Gaming with migraine: flashing, motion and display settings

Updated 2026-11-02

Quick answerGames often use flashing effects, fast camera motion and bright HDR highlights. WCAG treats more than three flashes per second as a seizure risk, and people with migraine are more sensitive to flicker. Many games offer options to reduce flashing, motion blur and camera shake. Lower brightness and turn off HDR on bad days.

What the research says

  • Kowacs 2005 and Coleston 1995: lower flicker-fusion thresholds in migraine.
  • Miller 2024: more headaches after flicker exposure in people with migraine.
  • Wurthmann 2021: increased motion sickness in vestibular migraine.

Settings

  • Turn on reduce flashing or photosensitivity options in the game.
  • Turn off motion blur and camera shake.
  • Lower brightness; turn off HDR if highlights hurt.

FAQ

Can games trigger migraine?

Flashing and motion can bother sensitive people; triggers vary.

Does Migraine Mode work in games?

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.
