Bluelight Filter

Available at Google Play

- +

It’s a known fact that prolonged exposure to blue light emitted by electronic devices such as computers, tablets and smartphones can cause eye strain. This is particularly true when using the devices at night and it can adversely affect sleep. 

The Bluelight Filter app gives protection to users’ eyes while they are reading from websites or playing games on smartphones. Functioning as a light filter, this free app allows users to adjust their smartphone’s screen colour to reduce harmful blue light emission.

The application’s interface is simple. What users need to do is download the application to their phone, and then it will pop into the notification bar. Next, go to Settings menu to adjust the amount of opacity of the filter and then choose from five available colours: natural, yellow, red, brown and black. The app also allows users to automatically enable the filter when the phone starts up.
