Google Unveils ‘Smart Contact Lens’ To Measure Glucose Levels For Diabetics

The most difficult part about diabetes is to keep a check on the level of glucose in the bloodstream. If the constant worry of thinking about it nearly all the time isn’t ‘prickly’ enough, testing methods only make it worse. This is usually done by employing tiny pin pricks that draw blood which is then collected on test strips and tested in the electronic equipment to get a reading. It seems diabetes patients may a have a savior in this regard. That’s right; Google has unveiled smart contact lens to measure glucose levels. Let’s see how technology comes to the rescue.

It is no surprise that the research lab behind the fresh concept is Google X- the same lab that gained recognition for Google Glass and Google self-driving cars. Smart contact lens comes equipped with a miniaturized glucose sensor and a tiny wireless chip that lie between two lenses.

Blood sugar is measured each second by monitoring its levels in the tears that wash over the eye. This data can then be wirelessly transmitted. What’s more, Google has planned the development of small LED lights that would be integrated in the system and flash as soon as the levels cross set limits.

Google is careful about ensuring that the data from smart contact lens is not manipulated. Otherwise, it could result in patients injecting inappropriate amounts of insulin based on inappropriate results on offer. Moreover, Google has employed safeguards to overcome technical problems such as overheating by incorporating technology similar to a circuit breaker.

Interestingly, the bits of technology made use of are either as tiny as specks of glitter and as thin as a strand of hair. Google claims that it’s working in corroboration with the FDA to help bring this kind of technology to the market for the benefit of doctors and patients, alike.

There’s no doubt that there is nothing like smart contact lens available in the market right now, but Google believes it’s still early days and aims to further improve.
