Dark mode (Dark Theme) is especially useful to reduce light intensity when using a phone at night. The latest Android 10 will now support a system-wide dark mode, meaning that most parts of the system can be turned into a dark theme.
If you want to turn on the Dark Theme on Android 10, check out the following guide!
1. Go to Android Settings and select Display & brightness.

2. Enable Dark theme.

3. The theme will be applied instantly.

You can turn on/off Dark Theme via the notification center. However, you may arrange the icon menu first before seeing the shortcut.

A darker screen color not only makes the viewing experience better but also reduce the power consumption as darker colors emit less luminosity than the brighter ones. Enabling a blue-light filter would also improve the convenience of the eyes further.
