This a bit of an aside, I have slight astigmatism, and I have some prescription glasses in a drawer somewhere that I haven't put on in ten years. Fixing my less than perfect vision is not worth the hassle of having to wear a device on my head all the time. I haven't worn a watch on my wrist since...probably elementary school--so the 70's. For a few years I carried a pocket watch, now my cell phone is my pocket watch, and that is a significantly better situation than wearing a piece of tech on my wrist. So it seems like the all the tech companies are trying to make me wear something that I have already concluded I don't want to wear. In the case of watches it seems less strange--plenty of people love watches on their wrist. So Apple and Motorola can sell to them. But the only people who wear glasses are people with vision problems. They do their best to make them comfortable and fashionable, both I don't know anyone with good vision wishing they could wear glasses. So if Google can make a version that works with prescription lenses, and sell to people that need them, but it seems like it's going to be a much harder push to get people who don't wear glasses every day to commit.
