Blue Light Filter

Warm amber overlay blocks blue light & reduces eye strain. Adjustable intensity, warmth & auto-schedule. Better sleep starts here.

**Protect your eyes. Sleep better. Browse comfortably.** Blue Light Filter adds a smooth, warm amber overlay to every webpage you visit — reducing the harsh blue light emitted by your screen and helping your eyes feel relaxed no matter how long you browse. Modern screens blast blue light at your eyes all day. By evening, that exposure suppresses melatonin production, strains your eyes, and leaves you wired when you should be winding down. Blue Light Filter fixes that with a single click. --- **HOW IT WORKS** Blue Light Filter places a translucent warm-colored overlay on top of every webpage. Unlike dark mode extensions that invert colors or rewrite CSS, this approach is universal — it works on every site without breaking layouts, images, or videos. You're simply adding a warm tint over your screen, the same way physical blue-light-blocking glasses work. The amber-to-orange color range is tuned specifically for maximum blue light reduction with minimum color distortion. Your content still looks natural — just easier on the eyes. --- **PERFECT FOR** - Late-night browsing and working after sunset - Anyone who spends 4+ hours per day in front of a screen - Reducing digital eye strain, headaches, and eye fatigue - Improving sleep quality by reducing melatonin-disrupting blue light - Protecting eyes during long coding, reading, or streaming sessions --- **KEY FEATURES** - **One-Click Toggle** — Enable or disable the filter instantly from the toolbar popup. No setup required. - **Adjustable Intensity** — Dial the filter strength from 0% to 100% to find your perfect level of protection. - **Warm Color Tuning** — Slide the warmth control from soft amber (#FF9329) to deep orange-red (#FF5500) to match your preference and the time of day. - **Auto-Schedule** — Set a custom start and end time (e.g., 8:00 PM to 7:00 AM) and the filter activates and deactivates automatically — even overnight schedules work correctly. - **Works Everywhere** — The overlay is injected at page load, before content renders, so there's no flash of harsh light. Works on all websites including SPAs and dynamically loaded pages. - **SPA Navigation Support** — URL change detection re-applies your settings automatically on single-page apps like Twitter, YouTube, Gmail, and Google Docs. - **Zero Performance Impact** — A single lightweight `div` overlay using CSS `pointer-events: none` — completely invisible to your clicks and scrolls. - **100% Private** — No accounts, no servers, no tracking. All settings saved locally via `chrome.storage.local`. --- **PRIVACY** Blue Light Filter is 100% local. It requests no personal information, collects no analytics, and never contacts any external server. Your settings stay on your device, period.
