Chronic migraine and screens: daily-use settings with evidence
Updated 2026-11-02
Quick answerChronic migraine means headache on 15 or more days a month for more than three months, with migraine features on at least eight. With symptoms most days, screens need to be comfortable every day. A preliminary 2021 trial of green light lamps reduced headache days, but screen tints have not been tested.
What the research says
- ICHD-3 1.3 defines chronic migraine.
- Martin 2021: 29 patients used a green LED lamp 1–2 hours daily for 10 weeks; headache days fell; preliminary, one-way crossover design.
- Hoggan 2016: in chronic migraine, a 480 nm notch filter was no better than a sham filter.
Daily settings
- A schedule that turns on calm settings automatically.
- Room-matched dimming and a soft green tint.
- Regular breaks.
When to get help
- Chronic migraine has specific treatments; see a doctor or headache specialist.
- Using painkillers on many days can make headaches worse (NICE).
FAQ
Can screen settings treat chronic migraine?
No. They may make screens more comfortable; treatment needs a doctor.
What did the green light trial use?
A green LED lamp in a dark room, not a screen tint.

Not a medical device and not medical advice. Migraine Mode is a screen-comfort tool: it does not diagnose, treat, cure or prevent migraine or any other condition, and it does not replace a doctor. Its settings are based on studies of light, colour, flicker, patterns and motion; the extension itself has not been clinically tested. When to see a doctor.
