A Quick Guide to Astigmatism and Natural Ways to Slow Its Progression

An image of a woman squinting to see somethingAstigmatism is a vision problem that starts early in life, and most people have at least a small degree of it in one eye or the other. And if you have a more severe case, then you may need glasses or other corrective therapies. Early intervention is key to preventing this eye problem from getting worse. This usually involves interventions from your eye doctor, but there are also things you can do at home. By adopting these natural remedies, you can help prevent your eye issues from getting worse throughout your life.

What Is Astigmatism?

The lens and cornea of your eyes are smooth and curved equally in every direction. This lets the light focus properly onto the retina at the back of your eyes. The retina focuses the light in one small location to allow you to see. However, if the lens or cornea is rough or curved unevenly, then the light rays canā€™t refract properly. Instead, there are many focal points in front or behind the retina. This causes an eye problem known as astigmatism.

This eye problem is caused by defects in the cornea or lens. Basically, theyā€™re abnormally shaped.

When the cornea is the problem, itā€™s shaped like a football rather than a ball or sphere. This is known as "corneal astigmatism." This shape results in distorted images because light rays canā€™t meet at one common point.

There is also "lenticular astigmatism," which means that the eye lens is misshaped. This is less common than issues with the shape of the cornea, but still occurs.

It isnā€™t an eye disease that causes this vision issue, and the eye is usually otherwise healthy. And it usually occurs very early on in life, so isnā€™t age related.

Symptoms of Astigmatism

Some of the signs that you might suffer from this vision issue are:

  • Blurred vision, which can affect both near and distant objects and is most obvious around the edges of an object
  • Difficulty seeing both near and distant objects without squinting
  • Headaches
  • Blurred vision or pain at the end of the day or after long periods of squinting at small objects like print
  • Eye strain or fatigue
  • Distortions in letters or shapes that make them look compressed, tilted, or thinner than normal
  • Doubled or distorted images

Potential Causes of Astigmatism

There are several factors that can cause or put you at higher risk of astigmatism including:

  • Genetics, which explain why this eye problem can be present at birth
  • Corneal scarring, which can occur after eye surgery
  • An eye injury, which causes scarring that interferes with how the eye muscles develop
  • Keratoconus, which is a disease that causes the cornea to become thinner and change shape
  • Accidents that impact the neck muscles, which are connected with extra-ocular muscles and can affect how the eyes work

It is rumored that reading in dim light, watching TV, and using computer screens for too long may also bring on this eye issue. However, thereā€™s no evidence that this is the case, and these rumors are usually dismissed as myths by medical professionals.

Farsightedness vs Nearsightedness and Astigmatism

An image of a man with glasses reading a bookAstigmatism isnā€™t the same as nearsightedness or farsightedness, but these conditions can occur at the same time.

Near-sightedness is also known as myopia and makes it difficult for you to see things that are far away. Itā€™s very common and is caused by an elongation of the eyeball. In contrast, farsightedness, or hyperopia, is when you have trouble seeing things close to you. Itā€™s caused by a shortening of the eyeball.

Astigmatism can be caused by either one or both of these conditions because they both cause changes in the cornea and retina. This can result in one of these three conditions:

  • Mixed astigmatism, where one principal meridian in the eye is nearsighted and the other is farsighted
  • Hyperopic astigmatism, when one or both principal meridians of an eye are farsighted
  • Myopic astigmatism, which occurs when both primary medians are near-sighted

The meridians of the eye are a bit like lines of longitude on a globe, if you imagine the poles of the eye starting at the pole. The flattest and steepest meridians are called the principle meridians.

Conventional Therapies

If you have a slight astigmatism, then you probably wonā€™t need to undergo conventional corrective therapies unless your condition worsens. However, you should still see an eye doctor to have your condition checked and monitored as it can get worse over time.

If your eye issue does need addressing, then there are several options that your doctor may suggest including:

  • Eyeglasses that correct the sight in one or both eyes
  • Contact lenses
  • LASIK surgery, where lasers are used to reshape the cornea
  • Refractive surgery, which is rarely used these days as it doesnā€™t always work

Improving Your Eye Health at Home

There are also things you can do at home to help improve your eye health and prevent degeneration. However, you still must visit your doctor first to get an accurate diagnosis and any conventional therapies you may need. You should also get an annual eye exam to keep on top of any changes.

You can also make sure to take good care of your eyes. Astigmatism symptoms may get worse if you:

  • Are exposed to lots of UV light from the sun or blue light from electronic devices
  • Eat a poor diet that causes health conditions like high blood pressure, diabetes, or inflammation
  • Donā€™t eat certain minerals, vitamins, or antioxidants that support good eye health
  • Drink heavily
  • Smoke
  • Have a sedentary lifestyle
  • Use drugs

You can also help support good eye health and maybe even prevent astigmatism from getting worse by:

Protecting Your Eyes

Try to avoid looking at devices for long periods and always protect your eyes from the sun with sunglasses or a hat.

Preventing Faster Aging

Eye conditions get worse as you get older, so make sure you avoid lifestyle choices that cause premature aging like smoking and drug use.

Eating an Eye-Healthy Diet

Your eyes need a mix of nutrients for good health. These vitamins will help strengthen the tissues in your eyes, prevent free radical damage and macular degeneration, lower your risk for glaucoma and cataracts, and help prevent eye fatigue. The best vitamins for your eyes are:

  • Zinc
  • Lutein
  • Antioxidants like vitamins E, A, and C
  • Omega-3 fatty acids
  • Zeaxanthin
  • Glucosamine
  • Lycopene
  • Carotenoids

  • Wild caught seafood
  • Grass fed, organic meat
  • Corn
  • Peas
  • Nuts and seeds
  • Red bell peppers
  • Mango
  • Bone broth

Eye Problems and Adrenal Fatigue

Conditions like Adrenal Fatigue Syndrome (AFS) may impact good eye health and the progression of certain eye conditions. AFS is caused by ongoing, chronic stress. The bodyā€™s mechanism for dealing with stress is known as the NeuroEndoMetablic (NEM) stress response. This stress response causes the release of cortisol from the adrenal glands, which then makes changes throughout the bodyā€™s circuits, consisting of related organ systems that help address stress. These changes protect you and help you respond to the cause of the stress.

When stress is chronic, as it often is in the modern world, cortisol levels must remain high over the long term. This results in overwork for the adrenal glands, which can then start to fatigue and decline in health. It can also result in imbalances and malfunctions in the NEM stress response and the bodyā€™s circuits as well as the components of these circuits. The symptoms and health problems which can occurs as a result of this can be very distressing and annoying.

If you have AFS, then it may impact any astigmatism that you already have. AFS can cause chronic inflammation as well as premature aging, both of which may cause this eye condition to progress more quickly. AFS is also strongly linked to a poor diet; itā€™s one of the most common causes of adrenal fatigue, which may also impact eye health.

If you have astigmatism, it may also impact your AFS as it can cause eye fatigue, headaches, and other symptoms. These symptoms will naturally increase your stress levels, which is the root cause of AFS. This is just another reason why itā€™s so important to see a doctor if you have this eye condition or any other health issue that causes you pain or distress.

The Takeaway

Astigmatism is an eye problem that occurs early and usually requires medical intervention. However, this doesnā€™t mean that thereā€™s nothing you can do about this issue. This eye problem can get worse over time under the wrong conditions, so one of the best ways to manage it naturally is to ensure that youā€™re living a lifestyle that supports good eye health. Hereā€™s how:

  1. See your eye doctor regularly for check-ups and conventional interventions.
  2. Avoid lifestyle factors that cause premature aging like smoking, drug use, and a sedentary lifestyle.
  3. Eat a healthy diet that contains all the nutrients your eyes need for good health.
