Are your glasses or contacts not providing the sharp vision they once did? Are objects appearing increasingly blurry or distorted? Your astigmatism might be changing. Astigmatism occurs when your eye’s surface isn’t perfectly spherical, causing blurred vision. But it’s not static; it can evolve over time. This comprehensive guide delves into the reasons why your astigmatism might be worsening, from daily habits to underlying medical conditions. We’ll explore the science behind it and offer practical tips for maintaining optimal vision.
Astigmatism can indeed worsen over time. Understanding the reasons empowers you to take proactive steps to protect your vision. Let’s explore some key factors:
Keratoconus: A Changing Cornea
Keratoconus is a significant cause of worsening astigmatism. The cornea (the clear front part of your eye), normally dome-shaped, progressively thins and bulges outward, resembling a cone. This distortion increases astigmatism, causing straight lines to appear wavy or blurry and often increasing light sensitivity. Corneal topography, a 3D mapping procedure, aids in diagnosis. Treatments like corneal cross-linking (using eye drops and UV light to strengthen the cornea), specialized contact lenses, or, in severe cases, corneal transplants, can help manage keratoconus.
Cataract Surgery and Astigmatism
While cataract surgery effectively restores vision clouded by cataracts, it can sometimes influence pre-existing astigmatism. Removing the clouded lens and replacing it with an artificial one may subtly alter the cornea’s shape, affecting astigmatism. Modern techniques and advanced intraocular lenses (IOLs) minimize this risk. Corrective lenses or LASIK can often address any post-surgery astigmatism.
Aging Eyes
Aging brings changes to our eyes. Eyelid muscles may lose tone, and the eye’s lens can change shape, subtly influencing the cornea and potentially increasing astigmatism. Understanding these age-related shifts helps us adapt and seek appropriate vision correction.
Lifestyle Habits and Eye Health
Our daily habits can also play a role. Excessive screen time, squinting, and poor lighting strain eye muscles, potentially influencing the cornea over time. Habits like following the 20-20-20 rule (looking 20 feet away for 20 seconds every 20 minutes) and ensuring proper lighting can reduce eye strain.
Other Contributing Factors
Less common factors include eye injuries and certain medical conditions. Sudden vision changes should be promptly evaluated by an eye doctor.

Ongoing research continues to explore the complexities of astigmatism, and new treatments may emerge in the future. Discuss any vision concerns with your eye doctor for personalized advice.
Why Did My Astigmatism Suddenly Get Worse?
A sudden worsening of astigmatism, causing increased blurriness and distortion, can be concerning. Several factors might contribute to this. Let’s explore the possibilities:
Is It Aging?
As we age, eye structures, especially the cornea, can subtly change shape. This can influence how light enters the eye, potentially making existing astigmatism seem worse. This usually happens gradually, but if you haven’t had a recent eye exam, the change might seem sudden.
Recent Eye Injury?
Even minor injuries, like a bump or poke, can affect the cornea’s shape, potentially causing a sudden change in astigmatism. Seek immediate medical attention after any eye injury that affects your vision.
Could It Be Keratoconus?
Keratoconus progressively thins and bulges the cornea, significantly impacting astigmatism and causing worsening blurry, distorted vision. Early diagnosis is crucial.
Other Vision Problems?
Untreated vision problems like nearsightedness, farsightedness, or presbyopia can sometimes mask or exacerbate astigmatism. Correcting these underlying issues might improve your overall vision.
Overall Health Matters
Overall health can influence eye health. Uncontrolled diabetes, for example, can affect the eyes and potentially impact astigmatism. Managing chronic conditions is essential for maintaining good eye health.
Recent Eye Surgery?
While LASIK and cataract surgery generally improve vision, they can sometimes alter corneal shape, occasionally worsening pre-existing astigmatism or creating new astigmatism. Discuss potential risks and benefits with your eye doctor before any surgery.
Signs of Worsening Astigmatism
Increased blurriness, distorted vision, eye strain, difficulty with night vision, and increased squinting can suggest worsening astigmatism. A comprehensive eye exam provides a definitive assessment.
What to Expect at an Eye Exam
Eye doctors use various tests to assess astigmatism, including visual acuity tests (eye chart), keratometry (corneal curvature mapping), and refraction tests (lens prescription determination). Treatments can range from updated prescriptions to refractive surgeries like LASIK or PRK.

How Do You Stop Astigmatism from Worsening?
Let’s discuss how to manage astigmatism and potentially slow its progression.
Why Does Astigmatism Sometimes Worsen?
Astigmatism results from an irregularly shaped cornea, causing blurred vision. Several factors can contribute to this irregular shape worsening over time:
Keratoconus: This condition progressively thins and bulges the cornea.
Eye Injuries: Trauma can alter corneal structure.
Eye Surgery (rarely): Certain procedures can sometimes cause corneal changes.
Astigmatism often accompanies other refractive errors like nearsightedness or farsightedness. These, combined with natural age-related eye changes, can sometimes make astigmatism seem worse.
Managing Your Astigmatism
1. Regular Eye Exams: Like a car tune-up, regular eye exams allow your doctor to detect subtle corneal changes, adjust prescriptions, and check for conditions like keratoconus. Early diagnosis is key for effective management.
2. Lifestyle Adjustments:
Good Lighting: Reduce eye strain by ensuring adequate lighting, especially for close-up tasks.
The 20-20-20 Rule: Reduce eye strain by looking at something 20 feet away for 20 seconds every 20 minutes.
Ergonomic Workstation: Position your computer screen at eye level and arm’s length to minimize eye strain.
3. Corrective Options:
Eyeglasses and Contact Lenses: These correct how light bends into your eye. Toric contact lenses are specifically designed for astigmatism.
Refractive Surgery (LASIK): This can reshape the cornea, but it’s not a permanent fix and astigmatism may return. Discuss risks and benefits with your eye doctor.
The Emotional Side and Future of Astigmatism
Worsening vision can be frustrating. Talking to your eye doctor, joining support groups, and focusing on proactive management can help. Ongoing research offers hope for better treatments in the future. Stay informed about new developments and discuss them with your ophthalmologist.
What Should You Avoid If You Have Astigmatism?
Living with astigmatism requires understanding how to minimize its impact. While astigmatism itself may not drastically worsen due to lifestyle, certain habits can exacerbate symptoms.
Astigmatism: Understanding the Blur
Astigmatism occurs when the cornea or lens is irregularly shaped, like a football, causing blurred or distorted vision at all distances, along with potential headaches and eye strain. While lifestyle factors don’t directly cause worsening of the underlying condition, certain habits can intensify symptoms.
Minimizing Discomfort: Things to Avoid
Excessive Screen Time and Close-up Work: Prolonged screen use or close-up activities can greatly strain your eyes, making astigmatism symptoms more noticeable. The 20-20-20 rule is crucial here.
Dim Lighting: Straining to see in dim light worsens blur and eye strain. Ensure adequate lighting for all activities.
Rubbing Your Eyes: Rubbing irritates the cornea, potentially increasing discomfort and blur. Consult an eye doctor for persistent itchiness or dryness, which could indicate dry eye, allergies, or other conditions.
Proactive Steps for Better Vision
Corrective Lenses: Eyeglasses with cylindrical lenses and toric contact lenses are specifically designed to correct astigmatism. Discover how to wrap with kerlix, to ensure optimal bandaging for related conditions.
Regular Eye Exams: Crucial for monitoring astigmatism, adjusting prescriptions, and detecting other potential eye conditions early.
Healthy Lifestyle: A balanced diet, regular exercise, and sufficient sleep support overall eye health, indirectly benefiting astigmatism management. It is extremely beneficial for wearers of collars with owners number on it to have identification for peace of mind.
By understanding what to avoid and taking proactive steps, you can manage your astigmatism effectively. Consult your eye doctor for personalized advice. Ongoing research continuously generates new advancements in vision correction, so stay informed about the latest developments.
