Astigmatism, a common refractive error affecting the eye's shape, can be a source of blurry vision. Many people wonder if their astigmatism can worsen over time. The answer, unfortunately, is complex and depends on several factors. While it's not guaranteed to worsen, it's certainly possible, and understanding the reasons why is crucial for managing your vision health.
What is Astigmatism?
Before exploring whether astigmatism can get worse, let's briefly define it. Astigmatism occurs when the cornea (the eye's clear front surface) or lens isn't perfectly round, like a football rather than a basketball. This irregularity causes light to focus unevenly on the retina, resulting in blurred or distorted vision at all distances. Symptoms can include blurry vision, eye strain, headaches, and squinting.
Can Astigmatism Get Worse Over Time?
Yes, astigmatism can potentially worsen over time, particularly during childhood and adolescence. This is primarily due to the ongoing growth and development of the eye. As the eye grows, the cornea's shape can change, leading to a shift in the degree of astigmatism. However, this growth-related change typically slows down or stabilizes by the early twenties.
Factors That Can Influence Astigmatism Progression
Several factors can influence whether astigmatism worsens:
- Age: As mentioned, the most significant period of potential astigmatism progression is during childhood and adolescence, as the eye is still developing.
- Genetics: A family history of refractive errors, including astigmatism, increases the likelihood of developing or experiencing worsening astigmatism.
- Eye Injuries or Diseases: Trauma to the eye or certain eye conditions can affect the cornea's shape and potentially worsen astigmatism.
- Corneal Surgery: While often corrective, corneal surgeries like LASIK can sometimes lead to unforeseen changes in corneal shape, potentially impacting astigmatism.
How is Astigmatism Diagnosed and Treated?
A comprehensive eye exam is crucial for diagnosing astigmatism. Your optometrist or ophthalmologist will use various tests, such as a retinoscopy or autorefractometer, to measure the degree and type of astigmatism you have. Treatment options usually involve corrective lenses (eyeglasses or contact lenses) or refractive surgery (like LASIK or PRK).
Does Astigmatism Always Get Worse?
No, astigmatism doesn't always get worse. For many individuals, the degree of astigmatism remains stable throughout adulthood. However, regular eye exams are crucial to monitor any changes and ensure appropriate management.
What if My Astigmatism is Getting Worse?
If you suspect your astigmatism is worsening, schedule an appointment with your eye care professional immediately. They can perform a thorough eye exam to determine if any changes have occurred and discuss appropriate management strategies. This may involve adjustments to your current prescription or exploration of alternative treatment options.
Can Astigmatism Be Prevented?
There's currently no known way to prevent astigmatism. However, regular comprehensive eye exams, especially for children and adolescents, are crucial for early detection and appropriate management.
Can I Get Astigmatism Later in Life?
While most astigmatism develops during childhood and adolescence, it's possible to develop or notice astigmatism later in life. This can be due to various factors, including eye injuries, diseases, or age-related changes in the eye.
This comprehensive guide addresses the complexities surrounding astigmatism progression and aims to provide readers with valuable insights into managing their eye health effectively. Remember to consult with your eye care professional for personalized advice and treatment.
