What is Night Light and how does it work?
Night Light is a feature that adjusts the color temperature of your screen to reduce eye strain and help you sleep better. It works by filtering out the blue light emitted by your device’s screen, which can suppress the production of melatonin, the hormone that regulates sleep. When Night Light is enabled, your screen will take on a warmer, more yellowish tone, which is easier on the eyes and can help you relax before bed. This feature is especially useful for people who use their devices in the evening or at night, as it can help reduce the negative effects of screen time on sleep.
The Night Light feature is usually built into the operating system of your device, and it can be scheduled to turn on and off automatically at certain times of the day. For example, you can set Night Light to turn on at sunset and turn off at sunrise, so you don’t have to worry about adjusting it manually. Some devices also allow you to adjust the color temperature and brightness of Night Light to your liking, so you can customize it to suit your preferences. Overall, Night Light is a useful feature that can help you use your device more comfortably and promote better sleep habits.
