The convenience of reading a book on a device is gaining in popularity, but one major problem is the unpleasant bright light from a screen — now, Google Play is introducing a new filtering feature that could change how you read books.

Google has just released a new update to the Google Play Books app that will make reading books on your device easier on your eyes, according to a Tech Times report.

Now, you won’t need to fiddle with the brightness of your screen or give up and go read a regular book — the 37.45 update will automatically adjust the light so you don’t need to squint while you read or have that tired feeling in your eyes from reading on a bright screen.

In an announcement to the official Google blog on Tuesday, senior product manager Greg Hartrell said the update would be available for users on Android and iOS platforms. Known as “Night Light, it will automatically adapt to the light coming from the screen “to the amount of natural sunlight outside based on the time of day, giving you just the right temperature and brightness,” Hartrell said.

How does it work? The app filters out the blue light that electronic devices emit, which is a major cause of sleep interruption, especially when done before bed — a time most people like to read. Now, when a user turns on Night Light, the app will gradually replace the blue light of the phone with an amber color that feels more natural.

Google Play Books has found that reading activity is at its highest at night before bed, typically betwen 8 and 10 p.m. This is what gave them the idea to make some tweaks to the app to make it more friendly to users, allowing them to read their favorite novel but still get a good night’s sleep.
