Why should we care about blue light?
Blue light is part of visible light spectrum that we are exposed to it by the sun every day. However, nighttime exposure to the light at high levels by smartphones, tablets, laptops, and other LED screens may impair your vision.
It also suppresses the production of hormone melatonin, which hinders your body's natural sleep cues.
When your melatonin level and sleep cycle are disrupted, your risk of a wide range of ailments, from depression to cancer, may go up.
You can get help by using apps that limit the amount of blue light coming from our screens.
When trying to download other apps you need from other than Google Play Store, sometimes they are not installed properly with the bluelight filter is activated. In such case, please turn off the bluelight filter for a moment and install other applications.
Battery consumption is low when the filter is applied, due to low total CPU usage except for low CPU usage.
