For all of us who work in front of a computer screen during the day, eyestrain is a constant issue. The blue light emitting from the screen produces eye fatigue at least and sometimes is responsible for more severe eye problems. Exposure to blue light at night may be more harmful to your health. Our circadian rhythm is based on light information we get from the sun. Blue nighttime light suppresses the secretion of melatonin, a hormone that influences our internal clock.

When you hit this option, then your microphone will be dead for all the calls you receive or make through Viber, Messenger and Skype.
For some unknown reason, your voice would not be heard by the other end of the line. This issue occurs only in voice over internet calls.
I suppose the system messes up the commands, because "Ok Google" has to be detected on any screen (including the one of the call) and at
the same time, the app is waiting for some vocal input to send.
This is an Android OS issue. I hope it will be resolved soon.
