Best Blue Light Filter Apps For Android Devices


Best Blue Light Filter Apps For Android: Nowadays many phones and PCs have a native blue light filter. It might be in the name of “Eye Care” or “Night Sight” but usefully they perform the same function. However, the customizations that native apps offer are quite limited. You can also change the color temperature or schedule a particular time for the function to work. These are pretty basic. But if you want more control like screen dimming or customizable color overlays, then you would need a third-party app. But before we proceed to the best blue light filter apps for Android firstly understand what’s blue light and the amount of damage it can cause to our eyes.

Also, It helps in maintaining circadian rhythm(natural clock) by defeating melatonin production and thus boosting our alertness.

As the sun sets our body requires to rest and sleep. This is where the blue light from the device creates a hindrance and besides signaling the body towards sleep. Also, it makes us alert and active. Long exposure can also cause potential retina damage and suppress melatonin creation when needed.

Red Moon

Red Moon is the least open-source app that doesn’t have many bells and whistles. The interface is quite minimal and you get a toggle switch to allow and disable the filter. Some basic sliders enable you to customize the color, opacity, and darkness of the filter. Except for this, you can also schedule the overlay based on the sun timings.

Red Moon is a free app on F-Droid whereas it is paid on the Google Play Store.

Red Moon applies an overlay on newly installed apps. However, In case if you want to disable it, there is a Pause in Excluded Apps” choice as well. But if you’re one of those who like to keep various filter options, Red Moon enables storing your custom configurations.

Unlike Red Moon, Blue Light provides limited control over the color temperature. Besides slider, you get presets like Night Shift (3200K), Dawn ( 2000K), Candlelight (1800K), Incandescent Lamp (2700K), Fluorescent Lamp (3400K), and Eclipse (500K).

Night Shift

It is unlikely that you can modify your blue light settings according to days of the week. But if you do, Night Shift is the best choice for you. It comes with some presets like bright, dark, medium, ultra-dark and no tint mode.  In some situations, if you want to modify these presets you have the choice to not only edit it. But just add custom presets as well. However, like the other two apps, you can select a color temperature palette and also tweak the intensity.

Let’s come to the scheduler, you can not just add a start and end time but also pick selective days at which the filter will be enabled. Also, the free version can handle most of the use cases.

Night Owl doesn’t do something additional. However, I put it on the list just because of the intuitive UI. Like the other apps, it has a Screen Dimmer option, blue light filter, scheduler, etc. But in case you want to change the RGB values of the filter you can then tweak that from the Advanced Filter SettingThe most amazing feature is Shake to sop which stops the dimming whenever you shake the phone.
