But you can't physically look at two points at once, without moving your eyes independently.
Google AR Glasses?....out of date.

Indeed, that's why the lens does everything for you, regardless of what you're focussing on in the distance the HUD will be adjusted to suit that focal length so it is always in focus.
Which is damned amazing and for a sniper especially invaluable.

120? I used to play Quake 3 at 130 fov

Bet it'd give me a monster headache

Not with conventional lenses, no. But the human eye is different. Hold out your arms and move them forwards until you can see both of them. I bet you don't have to move them that far.
They are really talking about field of vision rather than field of view, although the terms are often used synonymously they are different. Also they are referring to binocular vision rather than full visual field.
Human FOV is about 180deg, but binocular vision is limited to 60deg, the same as your field of vision. The mixed use of the terminology doesn't make it easy.

So you're saying it gives you an infinite depth of field? I thought the only way to do that 'on the fly' was to use a pinhole. If it's doing a sort of HDR technique then there would have to be a delay between the light entering the lens and the light entering your eye, while it processes the image... yes?
No, it means that if you are focusing on a distant target that the HUD data stream will also always be in focus so you do not have to shift focus from the target to the hud. Basically both images are received by the retina in focus simultaneously.

so take the glasses off?
They must be working on one hell of a training program, that's for sure!
yeah it's a really hard one, "put contacts in....continue as normal till bed time ...remove contact lenses and clean or dispose depending on type....sleep ...wake up insert contact lenses....
Repeat for a week, congrats you're now adjusted.

Okay, i think i see (no pun intended
). So the HUD is projected into the lens from an external source, and the curvature of that light is controlled to match that of the light entering from the point you're focusing on. Even so, that must require a large amount of processing power to do without any significant delay...it's just bringing the focus of your eye o nan object les than one inch in front of it to the same distance as light from further away, when you take the glasses off al lit means is you can see clearly like normal but you're also focusing on the empty space 2 cm infront of your eye ball, so you wont notice it.
Okay, i think i see (no pun intended
no it's done by the lens.... so zero processing power.

The normal view through the contacts is unaffected, it is what you would focus on normally, no different from wearing a normal pair of contacts....the HUD information is projected onto the lens and then the lens focuses that so that both images are received by the retina in focus....
I do not see why there would be any significant delay, it isn't that much different from current tech only insofar that you receive the hud image in focus regardless of what your eyes are focusing on at the time.
Like Tefal says the image is being focused at the speed of light....

Hmm... not sure that would work exactly. The only thing i can think of would be if the HUD is projected using a specific wavelength of light, and there is a layer on the lens that only affects that wavelength? I can't think of any materials like that though, and i'm not sure how that would stop it being thrown out of focus by the lens in the eye.

You will not be alone in this respect as I would imagine a lot of people will ignor them for this reason.
