If you suffer from migraines, you may be all too familiar with the eye-related symptoms that often come with them—flashes of light, blurred vision, sensitivity to brightness, or even temporary visual loss. But how do you know whether your symptoms are part of a migraine or a sign of an underlying eye condition? Understanding the connection between migraines and vision can help you know when to manage symptoms at home and when to seek professional eye care.
How Migraines Affect Your Vision
Many migraine sufferers experience what’s called a visual aura—a temporary disturbance that affects both eyes and typically appears before or during a migraine. Auras may last for 20 to 60 minutes and can include:
- Flashes of light
- Zigzag patterns or shimmering lines
- Blind spots (scotomas)
- Distorted or blurry vision
- Tunnel vision
These visual changes are usually harmless but can be alarming, especially if you’re experiencing them for the first time. Auras occur due to changes in brain activity and blood flow that temporarily affect the visual processing areas.
Other Migraine-Related Eye Symptoms
Even without aura, many people experience eye symptoms during or after a migraine:
- Eye pain or pressure, especially behind the eyes
- Light sensitivity (photophobia)
- Tearing or redness
- Temporary blurred vision
- Difficulty focusing on screens or reading
These symptoms are generally short-lived and tend to resolve once the migraine subsides. However, repeated episodes can lead to eye fatigue and affect day-to-day activities like working, driving, or using digital devices.
What Is an Ocular Migraine
An ocular migraine is a rare condition where visual changes occur in just one eye and may or may not be followed by a headache. Unlike a visual aura that affects both eyes, ocular migraines are isolated to one eye and may involve:
- Temporary vision loss or dimming
- Flickering or blank spots
- Distorted vision
If you experience vision loss in one eye, even if it resolves quickly, you should seek medical attention. It could be related to an ocular migraine, but it may also signal a more serious issue like a retinal tear, optic nerve inflammation, or a vascular problem.
When Eye Symptoms Might Not Be Migraine-Related
Not all vision disturbances are caused by migraines. You should consult an optometrist or ophthalmologist if you experience:
- Ongoing blurred vision between headaches
- Double vision
- Eye pain with movement
- Flashes or floaters that increase suddenly
- Blind spots that don’t resolve within an hour
- Visual disturbances affecting only one eye
These symptoms could indicate other issues such as glaucoma, retinal detachment, optic neuritis, or dry eye disease—all of which require professional diagnosis and care.
How an Eye Exam Can Help
If you suffer from migraines with visual symptoms, a comprehensive eye exam can help rule out other conditions that may be contributing to your discomfort. At Louie Eyecare Centre, we use advanced imaging tools like OCT scans and retinal photography to evaluate the health of your optic nerve, retina, and blood vessels.
We also assess for other contributing factors such as digital eye strain, unaddressed refractive errors, or dry eye syndrome, all of which can worsen migraine-related symptoms or mimic them.
When to Talk to an Optometrist
If you regularly experience:
- Migraines with eye-related symptoms
- Changes in your usual migraine pattern
- New or worsening visual disturbances
…it’s time to get your eyes checked. Even if migraines are the underlying cause, addressing any additional eye strain or dryness can significantly improve your comfort and reduce the frequency or severity of episodes.
