A smart contact lens for diabetes sufferers
Globally, an estimated 285 million people have diabetes – a chronic disease that occurs when the pancreas does not produce enough insulin, or when the body cannot effectively use the insulin it produces. Its incidence is growing rapidly, and by 2030, the number of cases is predicted to almost double. By 2050, as many as one in three U.S. adults could be affected if current trends continue.
To keep their blood sugar levels under control, sufferers need to constantly monitor themselves. This can involve pricking their finger to get a blood sample, two to four times per day. For many people, managing this condition is therefore a painful and disruptive process.
To address this problem, Internet giant Google has announced it is developing a smart contact lens. This wearable tech will measure glucose levels in tears, using a tiny wireless chip and miniaturised sensor, embedded between two layers of soft contact lens material. When glucose levels fall below a certain threshold, tiny LED lights will activate themselves to function as a warning system for the wearer.
Google admits it is still "early days" for this technology, but there is clearly great potential for improving the lives of diabetes sufferers around the world. To achieve their goal, they intend to partner with other technology companies who have previous experience of bringing products like this to market. You can read more at the Google Official Blog.
