Fibromyalgia is best known for widespread pain and extreme fatigue, but many people are surprised to learn that it can also affect vision. Blurred vision, eye strain, light sensitivity, and difficulty focusing are commonly reported symptoms, yet they’re rarely discussed or properly explained.
If you’ve noticed changes in your eyesight since developing fibromyalgia, you’re not imagining it. Here’s what’s really going on, why it happens, and what you can do to manage it.
How Fibromyalgia Can Affect Vision
Fibromyalgia impacts how the brain and nervous system process signals. This altered sensory processing doesn’t just affect pain, it can also interfere with how visual information is interpreted.
Common vision-related symptoms include:
- Blurry or fluctuating vision
- Difficulty focusing or refocusing
- Sensitivity to light (photophobia)
- Eye pain or pressure
- Eye strain, especially with screens or reading
- Visual fatigue that worsens during flares
These symptoms often come and go, and many people notice they intensify during fibromyalgia flare-ups.
Why Blurred Vision Happens in Fibromyalgia
1. Central Nervous System Sensitization
Fibromyalgia causes the brain to amplify sensory input. Just as pain signals are intensified, visual signals may also be misprocessed, leading to blurred or distorted vision even when the eyes themselves are healthy.
2. Chronic Fatigue and Eye Strain
Extreme fatigue can weaken the muscles responsible for focusing the eyes. When your body is exhausted, your eyes struggle to maintain clarity, especially during prolonged screen use or reading.
3. Dry Eyes and Reduced Tear Production
Many people with fibromyalgia experience dry eyes, which can cause irritation, burning, and blurry vision. This may be linked to autonomic nervous system dysfunction or overlapping conditions.
4. Medication Side Effects
Several medications commonly prescribed for fibromyalgia, such as antidepressants, muscle relaxants, or nerve-targeting drugs, list blurred vision or dry eyes as potential side effects.
5. Migraines and Headaches
Migraines are common in fibromyalgia and can cause temporary visual disturbances, including blurriness, light sensitivity, or visual “auras.”
When to Be Concerned
While blurred vision can be a fibromyalgia symptom, it’s important not to ignore sudden or severe changes.
Seek medical attention if you experience:
- Sudden vision loss
- Double vision
- Severe eye pain
- Vision changes affecting only one eye
- Symptoms that worsen rapidly
These could indicate another condition that requires prompt evaluation.
How to Manage Blurred Vision with Fibromyalgia
Although there’s no single cure, many people find relief by combining medical care with practical lifestyle adjustments.
✔ Get Regular Eye Exams
An eye exam can rule out unrelated vision conditions and ensure your prescription is up to date.
✔ Manage Dry Eyes
- Use preservative-free artificial tears
- Take breaks during screen time
- Use a humidifier indoors
✔ Reduce Screen Strain
- Follow the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds)
- Adjust screen brightness and contrast
- Use blue-light filters or glasses
✔ Address Fatigue and Flares
Vision issues often worsen during flares. Managing sleep, pacing activities, and reducing stress can indirectly improve visual symptoms.
✔ Review Medications
If blurred vision started after a new medication, talk to your doctor about possible alternatives or dosage adjustments.
Living with Fibromyalgia-Related Vision Changes
Blurred vision can be frustrating, especially when it interferes with reading, driving, or working. The most important thing to remember is that this symptom is real, common, and experienced by many people with fibromyalgia.
Tracking when symptoms occur, identifying flare triggers, and advocating for yourself during medical appointments can make a significant difference.
Final Thoughts
Fibromyalgia doesn’t just affect muscles, it affects the entire sensory system, including vision. While blurred vision can be unsettling, understanding why it happens empowers you to manage it more effectively.
If you’re experiencing visual symptoms, you’re not alone, and you deserve answers, support, and care that takes every symptom seriously.
