Smartphones Can Cause Nearsighteness

I think we all intuited this was happening.

  Smartphones should really be used for looking up information quickly at a glance. When you need to do something for longer periods of time, you should use different devices. To prevent nearsightedness/myopia, you can use AR glasses, VR headsets, projectors, TVs, etc. instead of using monitors or reading physical books. The aforementioned devices keep your eyes relaxed (accommodation-wise) over long periods of time.

Just as reading books all day will [1]. Seems like the researchers are not interested in telling you that, however. Children spend most of their time indoor—would you want something to happen to them outdoor? Surely not, right?! But surely it must be those pesky screens. If that's not clickbait, then that's a hugely sensationalist title to something that is at best ignorant and at worst misinformation; I don't usually flag posts but I'm flagging this one.

  Can we have a lens that covers the entire display that collimates the light so you're actually focusing on 1-2m away or infinity, like in a VR headset?

    I've been thinking about digital glasses that would correct your vision digitally (i.e. with pixels). Similar to your idea I would say! Not that I would choose them over regular glasses but now that I have the idea in my head I can't help but think about it. I'm not in the field at all, though.

    AR glasses like those from Xreal are like that. You can use them as a display for a smartphone, tablet, computer, etc. I have Lenovo Legion Glasses 2.
