I had a Google Glass 2 recently for a couple of weeks. It came as part of an app called Envision that was created to make blind people’s lives easier by offering functions such as OCR, facial recognition, And product recognition among others. I really liked the glasses, including the navigation paradigm, but I can’t comment on screen quality. The glasses felt quite flimsy, and fell apart a couple of times as I was putting them on. They are very light and comfortable to wear.
