Blue light is a harmful type of light that is most often seen in digital screens. When you regularly use devices such as smartphones and computers, this blue light can potentially cause both immediate and long-term damage to your eyes. Additionally, research shows that blue light can affect sleep patterns. The blue light that’s emitted from those screens can delay the release of sleep-inducing melatonin, increase alertness and reset the body’s internal clock to a later schedule.
Luckily, Windows 10 has a feature that can filter the amount of blue light coming from your screen and make your display use warmer colors at night to help you sleep better and reduce eyestrain. This feature can be found in your settings menu. If you find yourself working after hours or in low light conditions, you can turn this feature on by:
Go to Settings > System > Display. Set the “Night light” feature here to “On” to enable it, or “Off” to disable it. If you don’t see the Night light option, you may have to check for Windows updates.
The initial impression of the yellow hue might be weird at first, however, your eyes will ease into the change. Once you get used to the hue, you should experience a significant difference in your eye strain.
