About Night Eye
What is Night Eye?
Night Eye is a browser extension that enables dark mode on nearly any website and online PDFs automatically. Unlike simple color inverters, it analyzes each page’s colors and converts them to provide a smooth, consistent dark experience—no bright spots or flashes. Used daily by over 1,000,000 users.
What problem does it solve?
Staring at screens for 10-12 hours a day causes eye strain, headaches, and watery eyes. Night Eye reduces this by applying a comfortable dark mode across all websites you visit, with adjustable brightness, contrast, and blue light filtering for healthier late-night browsing.
Who is it for?
Ideal for anyone who spends long hours browsing the web—developers, students, designers, night workers—but also useful for users with light sensitivity or visual discomfort. It is not a system-wide dark mode for your operating system; it works exclusively inside your browser.
Real use cases
Use Night Eye to enable dark mode on Google Docs, Wikipedia, news sites, online forums, and any webpage. Customize individual websites or apply global settings. Power users can adjust color, brightness, contrast, and saturation per page, and even integrate with YouTube’s built-in dark theme.
