Universal Brightness

Universal Brightness lets you control how bright websites appear in your browser. Instantly dim any page to create a more comfortable viewing experience, especially in low-light environments or during long browsing sessions.

Many websites use bright colors and white backgrounds that can cause eye strain, headaches, and fatigue. This extension applies a smooth brightness reduction directly to web pages, helping you browse longer without discomfort—without changing your system display settings.

Universal Brightness works on all websites and updates in real time, giving you consistent control wherever you browse. Whether you are reading, working late, or simply prefer a darker screen, it makes the web easier on your eyes.
