Is dark mode better for migraine?

Updated 2026-11-02

Quick answerDark mode often feels better during migraine-related light sensitivity because it removes large bright areas. Studies on visual fatigue support darker UIs in some settings, but they do not prove dark mode prevents migraine attacks. Use it as comfort alongside brightness and motion control.

FAQ

Should every site be dark?

If a dark theme breaks forms, pause it on that site.

Pure black or dark grey?

Personal; some prefer dark grey to reduce halo effects on OLED.

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.
