Is dark mode better for migraine? What studies on visual fatigue show

Updated 2026-11-02

Quick answerEvidence on dark mode is mixed and none of it was tested during migraine attacks. Studies found less visual fatigue with dark mode in bright rooms and at night, no difference in dim rooms in one smartphone study, and no significant difference in a 2025 tablet trial. Use it if it feels better.

Studies

  • IEEE Access 2021: at night, dark mode reduced objective fatigue; higher text contrast was better.
  • IJHCI 2024: lower fatigue in dark mode at 450 lx and 3 lx.
  • ACHI 2024: dark mode helped in bright, not dim, light.
  • Tablet trial 2025: no significant difference in visual fatigue.

How Migraine Mode handles it

  • Smart dark mode inverts bright pages but leaves already-dark sites and photos alone.
  • You can switch it off and keep only dimming and tint.

FAQ

Does dark mode reduce eye strain?

Sometimes. Results depend on room light; several studies favor dark mode in bright rooms or at night, others find no difference.

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.
