Make Reading iBooks in the Dark Easier for the Eyes with Auto-Night Mode on iPhone & iPad
If you use iBooks and your iPhone, iPad, or iPod touch to read, you can improve your evening reading experience by switching the theme to Sepia or the “Night” color scheme. Up until now though, you’ve had to perform that theme change yourself, and if you get caught up in a good book, you know it’s easy to get sucked into the book only to later realize that your eyes are perhaps overly strained due to the glaring white background and bright screen of the iOS device you’re reading on.
