Font color settings, I like in
window -> preferences -> General -> Appearance -> Colors and Font -> Basic -> Text Font
In this way, it should be all (JAVA and Android, etc.) modified.
Eye protection color settings:
window -> preferences -> General -> Editors -> Text Editors -> Background color
Tick off System Default, click 'color', pop up the color selection panel, choose your favorite color
Background color recommended to you: Hue: 85. Saturation: 1 2 3. Brightness: 2 0 5
