The contact lenses are used world wide by millions in a comfortable way. Do think I could be our future display for everything and monitor our body elemental content? I think there are many problems like dry eyes and micro-contaminants exist in atmospheric air may affect these sensors and bring fault readout !! what do you think?
Here are some details about that idea:
Tears exist with much of the same chemical makeup as blood, so contact lenses are a solution to show what is going on inside a patient’s body without actually going inside the body. Contact lenses are used by more than one hundred million people and have existed for decades, giving users a comfortable method of existing with a continuous sensor.
As a receiver the lens could act as a display for the user, with cell phone towers beaming information to a unit in the user’s pocket. An augmented reality application is the most feasible use for a lens receiver. Long term Babak says that screens exist to bring information to the retina, and many screens could be consolidated into one display per human being.
The semiconductor industry is constantly churning out smaller sensors allowing the lenses to collect and disperse information. Some sensors are down to 50 nanometers, approaching the size of a single cell in the body. Using miniaturization technology along with flexible sensor technology Babak is developing the contact lens sensors.

Maybe they make it multilayer contact lens, so refractive index change do the Job!!
