We spend most of our time browsing social media feeds or watching YouTube videos on our smartphones. Smartphones or any display emit light that plays a very important role in activating our biological clock. Usually, we feel energetic when there is more light, so looking at the smartphone screen for long hours can make it harder to fall asleep. Modern smartphones have a feature called “Blue Light Filter” that blocks blue light from the screen to reduce eye strain. In this article, we’ll look at how you can program a blue light filter on Android.

Program a blue light filter on your OnePlus

If you have a OnePlus Android device, you can easily program a blue light filter. In particular, the blue light filter on OnePlus phones is called “Vision Comfort.” The main function of this feature is to help you prevent the blue light on the phone screen from entering your eyes to reduce fatigue.

This allows you to program a blue light filter on your Android OnePlus.

1. Open the Settings menu by dragging the notification shadow down and tapping the “Gear” icon, or by opening the application box and selecting the “Settings” menu icon.

2. Press “Display”. In the View menu you will find the option Vision comfort.

3. In the “Vision Comfort” menu, press the “Activate automatically” option and select the “Custom interval” option. It allows you to select a custom time period for the automatic activation of the blue light filter.

4. You can also change the color temperature and saturation level of the blue light filter from the “Vision Comfort” menu.

That’s it! The blue light filter is now set on your OnePlus Android phone and will start automatically on schedule.

Program a blue light filter on your Samsung Android phone

For you who own a Samsung Galaxy, the blue light filter option is called “Eye Comfort Shield.” Fortunately, you can also program it to start automatically.

1. Go to the Galaxy Settings menu and select the View option.

2. From the View menu, find Eye Eye Shield. On some Galaxy phones, the blue light filter is simply called “Blue Light Filter” or “Night Shift.”

3. When you open the “Eye Shield” menu, you will see several options that you can edit and modify. One is the “Set Schedule” option, which allows you to choose between an automatic sunset and sunrise interval or a custom schedule.

4. If you use the “from sunset to sunrise” option, location services must be turned on. This notifies your phone when the sun rises and sets your position.

5. Setting a custom schedule will automatically turn the blue light filter on and off according to the time period set for your Android phone.

Other Android phones

If you’re using a fairly new Android phone, the blue light filter option should be built, albeit under a different name. Most of the time, its option can be found in the Display section of the Settings section.


If you use the phone intensively throughout the day, you need to program the blue light filter to turn on at night so that the bright screen does not affect sleep. To view your content on a larger screen, stream your Android screen to your TV.
