Blue Light Filter
Free Chrome extension that applies a warm amber overlay to reduce blue light. Protect your eyes at night. Adjustable intensity and scheduling.
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. Dial the intensity from 0% to 100%, tune the warmth from soft amber to deep orange-red, and set an overnight schedule so the filter switches on and off automatically. Zero accounts. Zero tracking. Just comfortable browsing.
