If you’re having trouble sleeping at night or your eyes are feeling strained, it might be because your computer screen is too bright. The white light coming from our computer monitors, smartphones, and tablet screens was designed to look like sunlight. So, staring at our screens all day is kind of like staring at the sun all day. However, it’s the blue light coming from our screens that causes the most discomfort. Using dark mode on your computer or smartphone will take your bright white background and turn it black, which will reduce glare and help your eyes adjust to surrounding lights.

The contrast and colors used in dark modes also make it easier to watch videos on YouTube or Facebook. Here is our list of best dark mode extensions that can reduce the blue light coming from your screen:

Best Dark Mode Extensions for Chrome, Firefox, and Safari

Dark Reader

Dark Reader can make any website darker, but unlike most dark mode extensions, it doesn’t just invert the colors on your screen. This extension also lets you adjust the brightness and contrast of any webpage and save those settings for later. This is especially helpful if you are just starting to use dark mode and it’s too much of an adjustment for your eyes.

Dark Reader also comes with a sepia filter that takes out even more blue light, as well as font settings that make it easier to read the text. And, if you only want to use night mode on certain websites, it comes with an ignore-list that you can quickly populate.

Dark Reader is available for Chrome, Firefox, and Safari on Mac and PC.
Available for: Chrome | Firefox | Safari
