Google is testing a ‘smart contact lens’ fitted with a wireless chip to measure glucose levels in tears.
While Google has said it is still early days for the technology, the firm has revealed that it has already completed multiple clinical research studies.
The tiny wireless chip is paired with a miniaturised glucose sensor embedded between two layers of lens material. Google is also hoping to add a tiny LED light that could indicate when glucose levels have crossed above or below certain thresholds.
“Although some people wear glucose monitors with a glucose sensor embedded under their skin, all people with diabetes must still prick their finger and test drops of blood throughout the day. It’s disruptive, and it’s painful. And, as a result, many people with diabetes check their blood glucose less often than they should,” explained Google on its official blog.
Google said it is testing prototypes that can generate a reading once per second.
