Dark mode for ChatGPT and eye strain

Updated 2026-11-02

Quick answerChatGPT lets you pick a darker theme in settings, which helps long sessions. If side panels or code blocks still glare, a light page filter can soften the tab. This addresses screen comfort only, not headache diagnosis or treatment. Keep expectations modest.

ChatGPT theme

  1. Open settings from your profile menu.
  2. Choose a darker theme/appearance option.
  3. Reload the chat if the chrome stays light.

Browser overlay

  1. Use Migraine Mode if residual white panels bother you.
  2. Keep intensity low so Markdown stays readable.

Good to know

  • Product UI changes; verify the current Settings labels.
  • Native notes: /migraine-friendly/chatgpt/.

Session triggers

  • Long bright transcripts.
  • Syntax-highlighted code on pale backgrounds.
  • Streaming tokens redrawing the page.

FAQ

Does ChatGPT dark theme follow the OS?

It depends on the current product setting; set it explicitly if evenings feel worse.

Will a filter break copy-paste?

No. It only changes rendering in the tab.

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.
