sugar sensing contact lenses for diabetics

The Google lab is renowned for its unusual and futuristic projects and its most recent development doesn’t disappoint- sugar sensing contact lenses that could help diabetics manage their blood sugar levels.

Diabetes is a condition that affects 1 in every 19 people on the planet, meaning that a large proportion of the population face the daily challenge of trying to keep their blood sugar levels under control. Keeping these sugar levels under control is crucial to avoiding short and long term complications such as damage to the eyes, kidneys and heart.

So, how does this seemingly genius invention work? Well, it measures the glucose levels in someone’s tears “using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material”, say co-founders Brian Otis and Babak Parvis.

Whilst prototypes are still undergoing clinical tests, this new breakthrough could mean the end of the somewhat painful prick that diabetics have to undergo on a daily basis. The convenience and ease of these sugar sensing contact lenses may also replace trickier equipment such as glucose sensors and therefore encourage people to check their blood glucose levels more regularly.

Developments such as these are always very exciting and can potentially have a very positive effect on the lives of millions. Not only this, but travelling with diabetes could become a lot easier. There would potentially be less need to travel with delicate equipment for example.


What do you think of these sugar sensing contact lenses? Would it be something that you would try or is this a little too futuristic?
