How do these work ? Do they project on the lens, or on your retina ? Is there any possibility these might be good for people who already wear glasses?

- jordhy 15y agoThey project on the lens, on a peripheral area that doesn't obstruct vision. I guess you can wear contact lenses behind them.
- replax 15y agoAlso, it would probably be possible to use lenses in the glasses with a certain dioptre strength applied, so that people could use those instead of their regular glasses.
- jahewson 15y agoBut there are no lenses in these "glasses"...
- teraflop 15y agoI'm not sure now where I read it, but I've seen speculation that the glasses contain a flat holographic optical element which takes the place of a lens. There seem to be existing products that use this approach: http://www.konicaminolta.com/about/research/core_technology/optical/mgt_001.html http://www.konicaminolta.com/about/research/core_technology/... http://www.digilens.com/Head_Mounted_Display.html http://www.digilens.com/Head_Mounted_Display.html
- jahewson 15y agoNeither, there are no lenses, really we should call this a "headset" rather than "glasses". There's a small rectangular glass screen which is projected on to. Seems like there would be no problem wearing contact lenses with them but not glasses.
- jrmg 15y agoHow does that work? If I hold a screen that far from my eyes, it's just a blurry mess (and I'm near-sighted!)
- valisystem 15y agoThe image won't be focused on the reflecting glass, and the glass won't be flat. If you are near sighted, I suppose you have glasses, to figure out what's happening just try to look at the reflexions on the convex (exterior) side of your glasses, and you'll see you will manage to see a clear image much nearer than usual.
- hastur 15y ago1) Scoble wrote Brin's glasses had lenses. 2) If it were just the tiny rectangle, wouldn't they be very inconvenient? I mean, I would have to look up constantly, instead of having image projected on my field of view. Pretty tiresome in the longer run. Plus, the "screen" would be too tiny, even this close to the eye. I know the demo video was just CG, but it did suggest that the image would be projected across the whole field of view. (Well, the "main" part at least - i.e. whatever your typical glasses cover.) So I'm really hoping this tiny rectangle is just a reflector / prism that projects the picture on glass lenses or the eye itself. Otherwise it's just not good enough. (And I disagree this would obstruct your normal vision. The projected image would be semi transparent and it would affect just one eye.)
- Symmetry 15y agoWell, I didn't see anything in the article where Scroble mentioned whether they had glass lenses or not, but did you look at the pictures in the article? There were very clearly no lenses.
- zephjc 15y agoDo you mean your eye's lens, or an external lens? I think there is some confusion in these child comments over which you mean. At any rate, it seems it projects onto your eye's lens
- ilaksh 15y agoAt this point we don't know that they do anything. The blue light could be just for effect for all we know. It might just be a way to hype the product before they have a functional prototype. I think if we want them to demo the actual product and show us what it really does, we should start telling Brin and the rest that we don't believe there is a real product. Why should we believe that anyway unless they demo what it can do? That marketing video doesn't prove anything. It probably isn't anything like that actually.
