Software for eye protection, health and productivity
Iris is the popular software for eye protection, health and productivity.
This Iris mini is totally free and super minimalistic.
You only have 1 button to Start and Pause the application. I find this super cool and other screen filter apps are too bloated for me.
This version for Android works with Screen overlay and it lowers your screen blue light and brightness for better sleep and less eye pain automatically when it's working.
