How to Reduce Blue Light on Your Screen Without Installing Software

Not everyone wants to install system-level software like f.lux or Night Light just to reduce blue light. Maybe you're on a work computer where you can't install apps. Maybe you don't want software modifying your display at the system level. Maybe you just want something lighter.

Blue Light Filter runs entirely as a Chrome extension. No desktop app, no system modifications, no admin privileges required. It applies a warm overlay to your browser content, reducing the blue light emitted from web pages.

Since most people spend the majority of their screen time in a web browser, this covers the primary source of blue light exposure. Documents, social media, news sites, and email — all the bright white backgrounds that blast blue light — get filtered automatically.

The warmth level is adjustable from a barely-noticeable tint to a deep amber. Set it on a schedule and forget about it. Your browser gets warmer as the evening progresses, and returns to normal in the morning.

For people who want blue light reduction without the commitment of desktop software, a browser extension is the lightest possible solution.
