Google AR Glasses?....out of date.

Draw something on your glasses then try and focus on that, all it does is add a second less to your eye to do that bit for you.
the fact you still haven't read the article probbaly isn't helping.
what these are are basically varifocal glasses in contact lens form.

I read the article, it doesn't really explain how they work. How one filter somehow causes part of the eye to remain fixed focus while the other allows everything else to work normally.
Varifocals don't allow you to focus on two points at once, they allow you to focus at different distances depending on which part of the lens you look through. Normally you have to specify what they're mainly used for - reading, sitting at a computer (although i'm sure every time i've specified that the focal distance has been like two meters), driving/whatever so they can set the focal distance appropriately.

I thought it explained the process clearly. There are two focal filters, and centre and outer filter, the image from the HUD is projected through the centre filter while the eye looks through the outer filter, this allows two images to be focus onto the retina at the same time.
All the two filters do is effectively focus two images onto your retina simultaneously. It has nothing to do with the eye, it is the lens.

We've had this principle used for some time post cataract surgery. The problem is not the eye part it's the brain part and it tends to mess up both images so you loose perception/movement detection etc all the sort of things that you'd kind of want in spades in the kind of soldiers that you'd want to be using this sort of tech.

But the lens in your eye changes shape, by my understanding the contact lens shouldn't. So how can some of the light being filtered stop the image being out of focus when the eye lens adjusts to different distances?
Read the article.
And how do you think normal contact lenses work exactly, the question you just asked would apply to them, and glasses for that matter.

Yeah, the article mentions that there is contrast degradation when similar techniques are used in cataract treatment, and that motion sickness is also a risk.
That is not to say that these issues are insurmountable however.
however (questionable as it may be) military tech has much more funding than therapeutic technologies so is more likely to solve the issue.

Yeah, i have. Both the BBC and the smartplanet ones. I guess the most descriptive it gets is this:
The central part of each lens sends light from the HUD towards the middle of the pupil, while the outer part sends light from the surrounding environment to the pupil's rim.
But that doesn't explain how the image would stay in focus, because the light from the HUD is entering from the same distance, through the same filters to the retina which is the same distance away, but it will still have to go through the lens in the eye which has variable power depending on how far away the object you're looking at is.

I constantly forget I am wearing contact lenses, so much so that despite being severely short sighted from the age of about 7 I tend forget I need glasses at all. Wearing the all day all night lenses means that when I take them out suddenly being basically blind again is quite a freaky experience.
GIVE ME THESE LENSES! I want cool enhanced reality now damn it.

That would be why there are two filters.......They direct the light in different ways...each works like an independent lens.
Watch the video in This Article

Ah, it has to be polarized... so presumably at least one of the filters will only let through light polarized to that pre-determined angle.
Still, needs more ray diagrams

Mark a target in a hedge, and everyone in the squad can see it in their heads up without a word being said.
Upload mission details into it, so it shows target buildings, known IED's etc.
Mark friendlies with it.
Possibilities are endless...
edit: May have confused those google glasses things with these, despite the title...

I can imagine 'spotter' data uploaded in realtime from wide angle observation posts enabling a sniper to make accurate materiel targets without clear line of sight....maybe even personnel targetting if the tech is up to it and can show real time video feeds.
Not sure they actually can with this technique because it is something that is to do with how the brain processes the image rather than a pure optics problem. One interesting thing would be the genetic variation that would expose these factors - it may well be something that a country such as Japan or China would not be able to use due to their raw genetics and how they are more prone to induced motion sickness. They can copy this all they want but most likely would not be able to use it.
To be of relevance the information given would have to be updated and therefore is perceived as movement - with the visibility it would require to be observable and legible it would most likely serious confuse the brain in relation to threat prioritisation eg recognising relevant movement at split second timing. There are also problems related to size interpretation @ Castiel think of scale of longshots where all the trees and houses and people go funny sizes and image that across all distance ranges. Would hardly increase combat effectiveness. A think it's a while yet before we have fully functional 'street samurai'.
edit: I'll ask a couple of my friends who are consultants at the Moorfields they'll know better than me and one of the is rather pro-tech and uses 3DS as a treatment modality - so he would be a good person to give an impartial view.

is it potentially controllable with medication?
Not really as you are dealing with the way the brain processes information to form images which has a lot of learning and evolution behind it. I am sure it was sold as an amazing idea to some senior military commanders but these are the kind of people who'll happily purchase aircraft carriers without aircraft and destroyers that can't destroy other ships.
Edit: I should say motion sickness would also potentially treated by medicines that would cause drowsiness, hallucinations and other things you wouldn't want a soldier to have.
