Just had a migraine —
or something frightening in your vision?

A visual aura is a temporary change in how your brain processes vision.

You might notice flashing lights, shimmering patterns, zigzag lines, blind spots, or a small bright area that slowly changes shape. Although it can feel frightening, a visual aura usually goes away on its own within an hour.

The first time it happens can be overwhelming. Many people think they’re losing their eyesight. The good news is that, for many migraine sufferers, the eyes themselves are healthy — the changes come from the brain’s visual system.

Most visual auras last between 5 and 60 minutes.

Many people notice that the aura starts as a small visual disturbance, gradually changes or expands, and then disappears completely.

If your visual symptoms are new, unusually prolonged, or different from your typical pattern, it’s important to seek medical evaluation.

This is probably one of the first questions almost everyone asks after experiencing a visual aura.

The good news is that a typical migraine aura does not damage your eyes or make you go blind. The visual changes come from temporary changes in how the brain processes vision — not from permanent injury to your eyes.

Even though the experience can feel overwhelming, your vision usually returns to normal after the aura ends.

However, sudden vision loss in one eye or persistent vision changes should always be evaluated by a healthcare professional.

No. Although they can seem similar at first, they’re actually very different.

Floaters are tiny shadows inside the eye. They often look like small dots, strings, or cobwebs that drift when you move your eyes.

A visual aura comes from the brain. It usually develops gradually, may shimmer or expand over several minutes, and then fades away completely.

If you’re unsure which you’re experiencing, an eye examination can help rule out eye conditions while your healthcare provider evaluates possible migraine.

Stress doesn’t cause migraine by itself, but it can lower your brain’s threshold and make an attack more likely.

Many people notice that migraines appear during stressful periods — or even after the stressful event has passed, when the body begins to relax.

Many people expect to feel completely normal once the headache is over — but that’s not always what happens.

The hours or even days after a migraine are called the postdrome, sometimes nicknamed the “migraine hangover.”

During this time, you might notice:

• Feeling tired
• Difficulty concentrating
• Light sensitivity
• Mild dizziness
• Emotional ups and downs
• A sense that your brain is “not quite back to normal”

This recovery phase is common and usually improves gradually with rest, hydration, regular meals, and good sleep. Be patient with yourself. Your brain has just worked very hard, and recovery takes time.

First… take a slow breath. As frightening as an aura can feel, it is often temporary.

If possible:

• Move to a calm, comfortable place.
• Reduce bright lights and screen time.
• Drink some water if you’re able.
• Practice slow, gentle breathing.
• Allow yourself to rest until your vision returns to normal.
• Follow your healthcare provider’s treatment plan if you have one.

If this is your first aura, or if your symptoms include sudden weakness, difficulty speaking, severe vision loss, or a sudden severe headache unlike anything you’ve experienced before, seek immediate medical care.

Many people ask this after their first few migraine attacks.

The answer is: there is every reason to hope. While migraine may remain part of your life, many people learn to recognize their triggers, reduce the frequency of attacks, and regain confidence.

Life may not look exactly the same, but it can still be full, meaningful, and joyful.
