Google Glass is Google's smart glasses with an uncertain future. Mixing virtual reality and reality has apparently (at least for now) only been virtual reality for Google's revolutionary Google Glass, as it is no longer on sale as of today. But that doesn't mean their future is sealed. Smart glasses give way to a new version (it is not yet known when it will arrive), which will eliminate all the shortcomings of the first - a "swish" battery, an unfinished screen, poor audio support and an unaffordable price.
