Astigmatism, a common refractive error causing blurry vision, is often detected in childhood. But does it worsen with age? The short answer is complex: it can, but not always, and the reasons are multifaceted. Let's delve into the specifics.
What is Astigmatism?
Before we address the age-related changes, it's vital to understand what astigmatism is. It occurs when the cornea (the front surface of your eye) or lens is irregularly shaped, preventing light from focusing correctly on the retina. This leads to blurred vision at all distances. Different types of astigmatism exist, and their severity varies widely between individuals.
Can Astigmatism Get Worse With Age?
The impact of age on astigmatism is not straightforward. While it's less common for astigmatism to significantly worsen after early adulthood, several factors can influence its progression:
-
Eye Growth and Development: Astigmatism often develops during childhood as the eye grows. In many cases, the astigmatism stabilizes during adolescence or early adulthood. However, some individuals may experience changes throughout their life.
-
Changes in Cornea Shape: The cornea's shape can subtly alter over time, potentially influencing the degree of astigmatism. This is more likely to occur gradually than suddenly. Factors such as eye injuries or certain medical conditions can also impact corneal shape.
-
Age-Related Eye Conditions: Conditions like cataracts, which often develop with age, can affect the refractive error of the eye, potentially increasing or altering astigmatism.
-
Individual Variation: This is a crucial point. The progression or stability of astigmatism is highly individual. Some individuals experience no significant change after adolescence, while others might see subtle shifts throughout their lives.
Does Astigmatism Always Get Worse With Age?
No, astigmatism does not always get worse with age. For many people, the condition remains stable or even improves slightly after the eye finishes growing. Regular eye exams are crucial to monitor any changes.
How is Astigmatism Corrected?
Astigmatism is usually corrected with eyeglasses, contact lenses, or refractive surgery (like LASIK). The type of correction recommended depends on individual needs and preferences. The treatment doesn't prevent further changes but effectively addresses the refractive error at the time of treatment.
What are the Symptoms of Worsening Astigmatism?
If you suspect your astigmatism might be worsening, you might experience:
- Increased blurriness: Noticeably more blurred vision at all distances.
- Eye strain: Increased discomfort and fatigue after focusing on close-up tasks.
- Headaches: Frequent headaches, especially after visual activities.
- Difficulty seeing at night: Reduced night vision and increased glare sensitivity.
When Should I See an Eye Doctor?
Regular comprehensive eye exams are paramount, regardless of whether you have astigmatism or not. If you experience any of the symptoms listed above, schedule an appointment with your ophthalmologist or optometrist immediately. They can perform a thorough examination to assess the condition of your eyes and determine the best course of action.
