How to adjust Blue Light filter and brightness right from the notification bar

This modern age has led to a tremendous increase in our use of smart devices. Growing users are having problems with eye strain as they spend long hours staring into their screens. Smartphones emit blue light on your screen to bring out the best quality of what you see but with its consistent exposure, it causes weariness to your eyes.

Many apps have come up with ways to reduce the brightness and exposure to blue light. A Blue light filter applies a filter to the screen which minimizes the blue light effect.

Let’s have a ‘brighter’ look on some of the apps that help reduce or alter the brightness, and how you can use them:

Using the Light Delight app

Step 1: Download and install the Light Delight app from Google Play. Once installed, open the app.

Step 2: Open the app and give it the required permissions to make changes to the display.

Step 3: Open the notification panel. You can increase/decrease the brightness by tapping the High/Low icon, but the notification bar remains to default brightness.

Step 4: Adjust the following settings – filter opacity, filter brightness, and color and check if they suit your vision.

Using the Brightness Control and Dimmer app

Step 1: Download and install the Brightness Control and Dimmer app from Google. Once installed, open the app. Step 2: Allow the app permission to display over other apps by switching the toggle adjacent to ‘Allow display over other apps’.

Step 3: Click on the app icon from the app drawer or your home screen. A pop-up window will show up that will allow you to change the brightness settings.

Step 4: Select ‘Icon’ or ‘Settings’ option from the pop-up window. This will enable the notification control from where you can change the brightness easily.

Step 5: Long Press on the app icon and select ‘Widgets’ to add widgets for brightness control. You can either add a single High/Low control widget or the one with specified control percentages.
