Windows 10 “Night Light”: Reduce your PC’s Blue Light Emission with this feature

Technically, all electronic devices, gadgets and appliances (smartphones, tablets, TVs, etc.) with a screen/display emits blue light — which has an adverse effect on your vision and the way you sleep. Reducing the amount of blue light emitted from the screen of your gadgets not only helps you work better (particularly at night) but also helps you sleep better.

Majority of smartphone manufacturers are increasingly adding support for “Blue Light Filter” on their products as a built-in feature, and it’s already quite popular.
