Free Bluelight Filter protects your eyes against the harmful bluelight, which your smartphone permanently produces.
Modern displays are using three color pixels (red, green and blue) to display colors. For displaying red on your screen,
only the red pixel glows, for displaying yellow, the red and green pixels are glowing, for displaying white all pixels glow
and so on. Studies occupy, that the blue light influences the human hormonal system and harms the eyes. This supports eye
irritation and insomnia. To work against this you have the option not to use your smartphone, wearing glasses which filter
the bluelight or you can install the Free Bluelight Filter App.
Free Bluelight Filter provides a yellow filter which reduces the glowing of the blue pixels. Your eyes will be happy about this!
You can see how powerful the filter is, if you use your smartphone or tablet with the filter for a time and turn it suddenly off.
