You can activate Wind down mode to reduce eye strain before sleeping and prevent your sleep from being disturbed.

ㆍGreyscale : Displays colors on the screen as grey tones.

ㆍDo not disturb: Set the device to mute incoming calls and notification sounds, except for allowed exceptions.

CF.) Night mode (Settings > Display > Night mode) also can reduce eye strain by applying the dark theme when using the device at night or in a dark place.  However the dark theme may not be applied in some apps and Home/lock screen.
