Blue Light Filter

**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.
