Bluelight Filter for Eye Care is a handy piece of software which allows you to apply a colored filter over the screen of your Android device in order to protect your eyes over the time. The user interface comes with a straightforward design and here you can configure aspects like the color of the filter and its opacity. The default value is set at 30%, but some users might not like this way because the screen gets very dark.
The more you increase this value, the darker the screen will get, but your eyes will get less and less tired. It's up to each individual to find the best balance that works for him. If you don't like tinkering with these settings, then you will be happy to hear that this tool also comes with an automatic mode. This feature will adjust the screen color based on external light to provide great protection for your eyes.
Moreover, you can schedule the application to remove the screen filter at a time defined by you inside the interface. Bluelight Filter can be set to launch the filter at the startup of your mobile device. Another plus for this app is that it runs on your smartphone or tablet without using many RAM and CPU resources.
