iPhone now alerts you when you’re too close to the screen

We all know that excessive and prolonged exposure to TV, smartphone and computer screens can have negative effects on the health of your eyes. In this sense, Apple has now created a function in the new version of iOS that alerts you when you are too close to the screen.

According to CUF, nowadays, with the development of technology and the adoption of protective filters for most screens, talking about radiation harmful to health has already become a myth.  However, excessive eye exposure to electronic devices is still harmful.
These are some of the most common symptoms:

Dry or watery eyes
Eye irritation or itching
Visual sensitivity or light intolerance
Blurred or tired vision
Difficulty concentrating

In this sense, Apple has created a new function for the iPhone.  This function is already available in iOS 17 and can be activated for those who have already installed the beta.  The new feature is called Screen Distance, and as the name suggests, the goal is to reduce eye strain.
How to activate the new function on iPhone with iOS 17?
To activate this function, you just need to go to definitions > screen time and activate the option screen distance.
According to Apple, this feature, which is optional, was developed with the aim of reducing the risk of myopia, especially in children.  The goal is to encourage visual habits aimed at reducing eye strain.
The feature makes use of the TrueDepth camera, which has the ability to measure the distance between the screen and the user's eyes.

The alert appears when the iPhone detects that it has been at a distance of 30 cm from the eye for an extended period.
iOS 17 is still in beta and can be tried on all supported iPhones.  The final version should only be released in September.
