Astigmatism is a very common eye condition that affects approximately one third of the population. This condition occurs when the cornea (the clear front cover of the eye) is curved or shaped unevenly, which distorts how it focuses incoming light.
Astigmatism usually occurs when the eye grows unevenly, due to genetics or lifestyle factors, such as too much screen time, aging, illness, or a large amount of nearsightedness or farsightedness. It is also more common in people with certain inherited disorders, such as spherocytosis and keratoglobus, as well as people who have had eye surgery.
Although it is not clear exactly why someone develops astigmatism, it can be a very frustrating condition that can affect vision and cause eye strain and fatigue. To manage astigmatism and to prevent it from progressing, it is important to have regular eye exams and to wear eyeglasses or contact lenses, when necessary.

Can astigmatism occur suddenly?
No, astigmatism does not occur suddenly. Astigmatism is a refractive error of the eye caused by an irregular curvature of the cornea or lens, resulting in distorted or blurred vision. It is usually present from birth and can even be hereditary, so it is unlikely that astigmatism would occur suddenly.
Although, in some cases, it can progress to an age-related condition known as presbyopia which can cause blurred vision at all distances. Additionally, an eye injury, eye surgery, or diseases such as corneal scarring, keratoconus, or cataracts could potentially cause astigmatism to develop.
Therefore, although astigmatism can progress or worsen over time, it does not usually occur suddenly.
Why did I get astigmatism later in life?
It is thought that astigmatism is caused by the shape of the cornea, which can change due to a number of different factors. These may include genetics, eye injury or trauma, changes in the shape of the eyelid, aging, and diseases or medical conditions.
It is also possible that astigmatism can develop as a result of prolonged use of contact lenses or other optical aids.
It is important to have regular eye examinations in order to monitor the shape of the cornea and diagnose any changes that may lead to the development of astigmatism. Your optometrist or ophthalmologist will be able to advise you on the best course of action to take should you develop any symptoms or changes in your vision.
Is astigmatism caused by stress?
No, astigmatism is not directly caused by stress. Astigmatism is an eye condition that occurs when the eye does not focus light evenly onto the retina, resulting in blurred vision. Astigmatism is typically caused by an irregularly shaped cornea or lens.
This shape prevents light from being focused precisely on the retina, causing blurred vision at all distances. Stress may, in some cases, aggravate existing vision problems and can cause eye problems if it induces continued eye strain.
However, it is not the underlying cause of astigmatism.
Can rubbing your eyes cause astigmatism?
No, rubbing your eyes will not cause astigmatism. Astigmatism is an eye condition that is caused by an irregularly shaped cornea or lens, which distorts the way light enters the eye. Although rubbing your eyes can cause irritation or redness, the shape of the cornea or lens will stay the same.
If you notice any changes in your vision, particularly blurred or distorted vision, you should see your optometrist to have your eyes checked. It’s also important to note that rubbing your eyes can cause an infection, so if you feel the need to rub your eyes, it’s important to always make sure your hands are clean first.
At what age can you develop astigmatism?
Astigmatism is a condition that affects the shape of the front of the eye, or the cornea, and can cause blurred vision. It is a very common condition that can affect people of any age. While a person of any age can develop astigmatism, it more commonly occurs during childhood.
According to the American Optometric Association, most children develop some degree of astigmatism by the age of three. It is also very common for astigmatism to worsen during adolescence and to remain relatively unchanged until late adulthood, when an increase in astigmatism can occur again due to aging.
Though astigmatism can occur at any age, diagnosing and treating the condition is important in order to maintain good vision.
What habits cause astigmatism?
Astigmatism is a common vision disorder that occurs when the front surface of the eye–the cornea–is unevenly curved or has an abnormal shape. The disorder can cause blurry vision and difficulty seeing objects clearly.
While astigmatism often occurs naturally due to genetic factors, certain habits can increase the likelihood of developing the disorder.
Smoking is one of the most common habits that contribute to astigmatism. Harmful chemicals released by smoking can damage the structure of the eye, including the cornea and lens. Additionally, smokers are more likely to be deficient in vitamins and antioxidants that help keep the eyes healthy.
Another habit that could contribute to astigmatism is eye strain, which occurs when the eyes are used in an unnatural or sustained way, such as staring at a computer screen for too long. Overuse of the eyes can cause them to become weak or fatigued, leading to changes in the shape of the cornea.
Poor nutrition is another important factor that can contribute to astigmatism. Eating a diet that is lacking in essential nutrients such as vitamins and other antioxidants can weaken the eye’s ability to heal itself.
This increases the risk of damage to the eye, including an uneven or abnormal cornea shape.
In addition to these habits, people who are frequently exposed to dusty, dry or windy conditions are at increased risk of developing astigmatism. Exposure to these elements can damage the eye and lead to changes in its shape, so it is important to wear protective eyewear when outdoors.
By avoiding these unhealthy habits and striving to maintain a healthy lifestyle, it is possible to reduce the risk of developing astigmatism over time.
How fast does astigmatism progress?
The speed of astigmatism progression varies from person to person, and is often affected by factors such as age, lifestyle, and any underlying medical conditions that a person may have. For instance, children tend to experience more rapid progression of astigmatism, and this is often due to their rapidly changing eyesight as they develop.
Senior citizens may also experience changes in vision related to astigmatism more quickly, as their eyesight naturally deteriorates over time.
For some people, astigmatism may progress quite quickly, while for others the progress rate is far slower. This is due to the fact that the level of astigmatism can even out, or even improve, as the eye muscles adjust.
As a person ages, the rate of astigmatism may decrease as the eye becomes more accustomed to using corrective lenses, if necessary.
In cases where astigmatism is mild or moderate, it can sometimes be managed at home with simple vision correction methods like reading glasses or contact lenses. However, in more severe cases, medical intervention may be necessary for proper correction.
Regular visits to an optometrist can help monitor the progress of astigmatism and medical treatments, such as eyeglasses or lasers, can be used to correct it.
How do you stop astigmatism from growing?
Astigmatism is a common visual disorder that causes blurred vision due to an irregularly shaped cornea. While there is no guaranteed way to stop astigmatism from growing, there are steps you can take to reduce discomfort and keep it at a manageable level.
First, it is important to have regular eye exams to ensure your eyes are healthy and to detect any changes. An optometrist may recommend corrective lenses such as glasses or contact lenses to help manage your astigmatism and reduce the distortion of vision.
If your astigmatism is mild, you may be able to manage it with special over-the-counter lenses. Depending on the rate of progression, your optometrist might also recommend refractive surgery to reshape the cornea.
In addition to correcting astigmatism, there are lifestyle and dietary habits that can support good vision and overall eye health. Eating foods high in omega-3 fatty acids, such as cold-water fish, can reduce your risk for developing astigmatism.
It is also important to get sufficient sleep and limit exposure to blue light from devices. Additionally, protection from the sun, such as sunglasses, is recommended to shield your eyes from damaging UV rays.
Overall, while astigmatism cannot be prevented entirely, you can attempt to control and slow its progression. Regular eye exams, corrective lenses or surgery, as well as healthy lifestyle choices, are key to keeping your astigmatism at a manageable level.
Why did my eye axis change?
The movement of the human eye is complicated and it is common for the eye axis to shift slightly over time. The most likely explanation for why your eye axis has changed is an alteration in the balance between the four extraocular muscles that help control eye movement.
When these muscles are theoretically balanced, they help maintain the eye axis in a central position. However, any additional strain or tension can cause the eye muscles to pull on the eye in different directions, shifting its axis.
This can happen due to a number of external factors, including eye strain due to long hours of staring at a computer screen or another device, a change in the shape of your eyeball due to aging, muscular fatigue caused by physical activity, or an underlying medical condition such as Graves’ disease, a form of hyperthyroidism.
If your eye axis has changed, it’s important to discuss it with your optometrist. They will be able to assess the underlying cause and provide you with potential remedial measures that could help to correct the issue.
Is there a way to reduce astigmatism?
Yes, astigmatism can be reduced with the help of special corrective lenses, called toric lenses – and with refractive surgery. Toric lenses are designed to focus light so that it enters the eye at the right angle, which can reduce the astigmatism.
Refractive surgery is a procedure that uses lasers to reshape the cornea, which help to reduce the astigmatism. Surgery is becoming increasingly popular, because it is a permanent solution that can help to improve vision and reduce the need for corrective eyewear.
However, it is important that you talk to your doctor or optometrist to decide which solution is best for you.
What should you avoid if you have astigmatism?
If you have astigmatism, you should avoid activities that put excessive strain on your eyes, such as working or playing on digital devices, watching television or movies with intense or bright moving images, vigorous physical activity or sports which require a lot of eye strain, and especially activities which require the eyes to focus quickly or on diffused or blurred objects.
Additionally, it is important to wear polarized or UV protective sunglasses outdoors to prevent further eye strain from the sun’s harsh rays. Finally, a good general practice to adopt is to take regular eye breaks, close your eyes for a few minutes every hour, and give your eyes a rest from any strain.
This can help improve your eye health and reduce any further impacts from astigmatism.
Can you eventually go blind from astigmatism?
No, astigmatism will not cause blindness. However, it can cause blurred vision which may make daily activities more difficult if left untreated. It can also impact peripheral vision, which may cause difficulty in potential safety-related activities like driving.
Although astigmatism is usually diagnosed in childhood, it can also develop later in life, making regular vision checks important.
The most common cause of astigmatism is an irregularly shaped cornea, which can happen if the cornea is misshapen or the eyeball is elongated. Other causes include wearing contact lenses for too long, certain conditions like keratoconus, advanced cataracts, or eye injuries and surgeries.
If one does have astigmatism and their vision becomes blurry, it can be corrected with glasses, contact lenses, or surgery. Laser-assisted in situ keratomileusis (LASIK) is one of the most common corrective surgeries for astigmatism with a high success rate.
Given regular eyecare checkups and corrective measures, astigmatism does not lead to blindness.
Should I wear glasses all the time for astigmatism?
The answer to this question depends on the severity of your astigmatism and what your doctor recommends. Generally speaking, it’s best to wear your glasses or contact lenses as prescribed by your eye doctor even if your vision doesn’t feel blurry.
This is because astigmatism is an ongoing condition, and wearing your glasses can help to keep your vision stable or even improve it over time. Additionally, glasses can help to reduce eyestrain and fatigue that can result from astigmatism.
If you wear glasses all the time, this can provide higher levels of clarity, comfort and protection. However, some people may need to wear glasses only when necessary, such as when driving or using a computer, depending on how strong their prescription is.
Your eye doctor will be the best resource to provide an individualized recommendation tailored to your need.
Can I stop my astigmatism from getting worse?
Unfortunately, it is not possible to stop your astigmatism from getting worse. Astigmatism is a common condition that occurs when the cornea (the clear front part of the eye) or lens (the inside part of the eye) is not curved evenly.
As we age our eyes also change, so it is possible that astigmatism may become more pronounced over time. However, there are treatments available to help manage astigmatism and reduce its effects. Corrective lenses like glasses or contact lenses are the most common option to reduce astigmatism and improve vision.
Laser eye surgery is another option for more serious cases of astigmatism. It is important to visit your eye doctor regularly for eye exams in order to monitor your health and discuss the best options for managing your astigmatism.
