How to Switch a Kindle to Night Settingsby Adam Brown
If you use an Amazon Kindle to read at night, you may find that the default screen settings are too bright, resulting in eye fatigue. Or perhaps your spouse is unable to sleep due to the excessive light radiating from your device's screen. Although the Kindle does not have an official night mode, if you read with a Kindle Fire you can change the display color mode to white on black (white text with a black background), reducing the amount of light from the screen.
Tap "Books" from the home screen.
Locate the book you want to read and tap it to open.
Tap the screen to pull up the Options toolbar and tap the "Text" button.
Select the "Font Style" tab and select the white on black text option from the Color Mode row.
- Magazines and some children's books with heavy illustrations cannot be read in the white on black color mode.
