Blue Light Filter – Night Mode, Night Shift
Do you often read at night? Your eyes get tired and you can not sleep after long work with a smartphone? Blue Light Filter – Night Mode, Night Shift application is designed to solve this problem.
The reason for the high load on the eyes is a surplus of blue on the screen. The fact is that blue radiation in the visible spectrum (380-550 nm) violates the daily rhythms of a person.
Various studies have shown that the action of such rays has a bad effect on the retina of the eye, slowing down the production of melatonin by the body, which is responsible for circadian rhythms. It isn’t difficult to conclude that reducing the effect of blue radiation on the eyes will give a beneficial effect on human sleep.
The most important feature of the application is the built-in filters that regulate the color gamut of the screen and allow you to achieve a more natural image for the eyes. With one touch you can switch the screen mode to Night and reduce eye strain. This way you can read easily at night and it will not affect the productivity of your sleep.
The application carefully uses electricity, has a built-in adjuster to change the screen brightness and the amount of blue radiation.
It should be noted that the application must be paused before downloading other programs, as well as before taking a picture, otherwise, the output photo will be created taking into account the night effect of the application.

Night Shift OS 10
The Android application Night Shift OS 10 is very similar to the operating system of Apple and the corresponding function. On the one hand, this is good – the developer tried to make a complete copy of such an unusual opportunity, and on the other, because of this, the program interface doesn’t fit into Material Design style. But everything is extremely simple and clear.
The main advantages of Night Shift OS 10 over similar applications:
- Free change of the color temperature filter;
- Quick access to the application and the ability to enable/disable the one-click filter through the notification panel;
- It’s possible to enable and disable application notifications;
- Schedule for automatic on and off filter;
- Beautiful application interface;
- Without advertising.
Right on the main screen of the program, we have four parameters: turning on the filter, turning on the notification to quickly turn on the filter and access the application, color temperature configurator, setting the schedule.
The configurator of the color, or rather the filter, allows you to adjust the RGB color gamut and dimming parameters. By default, Night Shift OS 10 has its own settings, but it’s better to correct them yourself, since all phones have different types of matrixes, and everyone has a different vision.
The main condition for the adjustment – do not overdo it with blue, otherwise, the effect will be reduced to zero. According to the schedule, you can set the exact time for switching on and off the Night Shift OS 10 filter.
In general, Night Shift OS 10 does an excellent job, and most importantly, everything in the program is extremely simple and without advertising.

Dimly
As the experience shows, small programs are very thoughtful and are in fairly high demand. The same can be said about the Dimly application, which has been downloaded more than a million times from an official source only. What are its advantages?
Dimly Key Features:
- Dimming the display;
- Filtering blue light;
- Timer for automatic mode;
- Setting the minimum and maximum brightness levels;
- Shake to restore brightness to proper level;
- Automatic stop application;
- Simple user interface designed for ease of use.
After launching the Dimly utility, a small menu opens on the screen with key functions, including the following parameters: adjusting the brightness level, turning on the Blue light filter, turning off the program, and switching to application settings. As you can see, all the key features of the program fit on one screen, and even in such a miniature window.
Unfortunately, the program doesn’t allow to adjust the screen shade. It has only the standard shade options, but this is more than enough for comfortable use of the gadget.
So, we can set the minimum and maximum screen brightness levels. To return the screen brightness to a normal level (maximum brightness) you need only to shake the device. There are several levels of shake sensitivity.

Darker (Screen Filter)
Even tiny programs can be as useful as possible and not at all inferior to analogs in their functionality. A striking example is a utility with the unpretentious name Darker.
Advantages of the Darker app:
- Start Darker when the device boots;
- The automatic turn-on of the program on a schedule;
- The lower level of brightness is 20% lower than the standard;
- Custom color filter;
- Customizable buttons in the notification panel.
There is an interesting function “keep status bar brightness”. This option allows you to save the standard color gamut for the status bar. Most likely, this is done to improve the readability of notifications and a number of other useful information.
And now – about the main drawback of the Darker utility. Its developer has made almost all features paid. We can not change even the color temperature in the free version. With each such action, we will see a list of Darker Pro advantages and an offer to purchase the program.
The free version of Darker has several interesting features: setting priority to notifications from the application, automatically turning off the application in bright light. As a result, this program can analyze the lighting around us and fine-tune the screen settings for it.
On the one hand, Darker is a small, convenient and functional program for working with the color scheme of the screen and a number of other parameters. On the other hand, it has one obvious drawback, which is that the free version is unsuitable for use due to the lack of an automatic activation feature and a schedule.

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.
Conclusion
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.
