How To Move Between Light & Dark System Modes on Windows 10


Technology has been a great boon for us. From being able to look at maps on our screen, creating designs for art and posters to booking flight tickets, we rely heavily on gadgets to get our work done. This has made it more and more difficult to avoid a screen for a long period. Be it an endless day at work or a movie marathon on Netflix over the weekend, looking at a screen for long hours is inevitable. This has caused many chronic conditions such as eye problems and Carpal Tunnel syndrome.

The main reason for eyes getting damaged by computer or mobile screens is the harmful light that the screen emits. To avoid this issue, Windows has introduced a dark mode that reduces the number of harmful rays emitted by the screen and helps you concentrate on your work for long hours without worrying about the adverse effects it has on your health.

The light theme is aimed at achieving the exact opposite result. It allows the computer screen to use more energy and emits harsher light. This allows the screen to look brighter and can be used in an outdoor environment on a sunny day without having to squint to read every letter.

The availability of these two modes and their contrasting yet useful characteristics, helps users take care of their eyes and protect them from damage as much as possible.

Here is how you can alternate between light and dark mode on Windows 10 PC-
