How to use the warm light on your Kindle for comfortable reading at night

All recently released Kindle e-readers come with a built-in headlight, which you can activate when reading at night or in the dark. If you like to read at bedtime, the blue light emitted by the white front light may disrupt your sleep or cause eyestrain.

Fortunately, some Kindle models come equipped with a warm light that adds a nice yellow-orange tint to the screen for a comfortable reading experience. Similar to your phone’s night mode, the feature reduces harsh blue light. Here’s how to activate it.

Which Kindle e-readers support warm lighting?

Unfortunately, Kindle models only support warm light.
