Apple introduces the screen distance function in iOS17, and the safe distance reminder can avoid eye fatigue
iOS 17 is the next big software update for Apple’s iPhone.
At WWDC 2023, the new OS brings a lot of features. Among them, there will be a refined Control Center, which offers many customization options. The update also brings fine-tuned apps to the system.
In addition, a special feature of iOS 17 that can help users avoid eye strain is called “Screen Distance” (Screen Distance), which, as the name suggests, makes it easier for mobile phone users to keep the iPhone screen at the optimal distance.
Apple says it’s an optional feature, meaning users can choose whether to turn it on. But it turns out to be eye protection. If you upgrade to iOS 17 in September, turn it on.
What is the setting of the screen distance function of iOS 17 based on?
It’s easy for us to immerse ourselves in what we do on our mobile phones; whether it’s playing games, watching videos, or simply browsing Moments or Weibo, we may unconsciously bring the mobile phone too close to our eyes. Looking at the screen too close to the eyes for a long time can cause eye fatigue. To protect the health of users’ eyes, Apple introduced the screen distance function in iOS 17.
iOS 17’s Screen Distance feature takes advantage of the iPhone’s TrueDepth camera. Yes, it’s the same sensor that’s responsible for facial recognition, which can be used to unlock the phone. Now it has been given more functions; through the sensor, the process can detect the distance between the eyes and the mobile phone’s screen.
When the Apple mobile phone or tablet finds that you have held the phone too close for too long, a pop-up window will pop up on the screen to remind you: “You are too close to the iPhone/iPad.” This feature tells you to hold the device away from your eyes to prevent fatigue. Isn’t this feature cool?
How does this feature work?
We know that a distance of 16 to 18 inches (approximately 40-45cm) between your phone and your eyes is optimal. For most people, that’s an arm’s length away. This distance reduces eye strain and keeps your eyes healthy. On the other hand, a feature in iOS 17 will warn you when the phone is within 12 inches (about 30cm) of your eyes.
Of course, it can also avoid misjudgment. The function of iOS 17 will only give a warning reminder when the user holds the phone too close for a few minutes. Therefore, the screen distance function will not remind you immediately after looking closely at something on the screen.
A checkmark will appear on the screen after you’ve moved your device to a safe distance. You’ll see a “Continue” button that, when clicked, will do what you’re doing on the screen. Along with the warning, the pop-up reads: “Keep a distance from your phone to protect your eyesight.”
How to turn on the screen distance function of iOS 17?
The screen distance function of iOS 17 is turned off by default. As mentioned, Apple says this is an optional feature. It means you need to turn it on manually. To do this, click Settings, then Screen Time, and find the Screen Distance option. This feature turns on when you tap the button to the right.
Apple says the feature is compatible with the iPhone XS and newer models. The feature will also be available in iPadOS 17 for 11-inch and 12.9-inch iPad Pro models introduced in 2018 or later. If you want to enable this feature, it will be allowed on the official version of iOS 17 and iPadOS 17, released after October this year.
