The blue light from your phone has been studied countless times and these studies have proven that it makes you more alert when you look at it.

Naturally, this is not a good thing when it comes to trying to get to sleep. So does a blue light dimmer actually work? Well, at the moment, researchers cannot say that getting rid of a phone’s blue light or dimming it is less disruptive for your sleep. More subjects need to be studied and those who research need to observe them over more consecutive nights. Additionally, depending on the duration and intensity of exposure, green light can have a larger effect on alertness than blue. That determination must also be examined more closely before we can determine if blue light dimmers really work.
