Smart Contact Lens for Glucose Monitoring

Google and Novartis/Alcon have agreed to collaborate upon the development of a smart contact lens for medical use…. 

The product has the potential to not only address ocular conditions but also glycemic levels. Using non-invasive sensors, the lens is designed to analyze tear fluids in the eyes to provide constant measurements of blood glucose levels. The data will be transmitted wirelessly onto a mobile device, where the levels are continuously monitored. LED lights may be incorporated into the design of the product to signal patients that glucose levels have gone above or below the recommended thresholds. In addition to glycemic monitoring, there are other potential uses that can come out of the smart lens. The lens can be a potential fit for patients with presbyopia, which helps restore the eye’s natural autofocus by implanting the lens directly onto the eyes.

With the non-invasive sensors, microchips, and other miniaturized electronics embedded on the contact lens, this could be the start of further miniaturizations of electronics adapted for the human body.

Practice Pearls:

  • Using non-invasive sensors, the lens is designed to analyze tear fluids in the eyes to provide constant measurements of a person’s blood glucose level.
  • The glucose levels will be transmitted wirelessly onto a mobile device, where the levels are continuously monitored
  • The lens can be a potential fit for patients with presbyopia, which helps restore the eye’s natural autofocus by implanting the lens directly onto the eyes.
