Achy eyes after too much screen time is a quintessentially 21st-century problem. Now the smartphone has been with us for over a decade, handset and app manufacturers have finally given us dark mode, which switches your white screen space for shades of grey and black. PCmag has an article from Jason Cohen, sharing how to set up dark modes in some of your favourite apps.

It’s quite eye-opening to see the stats on how long we spend looking at screens. In 2018, the average American adult had 3 hours and 35 minutes of screen time, and this year eMarketer predicts mobile time will surpass TV time for the first time.

Having so much light hitting your eyes isn’t great. Light at the blue end of the spectrum messes with your sleep patterns because your brain still thinks it’s in daylight. A utopia without mobile devices isn’t going to happen any time soon, so the next best option is to set up dark modes on your apps, turning your whites to greys and blacks instead.

The dark mode isn’t yet a standard option in all apps, there are some that have night themes that will only work when certain parameters are hit. Navigating at night with Google Maps will kick in the night theme but you can’t set it to work over the whole app. Firefox, Gmail, and Windows 10 Mail apps do have custom web themes available, but they’re hit and miss when it comes to their mobile apps. 

There are OS level dark modes available; iOS 13 on your iPhone and the latest Android 10 update both will make your whole phone go dark. It’s only going to work over apps that support the change though, such as built-in Apple apps and most apps developed by Google, and third-party apps that already have dark mode such as Instagram.

We’ve put together a list of apps that have their own dark mode and a quick guide for how to get it turned on and give your eyes a break.
