Any time is a good time to read, but at night is perhaps the best. What better way to drift off to sleep than with a great book? Our readers agree. Looking at reading time across the world, we see that activity peaks between 8:00 pm and 10:00 pm local time. But we also know looking at a bright screen before bed can be hard on your eyes. Cue the announcement!
Today we’re introducing Night Light, a new feature that makes night time reading more enjoyable and easier on the eyes. 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.
