Updated 2026-11-02

Quick answerOn a Chromebook, select the time at the bottom right, open Settings, then Device, Displays, and turn on Night Light. Adjust the color temperature and set a schedule: Sunset to sunrise or a custom time. Dark mode is in the wallpaper and style settings. These change the whole screen, not just websites.

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.
