Malcolm Owen, AppleInsider:
The concept of smart glasses runs into a problem when it comes to people who normally wear glasses to see. Those who can wear contact lenses could feasibly use a typical smart glasses setup without too much issue, but those who have to wear glasses can end up in trouble.
This is all conjecture, of course, since we don’t actually know if Apple has glasses in the works and, if they do, what form factor they will take.
But the linked article is an interesting read, with discussion of actual Apple patents that would make sense if prescription-tunable lenses are in the works.
And if that is the case, it raises the possibility of Apple glasses being a product that would be useful without any internet connectivity at all. Imagine having adjustable lenses for your glasses, able to zoom in on something that would normally be beyond your range of vision, for example.
Or switching between far view and detailed close up view, sort of like bifocals or progressive lenses, but with a full field of view and the ability to change on command. Need to read a far away street sign? No problem. Thread a needle? No problem. Same lenses, just a Siri command away.
Yeah, I get it, I’m dreaming. But still, that’d be very cool.
