Turn on Screen Distance in Screen Time on Mac
Viewing a device (or a book) too closely for an extended period can increase the risk of myopia for younger users and eye strain for users of all ages. The Screen Distance feature in Screen Time uses the TrueDepth camera (on supported models)—the same TrueDepth camera that powers Face ID—to detect when you hold an iPhone or iPad closer than 12 inches for an extended period, and encourages you to move it farther away.
Screen Distance can remind younger users to engage in healthy viewing habits that can lower their risk of myopia. It can also help adults reduce eyestrain.
Screen Distance is turned on by default for children under 13 (age varies by country or region) in a Family Sharing group.
Screen Distance works only on your iPhone or iPad. When you turn on Screen Distance on your Mac, the setting applies to your iPhone or iPad that’s signed in to the same Apple Account. There are no alerts if you’re viewing your Mac too closely.
Note: To use all the latest Screen Time features, you need version 27 or later of iOS, iPadOS, macOS, watchOS, or visionOS on all your devices. If you’re setting up these features within a Family Sharing group, all devices in your family must be upgraded to version 27 or later of iOS, iPadOS, macOS, watchOS, or visionOS 27. Learn how to update your Apple devices.
If you want to set up Screen Time or parental control features for your child, see Apple Devices for Kids and Families. | |||||||||||

When you hold the screen too close to your face for an extended period, Screen Distance covers the screen with an alert, preventing you from continuing. When you move your iPhone or iPad more than 12 inches away, you can tap Continue to resume using it.
