If Google Glass can be used to initially see a patient, before they show up at the doctors office, they might be able to have the reassurance they need, that they are not very ill, and get a prescription to help them get better, without actually going in. This is the future of healthcare.
Google Glass is a gimmick that will not last. Google has a good advertising department, but their products are not really very revolutionary. Other companies can produce electronic glasses in the same way. Google's glasses aren't even available to consumers right now. Google has big ideas, but most of them will never come to fruition.
