How to Turn on Safari's Dark Mode via MacOS
At night, black text on white backgrounds is particularly tough on your eyes. It's very simple to switch on Dark Mode for your Mac. It doesn't just turn on Dark Mode for Safari, it does so for all your apps but that's perfect for protecting your eyes late at night or in dim lighting conditions.
Dark Mode is only available in macOS Mojave or later.
Click the Apple icon on the top left of your screen.
Click System Preferences.
If you want the dark appearance to only appear at night, you can click Auto for it to automatically adjust as the day progresses.
All websites that have been designed to support Dark Mode will now show in a darker form than before.
How to Switch off Safari Dark Mode
Switched on Dark Mode and realized you don't like it? It's simple to switch it back off.
As above, click the Apple icon on the top left of your screen and then choose System Preferences > General.
MacOS and Safari will now return to the light background permanently until you choose to switch it over again.
How to Use Safari Reader View to Turn on Dark Mode
Depending on the website you're viewing, the only thing that may go dark with MacOS's Dark Mode is the buttons and menus around the website. To ensure the site goes fully dark to protect your eyes, you need to use Safari's Reader View.
Safari Reader View only works on certain websites. Often, this is restricted to blog posts and other text-heavy websites. It's worth using when able to though.
On the website you want to view, click the Reader button on the left side of the search field.
This only appears on websites that support Safari Reader View.
Click the letter button on the right side of the search field.
Click the black background to change the background color.
You can also adjust font size and font choice here.

How to Use a Dark Mode Extension in Safari
The above solutions work only on a limited number of websites. If you want to enable Dark Mode for every website, you need to use a Safari extension. Many of these cost money but they can be useful. We recommend using either Night Eye which is free but limited or paying a one-off fee for Dark Reader. The process is the same for both extensions.
Install either Night Eye or Dark Reader from the Mac App Store.
Open Safari then click Safari > Preferences.
Click the Extensions tab.
Check the box next to your newly installed extension to enable Dark Mode.
Both of these extensions should convert the vast majority of websites to Dark Mode as and when you need it.
