Apple’s mixed blue light messaging

Apple Eye Health rect 1

Apple has been extremely progressive on its users health in all aspects, and has provided tools to help people enrich their lives. They launched the Apple Watch in 2015, and it originally focused on calories, standing, and exercise, and it has evolved to include ECG, Blood O2 and even hand washing with the introduction of watchOS 7. They’ve been involved in countless health studies, including the largest cardiovascular study ever recorded thanks to their Research app. Fitness+ is even coming later this year to help with in-home fitness using devices people already own. They also took it a step further and started to tackle eye health with the introduction of Night Shift and Dark Mode.

Apple introduced Night Shift alongside iOS 9.3 back in March of 2016 and has become a feature in iOS, iPadOS, and macOS that is either loved or hated. Apple states that Night Shift “automatically adjusts the colors of your display to the warmer end of the spectrum—making the display easier on your eyes.” I personally love it on my iPhone, and iPad and have it set to automatically turn on and adjust as the sunsets and turn off when the sunrises, but I have it disabled on my Mac because of the amount of times I have edited photos and videos with it accidentally enabled.

A few years later, with the introduction of macOS Mojave and later the release of iOS 13, Dark Mode was brought to their operating systems, further pushing their claim that warmer colors (or black in the case of Dark Mode) makes your displays easier on your eyes.

Then, with the launch of iOS 14.2 and macOS Big Sur, Apple has introduced brand new wallpapers that switch to a Dark Mode variant when the system switches to Dark Mode. With previous wallpapers that they’ve released that do this, they switch to darker colors, or just a black background…but with the new wallpapers, they switch to a blue background which seems to defeat the purpose of Night Shift.


To further complicate things, Apple also introduced larger variants of these wallpapers in macOS Catalina. So, is Apple taking a step backwards on eye health, or is Night Shift just that good that it counteracts the full screen of blue.
