Hi!

I'm the Founder & CTO of Envision. We're building EXACTLY the product you're describing. Envision Glasses is a bunch of computer vision tools built on top of the Google Glass Enterprise Edition 2. We've more than 2000 visually impaired people, across the world, using the Glasses in more than 30 different langauges.

P.S: I know the EE2 has been discontinued but we've been working closely with Google to ensure current and future demand is met. We're also experimenting a lot with other exciting off-the-shelf glasses that I can't talk about here but I'm super excited for this whole glasses + AI space!
