It isn’t difficult to conclude that reducing the effect of blue radiation on the eyes will give a beneficial effect on human sleep.

Night Shift OS 10

Night Shift OS 10Night Shift OS 10The Android application Night Shift OS 10 is very similar to the operating system of Apple and the corresponding function.

The configurator of the color, or rather the filter, allows you to adjust the RGB color gamut and dimming parameters.

Scientists have confirmed the negative impact of blue light…

Scientific studies have confirmed the interrelation between the brightness and color of the phone screen with the activity of the human nervous system. Fixing your gaze on the blue screen before bedtime, you can knock down a well-functioning mechanism that regulates the change of day and night in your brain. This will cause insomnia and non-sleep.

It’s all about the special pigments of the eye – melanopsins, located in the eye, skin, and brain. Due to the special sensitivity, they perceive the blue color at a wavelength of 460-480 nm. Melanopsin is involved in the synthesis of melatonin – the hormone of sleep and awakening. The study involved the average smartphone users who regularly read from the screen before going to bed. In such cases, sleep was delayed for an hour.


Each application from our digest copes with its main task – filtering blue light. Somewhere there is advertising and many functions, somewhere the other way around, and somewhere there is a good user interface with all the above advantages. Choose what is easier and more convenient for you, and always protect your eyes and sleep from harmful rays.
