Night Eye Filter is a lightweight application that lets you easily adjust the brightness of your smartphone’s screen to prevent eye strain and other eye-related problems.

It comes with an in-built night mode that lets you use your device with ease, even in the dark. It also includes a filter that lets you easily change the color of the light emitted by your device, which can help you sleep better.

The application is designed to work on all smartphones that use Android, and is compatible with both mobile and tablet devices. It can also be used on desktops, but it is not recommended for use on laptop devices.
