I know who that is! That's the guy with the funny glasses!
Technology like this does not prevent recognition unless lots of people are using it. One glance at the glasses, and I doubt there will be much uptake.
They could also actually identify you if they flashed in certain patterns or had slightly differential brightness. The paranoid might have to avoid them or make their own...
I doubt you would wear them 24/7, and you'd only want to wear them if you intentionally did not want to be recognized (at an airport/casino/robbery) but the fact that you had them on would draw attention to yourself, plus I suspect it'd be easy to trace back to the purchaser if the adoption rate were low.
As someone who's worked with computer vision, I doubt this is fully effective. It might prevent an exact match, but a good facial recognition algorithm can still whittle down the total possibilities. That's because your cheeks, ears and nose are also used as identifying features. The only effective cover is something that covers whole face.
Yeah, for it to be truly effective it would be to have some sort of halo of IR LEDs that are brighter than the ambiant surrounding light. This is probably not viable due to power requirements/cost.
Almost all image sensors see near IR very well. Most consumer lens block IR very well, to make image similar to that perceived by human. Not so for CCTV lens: they don't block IR to allow human-invisible lighting via LEDs just like in these glasses.
Try filming an IR remote control (while pressing a button) with your phone's camera. It'll light up. I think it's pretty cool actually :) (might need to do it in a dark room, depending)
I suppose the GP was talking about actual non-phone photo cameras?
You could wear these glasses, perhaps in addition to CV Dazzle[1], and be instantly recognizable in real life, and yet unrecognizable to computers. It's an interesting trade off.

Also: RGPs, as in http://en.wikipedia.org/wiki/GI_glasses
[When I was 10 I had black nylon frames like those, and yes, I was made fun of a lot, so I became a kernel hacker :-) ]
Let's say I have a camera that cannot record in IR range, just the full spectrum. I can still run a facial recognition software using those photos.
I am well and truly lost about how it works
