I am not a fan of this big glasses trend in general. I am not into looking like I just stepped out of the 60's & 70's. With that said these glasses take that even farther yes they do more than what a regular set of glasses do but OMG those things make the lady in the video look a bit odd as they are way way over sized for her face and just look very ugly the glasses I mean look ugly had to clarify that.
If they can down size the frames as in make them thinner and down size the ear arms so they are not big and bulky they could be pretty cool to use.
This tech is big progress and should get North bought out by Google,Apple or Amazon. Sounds like very few pairs will actually be sold and used now but 10 years from now this will be totally viable tech.
