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.
