Astigmatism is a common refractive error affecting the eye's shape, causing blurred vision at all distances. While astigmatism often develops in childhood, it can also change throughout life. Understanding the factors that can potentially worsen astigmatism is crucial for managing vision and ensuring clear sight. This article will explore the potential causes and answer some frequently asked questions.
Does Astigmatism Always Get Worse?
This is a key question many people with astigmatism ask. The simple answer is: not necessarily. For many people, astigmatism stabilizes during adulthood, remaining relatively unchanged. However, it's possible for astigmatism to worsen in certain circumstances. The degree of change varies significantly among individuals.
What Factors Can Cause Astigmatism to Worsen?
Several factors can influence the progression or worsening of astigmatism:
1. Age and Development:
Astigmatism often develops in childhood and can change during periods of rapid eye growth, particularly during adolescence. This is because the cornea and lens are still developing and shaping. Once eye growth slows in adulthood, astigmatism tends to stabilize.
2. Eye Injuries or Infections:
Trauma to the eye, including corneal injuries or infections, can significantly alter the shape of the cornea, leading to a worsening of astigmatism. Even minor eye injuries should be evaluated by an ophthalmologist to assess any potential impact on refractive error.
3. Eye Surgery:
While eye surgeries like LASIK or PRK are often used to correct refractive errors including astigmatism, there's a small chance they might inadvertently alter the corneal shape, leading to a change in astigmatism. This is a relatively rare complication but a factor to discuss with your surgeon before undergoing any procedure.
4. Certain Medical Conditions:
Some medical conditions can affect the eye's structure and contribute to changes in astigmatism. Keratoconus, for instance, is a progressive corneal disorder that causes the cornea to thin and bulge, leading to irregular astigmatism that worsens over time.
5. Genetics:
While not a direct cause of worsening astigmatism, genetics play a significant role in its development. A family history of astigmatism increases the likelihood of developing the condition, and its severity may also be influenced by genetic factors.
6. Pregnancy:
Hormonal changes during pregnancy can sometimes cause temporary changes in vision, potentially including a slight increase or decrease in astigmatism. These changes usually revert after childbirth.
Can Eye Strain Cause Astigmatism to Get Worse?
No, eye strain itself does not cause astigmatism to get worse. Eye strain can cause symptoms like headaches, blurred vision, and fatigue, but it doesn't alter the underlying shape of the eye. While eye strain can exacerbate existing vision problems, it's not a direct cause of astigmatism progression. If you're experiencing eye strain, it's important to address the root cause, which might include needing an updated prescription for glasses or contact lenses.
How Often Should I Get My Eyes Checked for Astigmatism?
Regular eye exams are essential for monitoring astigmatism and other eye health issues. The frequency of check-ups depends on several factors, including age and the presence of other medical conditions. Generally, children should have their eyes examined regularly during their developmental years. Adults should have comprehensive eye exams at least every two years, or more frequently if recommended by their eye doctor.
What are the Treatment Options for Astigmatism?
Treatment for astigmatism focuses on correcting blurry vision. The most common treatment options include:
- Eyeglasses: Prescription eyeglasses with cylindrical lenses counteract the irregular curvature of the cornea.
- Contact lenses: Contact lenses, especially toric lenses, provide sharp vision by conforming to the eye's surface.
- Refractive surgery: Procedures like LASIK or PRK can permanently reshape the cornea to correct astigmatism.
This information is for general knowledge and does not constitute medical advice. Always consult with an ophthalmologist or optometrist for diagnosis, treatment, and management of astigmatism. Regular eye exams are crucial for maintaining good vision health and addressing any changes in refractive error.
