My eyes tho

You can get an app to lower the screen brightness more.

turn on blue light filter, it makes it so much better at night

i use an app called twilight it is perfect for lowering the brightness below the usual lowest setting it is also a blue light filter it has timer settings so you can set it to automatically turn on and off at specific times

Get a privacy screen for your phone it reduces the brightness by another 30% or so permenantly

You can lower it in settings! Go settings-general-accessability-display accomodations. Then just reduce the white point till it’s dark enough. Have a wonderful day
