Google Shows Off Smart Contact Lens
Google has shown off a “smart contact lens” that it says can provide feedback to the wearer about their blood sugar levels. It’s aimed at people with diabetes who routinely need to keep control of their blood sugar levels, often with regular blood tests.
Google says that it has now developed the contact lens based on embedded miniature electronics to test the natural eye fluids as a base for the blood sugar levels.
The company says that it is testing a smart contact lens that’s built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material.
At the moment, the product is speculative, and the exact mechanism for alerting the wearer of problems has yet to be refined.
There is precedent for embedding technology into contact lenses, as back in 2008, researchers at the University of Washington were able to embed a display screen into a contact lens.
Combining the two technologies would enable a contact lens to act as a medical monitor, and display vital information right in front of the wearer’s field of vision where it would be impossible to overlook.
