How to reduce blue light for migraine (with limits)

Updated 2026-11-02

Quick answerUse Night Light or Night Shift, warmer display modes and an optional amber tint to cut short-wavelength light at night. Evidence that blue-light filters prevent migraine is limited; comfort varies. Pair with lower brightness and less flicker rather than chasing zero blue.
Not medical advice. Migraine Mode is a screen-comfort tool, not a medical device. It does not diagnose or treat disease. When to see a doctor.

OS warmth

  1. Windows: Settings → System → Display → Night light.
  2. macOS: System Settings → Displays → Night Shift.

Browser

  1. Site dark themes.
  2. Optional warmer Migraine Mode preset at modest intensity.

Reality checks

  1. Software ≠ optical blue-blocking glasses.
  2. Address PWM flicker separately.

Evidence in one line

  • Photophobia pathways are broader than blue alone (Noseda 2016).

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.
