Vision Health Was the Apple of Apple’s Eye at WWDC 2023 – CNET

We already know spending hours on-end staring at screens isn’t easy on your eyes, but monitoring the screens-to-sunlight ratio may be especially important for children whose eyes are developing. 

At Apple’s Worldwide Developers Conference Monday, the tech company leaned into the prevalence of myopia — the medical term for being “nearsighted,” which affects almost one-third of us (30%) — with updates to its health features on watchOS 10, iOS 17 and iPadOS 17.

While everyone could benefit from more time spent outside and away from screens, children whose eyes are developing can especially benefit from more time spent outdoors and potentially reduce their risk of nearsightedness. (Between 80 and 120 minutes of outdoor time is recommended for school kids, per one estimate from the International Myopia Institute.) Apple says it can help with this by allowing Apple Watch owners to monitor how much time they spend in the sunlight with an ambient light sensor from watchOS 10. 

For kids who don’t have an iPhone, parents can use Family Setup to pair their watch with their parents’ phone. (Of course, this means you’ll have to get your kid an Apple Watch to use the sunlight-tracking feature.)

In other vision news, Apple announced a Screen Distance feature that encourages people to move their device farther from their face if they’ve been holding it close for too long. The distance feature uses the same TrueDepth camera from iPad and iPhone.

Remembering to keep your devices book-reading distance or more from your face will help adults stave off symptoms of eye strain, but Apple also draws on a similar body of myopia research that finds kids, especially, may reduce their risk of myopia by limiting their exposure their screens.
