Smart contacts: The future of the wearable you won't even see

• https://newatlas.com, By Nick Lavars

Material science and our understanding of the human eye have come a long way since, while their purpose has remained largely the same. In the age of wearable computers, however, scientists in the laboratories of DARPA, Google, and universities around the world see contact lenses not just as tools to improve our vision, but as opportunities to augment the human experience. But how? And why?

As a soft, transparent disc of plastic and silicone that you wear on your eyeball, a contact lens may seem like a very bad place to put electronics. But if you look beneath the surface, the idea of a smart contact lens has real merit, and that begins with its potential to improve our well-being.

A picture of health

Over the past decade or so, scientists have made great advances with technologies that can provide different measures of our health by sampling our bodily fluid. Sweat is a great example of this. Researchers around the world are working on patches equipped with sensors and electronics that can be worn on the skin to analyze the makeup of our sweat, working out which chemicals are present and which ones are not.
