Researchers are now developing electronic contact lenses with a glucose sensor that can monitor blood sugar levels wirelessly.

The initiative by Microsoft Research and the University of Washington, would be a big help to people with Type I diabetes, who must keep a check on their blood sugar on a daily basis by actually drawing blood several times a day.

Although tear film can show blood sugar levels but getting it from the eye is extremely difficult.

A contact lens designed to analyze enzymes from glucose in tears could solve that problem.

`Professor Zhang`s lab has been largely using nanostructured optical probes embedded in hydrophilic hydrogen lenses, and they`ve had some successes recently,` Discovery News quoted Microsoft Researcher Desney Tan as telling Gizmag.

`As the enzyme interacts with the tear fluid, specific measurements are made by observing the change in current measured by bio-compatible electrodes on the contact lens,` Tan added.
