Understanding Migraine & Visual Symptoms
A migraine aura typically starts as a small flickering spot that expands across the vision in both eyes and then fades within an hour, often followed by a headache (though aura can occur without headache). Symptoms confined to one eye, or that are new after age 50, need careful evaluation because other conditions can mimic migraine.
Common symptoms
- Zigzag or shimmering lines
- Flashing lights
- Temporary blind spots
- Light sensitivity
When to seek care right away
Sudden vision loss, a first-ever aura after age 50, or visual changes with weakness, numbness, or trouble speaking need emergency care.

Frequently asked questions
How can I tell a migraine aura from a retinal problem?
Migraine aura usually affects both eyes' field of vision, moves or expands, and resolves within an hour. Flashes with new floaters, or symptoms in only one eye, should be examined promptly.
