The optics used in AR/VR headsets typically make your eyes focus as if they were looking at a point anywhere between several feet in front of you and infinity, so it shouldn't advance myopia. Hard to say about the light emitted though.

I'm interested in seeing how it works with glasses.

I know there's supposed to be some kind of custom magnetic Zeiss lenses you can pop in, but I don't fully understand how they're supposed to work — do they replace your glasses, or are they to adapt your glasses vision to an AR space.

There were a few tidbits in the iOS and watchOS portions of the recent keynote focusing on vision issues, so it's nice to see Apple taking it seriously. But I don't understand the solution.

I believe most damage is done in your prepubescent years. Using this or phones really should be limited until your eyes finishing changing and then you're gucci. I recall that Singapore went from 17% myopia to around 80% in almost a generation due to the lack of changes in distances that your eyes see in your younger years.

As someone with already terrible eyesight from intense gaming, having a screen even closer to my eyes doesn’t sound like something I’d be interested in. Just doesn’t sound healthy at all.

Well, you only have to pay $3.5K to find out!
