À propos de l'application

Are you using your smartphone or tablet in the late evening?
Blue Light Filter may be an ideal solution for you!

What is Blue Light Filter?
An app that effectively reduces the amount of blue light emitted from electronic devices by overlaying a translucent filter.
Great for those who use their devices all day long and are feeling fatigued.
It keeps the eyes healthy and helps users achieve comfortable sleep.
Besides the blue light filter, the screen dim feature will reduce the screen brightness to a minimum level as night mode.

Why you should use Blue Light Filter?
Research shows that exposure to blue light imposes serious threats to retinal neurons, causes eye strain, and dry eyes, and inhibits the secretion of melatonin, a hormone that influences circadian rhythms. With our filter function, your vision health will be greatly improved.
It is recommended to turn on this app when you are reading or playing games, especially in a dark room.

Features:
● Reduce blue light
● Adjustable filter intensity (Auto/Manual)
● Adjustable color temperature
● Brightness setup
● Schedule
● Built-in screen dimmer
● Caffeine mode

Brightness setup
Fine tune the screen brightness including option to enable adaptive brightness

Schedule

Why Blue Light Filter uses AccessibilityServices API
Enabling this type of service expands the range of capabilities so screen filter can cover system views such as:
- Status bar
- Navigation bar
- Lock screen

And remove overlay limitations:
- Not allowing app installation

* Since Android 12, accessibility service is needed in order to enable a screen filter.

Enabling this won't allow Blue Light Filter to access your screen content
