Well, now in the digital age Eyewear assume a new, expanded position. They are computer and so close to us as never before a computer - in form of "Smart Glasses", data eyeglasses.
And as a computer they can make much more than the traditional devices, desktops, notebooks or smartphones: You can pretend us as "virtual reality" instrument an artificial reality. Or as "Augmented Reality" to extend the real reality with artificial reality.
Sounds all too much like science fiction, but just take a look in the storage / warehouse or industrial production halls in the industry. There data eyeglasses have long gone beyond the testing stage, where they support employees and raise productivity sharply because they are monitored themselves in live mode.
In the consumer world Google's data glasses failed on data protection but in the production world these data Glasses are long beyond the testing phase and becoming a normal for a company to help employee’s to perform their tasks more efficiently which in turn is good for the companies economy.
Now we can see people seem to be not only intelligent with glasses, now they are really helping with deficiencies in intelligence.
