There are many medical applications. One is remote care and surgical follow-up. In many places getting access to a specialist is difficult (esp for Pediatric and Derm). A nurse would wear Glass and act as a proxy for the remote specialist doc or allow for follow up post-surgery. This is a big deal for remote communities that have poor health outcomes because of lack of access. In the US there's no incentive to reduce cost or provide better care (really) so it's a hard sell.
Remote support is really targeted at operations that have a high cost when it's not working (like manufacturing) and have a high degree of sophistication. A lot of times someone might need to drives hours or get on a plane from some other location to address the issue.
There were issues with all the products, but for my money Glass or Realwear was the best solution. Glass if it needs to be easy and Realwear if it needs to be robust. I can be more specific if you like.
