Why flickering light bothers people with migraine
Flicker photophobia as an experience of inefficient coding
This project looks at how people with migraine and light sensitivity experience flickering light and whether their everyday light exposure and brain responses differ from people without migraine.

What this research studies
If I have migraine and feel bothered by flickering light, this work will compare my real-world light exposure (measured with wearable light loggers) to people without migraine. I may be invited to do behavioral tests that measure how different flicker patterns feel and how much discomfort they cause. The team will also record brain responses to flicker to see whether people with migraine process flicker differently. The goal is to link the properties of the visual environment, perception, and neural signals to why flicker feels uncomfortable.
Who could benefit from this research
Good fit: Adults who experience migraine with bothersome sensitivity to flickering or changing light would be the best candidates for participation.
Not a fit: People without migraine or whose light sensitivity is due to a separate eye disease rather than migraine-related photophobia may not benefit from this work.
Why it matters
Potential benefit: If successful, this research could point to clearer reasons why flicker triggers discomfort and help guide personalized light recommendations or interventions to reduce symptoms.
How similar studies have performed: Prior lab research shows efficient-coding ideas can explain sensory judgments, but applying this framework specifically to migraine-related flicker sensitivity is a novel direction.
