Astigmatism is a common refractive error that can blur or distort vision at all distances. For some, it remains stable over time, while for others, it gradually worsens. Several factors can contribute to worsening astigmatism, including:

• Aging, as the eye’s lens and cornea change shape naturally over time.
• Prolonged screen time, which can cause eye strain and worsen symptoms.
• Eye injuries or surgeries, which can alter the shape of the cornea.
• Progressive conditions like keratoconus, which thins and warps the cornea.

If you’ve noticed increasing vision changes, it’s important to schedule an eye exam to determine the cause and find the right treatment. Learn more about keeping your vision healthy with our blog page.

Understanding Astigmatism

Astigmatism occurs when the cornea or lens has an irregular shape, causing light to scatter instead of focusing properly on the retina. In a normal eye, the cornea and lens have a smooth, evenly curved surface, allowing for clear vision. However, with astigmatism, this curvature is uneven, leading to blurred or distorted sight.

This condition can develop naturally or result from external factors like injuries or surgeries. While some people have mild astigmatism with minimal impact on vision, others may experience significant blurriness, eye strain, and difficulty seeing at night.

Astigmatism often coexists with other refractive errors like nearsightedness or farsightedness and is typically detected during routine comprehensive eye exams.

Factors That Can Worsen Astigmatism

Astigmatism may remain stable for years, but certain factors can contribute to its progression.

Aging & Natural Eye Changes

As we age, the eye’s lens and cornea undergo structural changes. The lens may become less flexible, and the cornea can change shape slightly, which may increase astigmatism. Additionally, age-related conditions like cataracts can further affect vision clarity.

Digital Eye Strain & Prolonged Screen Time

Spending excessive time on digital screens can contribute to eye strain and discomfort, which may worsen astigmatism symptoms. While screens don’t directly change the shape of the eye, they can cause fatigue, headaches, and difficulty focusing, making existing astigmatism more noticeable.

Eye Trauma & Surgical Procedures

Injuries to the eye, whether from accidents or previous surgeries, can cause changes in the cornea’s shape. Even minor trauma can lead to scarring or irregularities that worsen astigmatism. If you experience any eye injury, it’s crucial to seek prompt optometric care to prevent long-term complications.

Progressive Eye Conditions Like Keratoconus

Keratoconus is a degenerative eye condition that causes the cornea to thin and take on a cone-like shape. This significantly worsens astigmatism and can lead to severe visual impairment if untreated. While keratoconus is uncommon, early detection through routine eye exams is key to managing the condition.

Can Astigmatism Be Reversed?

Astigmatism itself cannot be reversed because it’s a structural characteristic of the eye rather than a disease. However, its effects can be managed through corrective lenses, specialty contact lenses, or laser eye surgery.

Managing & Correcting Astigmatism

If you have worsening astigmatism, several treatment options can help improve your vision and reduce discomfort.

Prescription Eyeglasses & Contact Lenses

The most common way to correct astigmatism is through prescription eyeglasses or toric contact lenses, which are specially designed to compensate for the irregular curvature of the cornea or lens. Your optometrist will prescribe the best option based on your individual needs.

Laser Eye Surgery (LASIK or PRK)

For those seeking a long-term solution, laser eye surgery like LASIK or PRK can reshape the cornea, correcting the irregular curvature that causes astigmatism. However, not everyone is a candidate for surgery—your eye doctor can assess whether it’s the right option for you.

Orthokeratology (Ortho-K) Lenses

Ortho-K lenses are rigid gas-permeable contact lenses worn overnight to temporarily reshape the cornea. This provides clear vision during the day without the need for glasses or contact lenses. While often used for myopia control, Ortho-K can also help manage mild to moderate astigmatism.

How to Prevent Astigmatism from Worsening

While some factors affecting astigmatism are out of your control, there are steps you can take to minimize its progression:

• Take breaks from screens to reduce digital eye strain. Follow the 20-20-20 rule—every 20 minutes, look at something 20 feet away for 20 seconds.
• Wear protective eyewear to prevent eye injuries from sports or hazardous work environments.
• Use proper lighting when reading or using digital devices to avoid unnecessary strain.
• Schedule routine eye exams to detect and address changes in your vision early.
