A Closer Look at Astigmatism: What Causes It to Worsen?

Astigmatism is a common eye condition that makes things look wavy or fuzzy, especially when reading small print or driving at night. Most of us have a bit of astigmatism, and it doesn't bother us much. But sometimes, it can get worse and make our vision more blurry. But what causes astigmatism to worsen?

Just like keeping a car running smoothly, understanding what affects our eyes helps us take better care of them.

What is Astigmatism?

Astigmatism is an eye condition that affects how we see the world.

Essentially, it's a problem with how the eye focuses light. Normally, our eyes, shaped like a perfectly round ball, are more oval, like an egg with astigmatism. This irregular shape causes light to focus on multiple points in the eye, leading to blurred or distorted vision.

Types of Astigmatism

There are two main types of astigmatism. Corneal astigmatism occurs when the cornea, the eye's clear front surface, is misshapen. Lenticular astigmatism is due to an irregularly shaped lens behind the cornea.

Each type affects vision differently, and understanding which one you have is key to getting the proper treatment. This distinction helps your eye doctor tailor a treatment plan that brings the world back into clearer focus.

Natural Factors Affecting Astigmatism

A few natural factors affect astigmatism and how it may worsen.

Age-Related Changes in the Eye

As we age, our eyes naturally change. These changes can influence astigmatism. The lens inside our eye can stiffen and lose elasticity, affecting its shape and potentially worsening astigmatism. The cornea may also undergo subtle changes in its curvature.

These age-related shifts are normal but essential to monitor, as they can impact how light focuses our eyes.

Hormonal Changes and Their Impact

Hormones play a surprising role in our eye health. Fluctuations in hormone levels, such as during pregnancy, menopause, or due to thyroid conditions, can temporarily alter the shape of the cornea or lens.

This can lead to changes in astigmatism, making regular eye exams essential during these times to adjust vision correction as needed.

Lifestyle and Environmental Factors

Sometimes, your lifestyle and environment can make astigmatism worse. Here's how.

Effects of Prolonged Screen Time and Digital Eye Strain

In our digital age, prolonged screen time has become a common concern. Staring at screens for extended periods can lead to digital eye strain.

This strain doesn't directly worsen astigmatism but can exacerbate symptoms like blurred vision and discomfort, making existing astigmatism feel more bothersome.

Impact of Poor Lighting and Eye Strain

Similarly, working in poorly lit environments can cause eye strain. Consistent eye strain can temporarily affect vision quality, amplifying the effects of astigmatism.

Ensuring adequate lighting to minimize strain and maintain optimal vision is vital.

Role of Eye Injuries or Surgeries

Physical changes to the eye, such as those resulting from injuries or surgeries, can alter the shape of the cornea or lens. These alterations can potentially worsen existing astigmatism or create new refractive errors.

Post-surgery care and regular check-ups are crucial in these scenarios to monitor and manage any changes in astigmatism.

Health Conditions That May Worsen Astigmatism

Some health conditions can make astigmatism worse. Here are the most notable.

Diabetes and Other Systemic Health Conditions

Diabetes, particularly when uncontrolled, can lead to changes in the eye, affecting vision. Fluctuating blood sugar levels can cause temporary changes in the shape of the lens, influencing astigmatism.

Individuals with diabetes must manage their condition with VIllage Medical providers to maintain regular eye check-ups.

Other Eye-Related Diseases

Certain eye conditions, like keratoconus, where the cornea becomes thinner and cone-shaped, can worsen astigmatism. Additionally, cataracts and other eye diseases that affect the lens or cornea can also impact the severity of astigmatism.

Regular eye exams are essential to monitor these conditions and adjust vision correction as necessary.

Prevention and Astigmatism Management

Regular Eye Examinations for Early Detection and Monitoring

Routine eye exams are key in detecting changes in astigmatism. These examinations allow for early intervention and help monitor the condition's progression.

Eye doctors can adjust prescriptions as needed and guide the management of astigmatism.

Lifestyle Changes to Minimize the Progression

Simple lifestyle adjustments like reducing screen time, using proper lighting, and wearing sunglasses to protect from UV rays can help manage astigmatism.

Maintaining overall health, especially in conditions like diabetes, is also crucial.

Treatment Options: Glasses, Contact Lenses, and Surgery

Corrective lenses (glasses or contact lenses) are common treatments for astigmatism. They correct the uneven curvature of the eye, providing clearer vision.

In some cases, surgical options like LASIK or PRK may be ideal for long-term correction. It's important to discuss with Village Medical's primary care providers to determine the best treatment plan.

Conclusion

Understanding and being proactive about astigmatism are vital in managing this common vision condition. Regular eye exams, lifestyle adjustments, and appropriate treatments can improve vision quality and overall health.
