When you're in bed reading a really compelling book, you don't always want to stop just because it's late and your spouse wants to go to sleep. That's when you need the low-light Night theme in iBooks. It means you can finish the chapter without the glare of the screen hurting your eyes or disturbing your partner. 

The coolest part about the Night theme is that you can set it to activate automatically when you're reading in a low-light situation. Using your device's ambient light sensors, the feature will automatically invert the colors on your screen when it's dark, making the screen black and the words white. To turn on Auto-Night Theme, tap on the font icon and toggle Auto-Night Theme on. Now if the ambient lighting changes, so will your display.

  

 

If you prefer to turn Auto-Night Theme on or off manually instead, make sure the feature is toggled off and tap Night whenever you wish to use the low-light reading feature.
