Astigmatism, a common refractive error affecting the eye's ability to focus light correctly, doesn't typically worsen progressively throughout adulthood. Unlike conditions like myopia (nearsightedness) which can change significantly during childhood and adolescence, astigmatism often stabilizes after the teenage years. However, certain factors can influence its apparent severity or lead to changes in prescription needs. Let's explore these in detail.
Does Astigmatism Get Worse with Age?
While astigmatism itself rarely worsens significantly in adulthood, the perceived worsening might stem from other eye conditions that develop with age. This is crucial to understand. Age-related changes in the eye's structure can lead to changes in refractive error, making it seem like astigmatism is getting worse, when, in fact, it's a related issue.
What Eye Conditions Can Mimic Worsening Astigmatism?
Several conditions, often developing with age, can impact visual acuity and require changes in prescription, sometimes misinterpreted as astigmatism worsening:
-
Presbyopia: This age-related condition makes it difficult to focus on near objects. As you age, your lens's ability to accommodate diminishes, making it harder to focus, potentially impacting the perceived clarity and seeming like your astigmatism has worsened. However, it's a separate issue requiring different corrective measures (like reading glasses).
-
Cataracts: Clouding of the eye's lens can significantly impact vision, blurring your sight and altering the way light refracts, leading to changes in your prescription which may resemble a worsening of astigmatism.
-
Corneal Changes: The cornea's shape can alter slightly over time due to various factors, including injury, disease, or even environmental effects. These changes can affect the refractive power of your eye, requiring a prescription adjustment. This isn't inherently a worsening of pre-existing astigmatism but rather a change in the cornea's overall shape.
Can Eye Injuries or Diseases Worsen Astigmatism?
Trauma to the eye, particularly injuries involving the cornea or lens, can potentially alter the eye's shape and refractive power, leading to changes in astigmatism. Similarly, certain eye diseases like keratoconus (a progressive thinning of the cornea) can significantly worsen astigmatism over time.
Does Eye Strain Cause Astigmatism to Worsen?
Eye strain itself does not cause astigmatism to worsen. While excessive near-work can exacerbate symptoms of existing astigmatism by inducing fatigue, it doesn't change the underlying refractive error. However, persistent eye strain might indicate an underlying vision problem that needs to be addressed by an eye care professional.
When Should You See an Eye Doctor About Astigmatism?
It's crucial to consult an ophthalmologist or optometrist if you experience changes in your vision, including blurred vision, eye strain, or headaches, even if you already have a diagnosis of astigmatism. They can assess whether your astigmatism has truly worsened, or if another condition is impacting your vision. Regular eye exams, especially as you age, are essential for monitoring eye health and detecting any problems early.
