I read a lot, especially at night, on my Nexus 7 tablet, so eye strain and fatigue is always a concern for me. I’ve found ways around this to a large extent by enabling sepia tone mode in Google Play Books but it only goes so far. Google seems to agree and with the latest update to the eBook reader app, they have created a Night Light mode. Using information based on the amount of sunlight available, the app will gradually change the temperature and brightness based on that information.
When turned on, Night Light gradually filters blue light from your screen, replacing it with a warm, amber light as the sun sets. Night Light automatically adapts to the amount of natural sunlight outside based on the time of day, giving you just the right temperature and brightness. The color adjustment is more comfortable on your eyes and greatly improves low-light night reading.
Essentially, if you have been using the Sepia mode like I have in Google Play Books, this is an automatic version of making this change plus it adjusts the brightness. It is a bit genius.
Google Play Books Night Light Mode Is Easy to Enable
In the latest update to the app, enabling the new Night Light mode is done when you open up a book. At that point you will see a pop-up to enable the feature if you want to do so. Turn it on and
the automatic adjusting of temperature and brightness beings without you having to think about it again.
The new mode comes in the latest build of the Play Books app for both Android and iOS. That updated app is hitting their respective stores now and you should see it available over the course of the next few days. If you have the app already installed then you will see an OTA update for it shortly.
