Screen settings for photophobia (light sensitivity)

Updated 2026-11-02

Quick answerFor photophobia at a screen, lower display brightness, prefer darker page themes, reduce flicker and motion, and consider a soft green or rose tint. These are comfort steps with mixed evidence — not a diagnosis or a cure. Seek care for sudden vision change or severe light pain.
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.

Checklist

  1. Drop OS brightness until text is readable without squinting.
  2. Enable system and site dark themes.
  3. Turn off autoplay; reduce OS motion.
  4. Optional: Migraine Mode preset; tune intensity.
  5. Take breaks (/guides/20-20-20-screen-breaks/).

Good to know

  • Not medical advice. Migraine Mode is not a medical device.

What photophobia means here

  • Light feels painful, dazzling or worsens headache.
  • Common in migraine and after concussion; other causes exist — only a clinician diagnoses.

Levers and honesty

  • Lower brightness — often fastest comfort; PWM may bother some (limited evidence).
  • Dark UI — reduces bright fields; fatigue studies exist, migraine RCTs for app dark mode do not.
  • Soft green bias — narrow-band green experiments exist; screen tint is an unvalidated analogue.
  • Rose/FL-41-style tint — optical FL-41 literature ≠ CSS filters.

What we do not claim

  • No improvement percentages for the extension.
  • No replacement for prescribed FL-41 lenses.
  • Software cannot change real backlight PWM.

FAQ

Is photophobia the same as migraine?

No. Photophobia is light discomfort; migraine is one possible context among others.

Can an extension cure photophobia?

No. Filters change display light only.

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.
