Special contact lens "may help diabetics"

Special contact lens "may help diabetics"

A new type of contact lens may help people suffering from diabetes to detect whether they have enough glucose in their body, according to reports.

University of Western Ontario Department of Chemical and Biochemical Engineering has developed a glucose biosensor integrated with a disposable nanostructured contact lens.

The facility claims this provides a safe, convenient and non-expensive glucose sensing device, while the biosensor provides an efficient and non-invasive solution for monitoring blood glucose.

"These patent pending contact lenses can be worn by diabetics who can colorimetrically see changes in their contact lens colour or other fluorescence-based properties, giving an indication of tear and blood glucose levels," the experts said.

It follows a study presented at the 2010 Annual Meeting of the Association for Research in Vision and Ophthalmology, which claims that a special contact lens may reduce the progress of myopia, or nearsightedness, by fully correcting the central vision.
