Contact lenses under development are designed to use tiny sensors to monitor the biochemistry of the eye surface and provide readings on measurements such as blood glucose levels, cholesterol, temperature, inflammation, infection or fatigue. Amazingly, the results would be displayed right on the lens for the wearer to see. See Contact Lens Monitors Health :
“The surface of the human eye has a wealth of information about the human body,” Parviz said. “In a very noninvasive way, you can monitor what’s going on inside the body without going inside.”
Don’t want it displayed on your contact? Theoretically, the information could be beamed to your cell phone and e-mailed to you, Parviz said.
So far, researchers have been able to build contacts with tiny antennas, radios and light sources. The components are so small they resemble a grainy powder.
To assemble the lenses, researchers cut shapes into the contact lens base, submerge it into a liquid and “wash” the tiny components over it. The different-shaped parts fit like pieces of a puzzle into the base. The pieces are locked into place by a drop in temperature.
Researchers at the University of Washington are developing the technology, with financial support from the National Science Foundation and Microsoft.
Initial testing is being done on rabbits. I wonder what they think is going on.
