I saw a lot of people tries to replace their phones with other digital devices, so the screen time doesn't reduce, just spread.
Instead I tried to do as much things as possible on devices without screen or without devices at all.
Some examples:
Internet radio app -> AM/FM radio
Audio player app -> speaker with inbuilt mp3 player
Games app -> board and cards games
Midi keyboard+virtual synth ->kalimba and electric piano
News app -> newspapers
eBooks -> audiobooks
Youtube -> download audio and listen instead of watching.
Different small things like alarm clock, torch, calculator -> stand alone devices instead of phone .
Pros: reduced eyesore and headache , phone's battery now lasts almost 3 days, I can actually spend time with partner and family members instead of constant watching on the phone.'s screen.
Cons: takes time to buy and setup everythin
