Glass is not enough for Google. They want more of the real estate located on your eyes, as crazy as it sounds. To do this, Google has patented a system in which cameras would be embedded into contact lenses. What would this accomplish? Taking photographs of exactly what a person sees.
You may recall that the company was talking to the FDA about contact lenses to measure glucose levels. This, however, takes the purpose of these contact lenses much further. And Google may want to hurry as Samsung is reportedly working on a set of smart contact lenses, too.
