Open your device's Settings app . Select Accessibility. Under "Color and motion," turn on Dark theme.
Note: This feature is called Dark mode on Desktop and Dark theme on mobile devices. When you browse in Dark mode or Dark theme in Chrome, your homepage, toolbar, settings, and some other pages will be dark.
Also, Dark mode emits less blue light, which reduces eye fatigue and blinking (dry eyes), especially in low light conditions. Dark mode contributes to a better sleep if you worked before going to bed, which can be translated in a better work efficiency on the next day.
Alternatively, right-click on your desktop and click “Personalize”. Step 2: In the settings, first select “Personalization” and then “Colors”. In Windows 10 this is on the left, in Windows 11 it's further to the right. Step 3: You can now select the “Dark” option.
+ Click on the extension icon to turn on/off the dark mode or use shortcut: Ctrl+Q (Windows, Linux, Chromebook), CMD+Q (Mac).
A new study highlights only 3 to 9 per cent of power-saving on OLED screens in average brightness through the use of dark mode. Peak brightness can increase this to battery saving to about 39 to 47 per cent.
Dark mode may increase eye strain in brightly-lit conditions. Dark mode can cause halation for individuals with myopia or astigmatism, making text less readable for them. Dark mode may lower reading comprehension and focus. Dark mode does not improve battery life on older devices without OLED screens.
Reduces eye strain at night and cuts glare
Dark mode users find reading easier in low light with less eye strain. They also claim it helps them fall asleep quickly and stay asleep longer. This could be because screens expose you to more blue light at night, which could disrupt your circadian rhythm.
Turn off dark mode for Google Chrome

Dark mode swaps the traditional white background for a black background. It's available on Android phones, Apple phones, Windows 10 and macOS. Even Firefox and Chrome have their own versions of dark mode.
Ultimately, visual performance tends to be better with light mode for most people. However, some people with cataracts and related disorders may prefer the visuals provided in a dark mode.
New research is detailing how blue light, which emits from smartphone and laptop screens, can damage your retinal cells, and possibly lead to macular degeneration, an eye disease that causes vision loss.
Cons: Dark themes are not always better for eye strain. In bright light conditions, the text appears washed out, increasing eye fatigue. Long pieces of content or text are more challenging to read in this mode.
Studies show young people are particularly susceptible to blue light affecting sleep. Luckily, our technology has adapted. A simple way to avoid both sleep disruption and eye strain is to turn on night mode on our iPhone or Android devices.”
The most fruitful battery life gains were found when switching from light mode at full brightness to dark mode. In the Purdue study (via Android Authority), researchers looked at dark mode power usage from six different applications.
Changing from light to dark mode reduces the phone's power consumption by 42% at 100% screen brightness. When the brightness level is 50%, switching from light mode to dark mode saves 9 % of the battery, and when the brightness level is 30%, the saving is only 3 %.
Wearing blue light glasses may sound like a good solution, but a recent study determined there was little evidence to support the use of blue-blocking filters in the prevention of digital eye strain.
Yes, you can use your smartphone while charging. There is no danger in using your phone while it's charging. When you use your phone while charging, the battery is charging at a slower rate than normal to allow enough power for the ongoing usage.
Diet, smoking and excessive alcohol can all make a difference to your eyesight in the long run. Long-term effects of consuming too much alcohol can increase your risk of eye disease, including AMD and cataracts.
