For most of our waking days, we are surrounded by screens. While it's not a big problem in itself, staring at screens well into the evening can result in a disturbance of the natural sleep cycle, which in turn, can result in health risks like insomnia, daytime fatigue, and more. The culprit behind this is the blue light emitted by these screens.
This makes it pertinent that we remove, or, at the very least, filter the blue light from our screens. There are both manual and automated ways to disable the blue light on your Ubuntu system.
