigmatism usually occurs along with myopia or hyperopia.

What are the symptoms of astigmatism?

The main symptom of astigmatism is blurry or distorted vision at more than one distance. For example, you might need to squint to see the television and the computer screen. Some people may also notice that things look “wavy,” either in peripheral vision or when looking directly at something.

However, astigmatism isn’t always severe enough to noticeably affect vision. In addition, young children with astigmatism might have always had blurry vision and therefore don’t realize their vision is different than anyone else’s.

Squinting, headaches, eye strain and poor night vision can all be symptoms of uncorrected astigmatism in people who don’t have other vision problems. If you notice these issues in yourself or your child, you should schedule an eye exam to find out whether astigmatism is the problem. Even if you don’t technically “need” prescription lenses (to pass your vision test for a driver’s license, for example), wearing them could significantly reduce headaches and eye strain.

Is astigmatism hereditary?

Some types of astigmatism probably do have a genetic component. According to the American Academy of Ophthalmology, the exact cause of astigmatism isn’t known, but it is more common among people who have a family history of the condition.

Some evidence also suggests that astigmatism is slightly more common in people of Hispanic and African American descent. There is also some evidence that smoking during pregnancy can increase the chances of the baby having astigmatism.

At what age does astigmatism usually occur?

Most people with astigmatism are born with the condition, but it might not be diagnosed until later. It can develop at any age, though, from an injury, other eye conditions, after a surgery or due to other changes in the shape of the cornea.

How is astigmatism diagnosed?

As part of a comprehensive eye exam, your eye doctor can diagnose astigmatism by measuring the curvatures of your corneas and performing tests to see how your eyes refract light onto your retinas.

How is astigmatism measured?

If you have astigmatism, the numbers on your prescription will indicate how much lens power you need to correct for the astigmatism, as well as where the power is needed.

(Video) What is ASTIGMATISM of the EYE? #shorts

The amount of lens power needed is measured in diopters, and the lens power to correct astigmatism is listed in the “cylinder” column. This is because the lens will only have corrective curve in one direction, like a cylinder, to balance the powers of the principal meridians of your eye. The higher the number, the more lens power is needed.

The number in the axis column is the lens meridian that won’t have corrective curve. It is perpendicular (at a 90-degree angle) to the corrective meridian. The meridians are numbered in degrees, with the horizontal and vertical meridians at 180 degrees and 90 degrees, respectively.

See a helpful graph about meridians and learn more about eyeglass lens prescriptions.

Is 20/20 vision possible with astigmatism?

Yes, people with very mild astigmatism can still experience 20/20 uncorrected vision (vision without corrective lenses). However, the letters on the “20/20” line of the eye chart won’t be as distinct as they are for someone with no refractive error.

It is also possible for people with noticeable astigmatism to achieve 20/20 vision with glasses, contact lenses and/or laser vision surgery. However, it will depend on the severity and type of astigmatism.

If the degree of astigmatism is high, corrective lenses might not be able to provide 20/20 vision. Also, some types of astigmatism may not be corrected with lenses but can be corrected with refractive surgery.

Can you get astigmatism if you aren’t born with it?

Yes, it is possible to develop astigmatism if you aren’t born with it, though it is much less likely.

As the eyes grow and mature, their shape can change slightly. Most people with astigmatism are born with eyes that are more egg-shaped (from the front view) than round. It is possible that their eyes can become less egg-shaped over time.

For people born with round, “normal-shaped” eyes, especially for those who have higher degrees of myopia, it’s possible the shape may become less round and more like an egg over time, which can introduce astigmatism.

Astigmatism can also develop due to other eye conditions, an eye injury or after an eye surgery.

Why is my vision still blurry with astigmatism contacts?

The two most likely reasons are that the contacts are new and your eyes are still adjusting, or they are old and your prescription has changed.

If it has been longer than three or four days since you got the contacts, you should return to your eye doctor to make sure the prescription is accurate and that the contacts are fitted properly. Likewise, if it’s been more than a year since your last eye exam, you should see your eye doctor for a comprehensive exam and to have your prescription updated.

Contact lenses for astigmatism are more difficult to fit than regular lenses. It may be a good idea to find an eye doctor whose primary focus is specialty lenses to ensure you get the best type of lens and fit for your eyes.

Can astigmatism go away?

In most cases, very young children “outgrow” astigmatism; however, the likelihood of outgrowing astigmatism decreases after ages 5 to 6.

(Video) Bonus Astigmatism FAQs

After the age of 25, astigmatism will typically stay the same. It can also gradually worsen with age or due to other eye conditions. Fortunately, most astigmatism can be easily corrected with eyeglasses, contact lenses or laser vision surgery.

Can LASIK correct astigmatism?

LASIK and other laser refractive surgeries are usually effective options for correcting regular astigmatism. If you have mixed astigmatism or irregular astigmatism, you may still be a good candidate, depending on your lens prescription.

Be sure to find a laser surgeon who is experienced with astigmatism corrections for an in-depth consultation.

Are glasses or contact lenses better for astigmatism?

Contact lenses and eyeglasses are both safe and effective ways to correct astigmatism. LASIK, PRK and other laser refractive surgeries can also be good options.

Wearing ill-fitting or the wrong type of contacts, or wearing contacts for too long, can make astigmatism worse in some cases. If you know you have astigmatism, talk to your eye doctor to make sure you have appropriate contacts.

Can astigmatism get worse or better?

Unfortunately, astigmatism can worsen over time, and it won’t get any better after around the age of 25. The natural aging process or other eye conditions can cause the shape of the eye to gradually change, which can intensify astigmatism.

However, progressing astigmatism can usually be easily corrected with glasses or contact lenses, just like other progressing refractive errors. It may be best to wait to correct astigmatism with refractive surgery until any progression has stopped.

Contact a local eye doctor to schedule an eye exam if you think your astigmatism is getting worse. It might simply be time to update your lens prescription.

Can astigmatism cause lazy eye?

Yes, uncorrected astigmatism can cause amblyopia, also known as lazy eye. If one eye has significant astigmatism, myopia or hyperopia, the brain can start to “tune out” the visual information from that eye and only use the information from the eye with better vision.

This kind of amblyopia is called refractive amblyopia. In many cases, it can be treated by consistently wearing glasses that correct the astigmatism, along with vision therapies prescribed by your eye doctor.

Why do my astigmatism glasses make me dizzy?

People often need a period of adjustment to get used to a new lens prescription, and that includes glasses that correct astigmatism.

If you have just been diagnosed with moderate or severe astigmatism, or if you had a significant change in your astigmatism prescription, you may feel dizzy or get headaches for a few days while your eyes adjust to corrective lenses.

If it’s been more than a few days, your eyeglasses prescription may be incorrect, or your lenses might not have been made properly. Schedule another visit with your eye doctor to double check that your prescription is accurate.

At what age can children have LASIK surgery to correct astigmatism?

One of the main criteria for undergoing LASIK is that your eyes have stopped growing, which is usually not until at least age 18. Another is that your lens prescription needs to be stable, meaning unchanged, for at least one year. Astigmatism can continue to change (get better or worse) until around age 25.

Having LASIK or another refractive surgery before the eyes are done growing or before vision is stable can lead to vision regression. This is when vision is corrected for a time but then gets worse again because the original reason for the refractive error is still getting worse.

Are glasses always required for astigmatism?

No, not always. Some astigmatism is very mild, and sometimes astigmatism only occurs in one eye while the other eye has clear vision.

Prescription eyeglasses for astigmatism are generally considered optional if your uncorrected vision (meaning your vision without corrective lenses) is 20/40 or better. However, even if your vision is 20/40 or better, you might still end up with eye strain or headaches if you don’t wear glasses.

If it’s been more than two years since your last eye exam, you should visit your eye doctor to make sure your prescription hasn’t changed. During your exam, your doctor can show you how well you can see with glasses. Even if you don’t technically “need” them, you may be surprised how much clearer the world is with your astigmatism fully corrected.

Will astigmatism get worse if my glasses prescription is wrong?

Wearing glasses can’t make astigmatism worse, even if they are the wrong prescription. Astigmatism is caused by the shape of the eye’s cornea or lens, and glasses can’t change those.

However, wearing glasses with an incorrect astigmatism prescription can cause other problems, including blurry vision, eye strain and headaches. Depending on how “wrong” your prescription is, your corrected vision may not be legal for driving.

You should see your eye doctor at least every other year to make sure your glasses prescription is up to date. (If you wear contact lenses, you should have annual eye exams.)

Can cataract surgery cause astigmatism?

Yes, it is possible for astigmatism to be induced by cataract surgery. It’s also possible for mild astigmatism to worsen due to cataract surgery.

Cataract surgery requires an incision through the cornea. Sometimes, the way the incision heals ends up changing the cornea’s curvature. Astigmatism after cataract surgery may also be caused by the lens implant used.

Corneal healing after surgery isn’t always predictable, but a lot of the risk of astigmatism after cataract surgery can be avoided by finding an experienced cataract surgeon. If you do develop astigmatism after cataract surgery, it can often be corrected with glasses or a follow-up refractive surgery.

Can wearing contact lenses cause astigmatism?

It is possible to develop contact lens-induced astigmatism. If you wear your contacts for too long or they don’t fit properly — or both — they can reduce the amount of oxygen your corneas receive.

This kind of astigmatism can usually be reversed by not wearing contacts for a while and then wearing a different type of lens afterward. It’s important not to wear contact lenses for too long. Talk to your eye doctor about how long is appropriate for you to wear your contacts; it isn’t the same for everyone or every type of lens.

Astigmatism: Astigmatism FAQs? ›

Like other refractive errors, astigmatism tends to cause blurry vision. Unlike myopia (nearsightedness) and hyperopia (farsightedness), the blurriness doesn't occur only at one distance level. Any blurriness or distortion created by astigmatism affects your vision whether objects are close up or far away.

What should you avoid if you have astigmatism? ›

Avoid glare on TV and computer screens. Place your TV or computer screen where lights do not reflect on the screen. Some people find it easier to work on a computer in a dimly lit room. Special non-glare screens that fit over the computer screen also may help.

What can make astigmatism worse? ›

Astigmatism frequently worsens with age. Your cornea can become more irregular due to pressure from your eyelids as they lose muscle tone. Astigmatism generally stays stable until your turn 50. After then, your lens curvature progressively worsens each decade.

Do people with astigmatism need to wear glasses all the time? ›

What Level of Astigmatism Requires Glasses? You'll likely need glasses if your astigmatism has a strength of 1.0 or more. But even if your astigmatism needs less than 1.0 diopters of correction, it doesn't mean you won't need glasses.

What are the rules for astigmatism? ›

With the Rule Astigmatism

In this, the two principal meridians are right-angled to each other, with the vertical meridian being steeper than the horizontal. [12] This type of astigmatism requires a concave cylinder at 180 ± 20 degrees or a convex cylinder at 90 ± 20. This is called a with the rule astigmatism.

Astigmatism is a common visual impairment for which many veterans may not realize they could collect disability compensation.

Can stress make astigmatism worse? ›

Circulatory issues caused by stress and tension are as well as causes of astigmatism. In this case, an accumulation of stress and tension in the neck muscles can lead to a restriction of blood flow to the head and eyes.

Does eye rubbing worsen astigmatism? ›

Rubbing your eyes is one habit that could cause astigmatism. In fact, frequent rubbing could eventually change the shape of your corneas. Rubbing also increases your risk of keratoconus, a condition that makes the corneas thin and cone-shaped.

What problems can astigmatism cause? ›

6 Problems That Are Linked to Astigmatism

  • Amblyopia ('lazy eye') ...
  • Keratoconus.

What is the main cause of astigmatism? ›

What causes astigmatism? Astigmatism happens when your cornea or lens has a different shape than normal. The shape makes light bend differently as it enters your eye, causing a refractive error. Doctors don't know what causes astigmatism, and there's no way to prevent it.

Can you have 20 20 vision with astigmatism? ›

Astigmatism Symptoms

Astigmatism patients often continue to experience vision problems even after receiving corrective lenses for nearsightedness or farsightedness. Astigmatism can make it seem like you are nearsighted and farsighted at the same time. You can have 20/20 vision and still have astigmatism.

What is considered severe astigmatism? ›

Between . 75 and 2 diopters is considered mild astigmatism. Between 2 and 4 diopters is moderate astigmatism, and 4 or more diopters is considered significant or “bad” astigmatism. Generally, eyes with 1.5 diopters of astigmatism or more require correction.

Can people with astigmatism drive? ›

With astigmatism, driving at night is dangerous. Proper glasses can lessen that danger, bending the light before it reaches your eyes to reduce glare, halos, streaks, and general blurriness so that you can keep your focus on the road.

Can someone with astigmatism get Lasik? ›

LASIK eye surgery is an effective type of laser-assisted refractive surgery that can be used to treat common vision problems including astigmatism, myopia (nearsightedness), and hyperopia (farsightedness).

What do lights look like with astigmatism? ›

Lights with astigmatism are well-known for appearing fuzzy, streaky, or encircled by haloes, particularly at night. The lights seem that way because of the distorted cornea, which hinders adequate light intake in your eyes, causing the lights to scatter.

Do people with astigmatism see lights differently? ›

Astigmatism can make your vision blurry and particularly affect your night vision. You may notice that lights look fuzzy, streaky, or surrounded by haloes at night, which can make driving difficult.

How long does it take for glasses to correct astigmatism? ›

Astigmatism is an eye condition that leads to blurry vision caused by the irregular shaped cornea. It takes quite a time especially with astigmatism, it can take 3 to 4 days. It can go on for a week or 5 to 6 days if you have moderate or severe astigmatism.

What are two conditions of people with astigmatism? ›

You have corneal astigmatism if your cornea has mismatched curves. You have lenticular astigmatism if your lens has mismatched curves. Either type of astigmatism can cause blurred vision.

What are the benefits of astigmatism? ›

The benefits of astigmatic keratotomy include: Corrected vision, often to 20/40 or better. Money saved on glasses and contacts each year. No bandages or stitches required.

Are astigmatisms hereditary? ›

Astigmatism is thought to be hereditary, so if you have astigmatism, chances are good your children will have it also. The condition often occurs with other vision conditions such as nearsightedness (myopia). Many people confuse astigmatism with "lazy eye" (amblyopia).

Does astigmatism affect the brain? ›

Astigmatism, a refractive error in which visual images do not evenly focus on the retina, modulates visual perception, and the accompanying neural processes in the brain.

Can astigmatism cause dizziness? ›

Astigmatism Symptoms

The main symptom of astigmatism is blurred vision. This blurriness can lead to squinting, headaches, and even lightheadedness. Most people notice that the blurriness is worse at night. Struggling with nighttime driving is the main reason people seek out treatment.

Can astigmatism cause anxiety? ›

When your vision is misaligned, it can cause blurred or possibly double vision resulting in dizziness, imbalance with walking, and visual over-stimulation (such as crowds, carpet patterns, busy wallpaper, malls, high ceilings, freeway driving, etc.) resulting in feeling anxious and overwhelmed.

Why does squinting help astigmatism? ›

This study revealed that, in simple myopic astigmatism, squinting induces a focus shift in the opposite directions in WTR versus ATR astigmatism.

Do tired eyes make astigmatism worse? ›

You are tired so your visual system is fatigued. You have a refractive error such as long-sightedness or astigmatism. During the day, you may be able to compensate for these, but when your eyes are tired, your vision can go blurry. You could be mildly short-sighted.

Does squinting improve astigmatism? ›

They also found that squinting decreased astigmatism and increased aberrations in the ATR astigmatism groups but had the opposite effect for emmetropia and WTR astigmatism: it increased astigmatism and decreased aberrations.

Are people with astigmatism more sensitive to light? ›

However, with more advanced astigmatism, there can be a variety of symptoms including: Blurred vision. Light sensitivity (photophobia). Eye strain and fatigue (especially after long periods of concentration, such as when using a computer).

Does astigmatism cause your eyes to water? ›

itchiness. tearing (watering) of the eyes. pain. blurred vision.

Does astigmatism cause headaches? ›

Vision problems are one common cause of headaches. Headaches are a known possible side effect of astigmatism. If you have astigmatism, it means that your cornea is misshapen in a particular way – in this case, like a football.

What deficiency causes astigmatism? ›

If you are deficient in vitamins that can improve astigmatism, like vitamin A, you should eat some extra servings of the vegetables mentioned or consider taking a vitamin supplement. Supplements can be great options, so long as you make sure you are taking the correct serving.

What percent of the population has astigmatism? ›

Astigmatism is not as common as nearsightedness and farsightedness, but about 8.4 percent of the population has it. Fortunately, the professionals at Today's Vision Creekside can treat the refractive error, helping you to see more clearly.

Is it harder to see at night with astigmatism? ›

Does astigmatism make it hard to drive at night? The oblong shape of eyes with astigmatism distorts light, making you struggle to see when driving at night. “It's pretty common to see halos around lights while driving at night,” says Dr. Bajic.

Do blue light glasses help astigmatism? ›

Blue light blocking lenses

In fact, excessive screen time can even cause digital eye strain, particularly for those with uncorrected astigmatism. Fortunately, blue light blocking lenses can alleviate this discomfort, and make working on your laptop or texting on your phone much more enjoyable.

What type of glasses are best for astigmatism? ›

Flatter frames are better for astigmatism. Wraparound or curved frames can bend the light in a way that distorts your vision. Also, be sure to choose a frame that sits securely on the bridge of your nose to keep your vision clear and in focus.

What happens if astigmatism is overcorrected? ›

In an overcorrection, the person could end up with astigmatism in the other direction,” he says. In either case, person might still need glasses or contacts to see clearly, he adds.

LASIK does have limits, however. It can only correct up to 5.00 diopters of astigmatism. However, this covers most patients with astigmatism.

What is the power range for astigmatism? ›

Most people have between 0.5 to 0.75 diopters of astigmatism. People with a measurement of 1.5 or more typically need contacts or eyeglasses to have clear vision.

What can trigger astigmatism? ›

Astigmatism may be present from birth, or it may develop after an eye injury, disease or surgery. Astigmatism isn't caused or made worse by reading in poor light, sitting too close to the television or squinting.

What foods help astigmatism? ›

Some of the best nutrients to add to your diet if you have astigmatism are zinc, magnesium, and calcium. You can get high servings of zinc by eating lima beans, oysters, and poultry. Magnesium is found in pumpkin seeds, soybeans, black beans, sunflower seeds, and halibut.

What makes astigmatism better? ›

Wearing corrective lenses treats astigmatism by counteracting uneven curvatures of your cornea or lens. Types of corrective lenses include: Eyeglasses. Eyeglasses are made with lenses that help compensate for the uneven shape of the eye.

What are the two most common causes of astigmatism? ›

Astigmatism is usually caused by your cornea having an irregular shape. Eye care specialists call this corneal astigmatism. You can also have lenticular astigmatism, where the lens in your eye has an irregular shape. Lenticular astigmatism is often caused by cataracts.

Can astigmatism make you feel off balance? ›

Does astigmatism get worse when tired? ›

Blurry eyes at night

You are tired so your visual system is fatigued. You have a refractive error such as long-sightedness or astigmatism. During the day, you may be able to compensate for these, but when your eyes are tired, your vision can go blurry.

How do you stop astigmatism from progressing? ›

The natural aging process or other eye conditions can cause the shape of the eye to gradually change, which can intensify astigmatism. However, progressing astigmatism can usually be easily corrected with glasses or contact lenses, just like other progressing refractive errors.

How do you slow down astigmatism? ›

Astigmatism Treatment. Glasses or contacts can correct almost all cases of astigmatism. But if you have only a slight astigmatism and no other vision problems, you may not need them. If you have a common level of astigmatism, you'll probably have corrective lenses, like glasses or contacts, or surgery.

How do you live with astigmatism? ›

For mild astigmatism, most people can successfully live with the condition by wearing glasses or contacts to correct their vision. For people who don't want to wear glasses or who have severe cases, there are other alternative options such as LASIK, PRK, or Visian Implantable Contact Lenses (ICLs).

How rare is astigmatism? ›

Astigmatism is a common refractive error, occurring in about 1 in 3 of all people. Astigmatism is often present at birth but it can also develop over time, and most often occurs with myopia (nearsightedness) or hyperopia (farsightedness).

Can exercises help astigmatism? ›

Many people believe that astigmatism is only can be corrected by medical intervention when it can easily be alleviated and even corrected through eye training exercises. In fact, there have been cases where with the right exercises in the right frequency yielded considerable results in just one day!

How do you deal with astigmatism at night? ›
