If you use your phone, laptop, or tablet for long hours every day, you’ve probably felt how harsh bright screens can be on your eyes especially at night. That’s where Dark Mode comes to the rescue. Dark Mode is not just a stylish setting that changes your screen color.

It’s a practical feature designed to make your digital life easier on the eyes and even help your device save battery. From Android and iPhone to Windows and Mac, almost every platform now supports it. In this complete guide, you’ll learn what dark mode is, why it’s useful, and how to enable it on all your favorite devices and apps step by step.

What Is Dark Mode?

Dark Mode (also known as Night Mode or Dark Theme) is a display setting that changes your device’s interface from light to dark colors. Instead of bright white backgrounds, you get deep black or dark gray tones with light-colored text.

This makes it much easier to look at your screen in low light, reducing glare and making it more comfortable for your eyes. Dark Mode also gives a clean, modern, and professional look to apps and websites. Which many users now prefer over the classic bright theme.
