New Contact Lense Technology for People with Diabetes!

Scientists over at the University of Western Ontario is in the process of developing new contact lenses that could help people with diabetes determine their sugar levels by watching themselves in the mirror and see the change of eyeball color.

I think this definitely is something that would help people with diabetes a lot as they won’t have to carry around a tester kit with them everywhere.  Plus, this might be even better if the new contact lenses can be worn by people with prescription, kill two birds with one stone.

Diabetics may soon be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colours – replacing the need to routinely draw blood throughout the day.

The non-invasive technology, developed by Chemical and Biochemical Engineering professor Jin Zhang at The University of Western Ontario, uses extremely small nanoparticles embedded into the hydrogel lenses.  These engineered nanoparticles react with glucose molecules found in tears, causing a chemical reaction that changes their colour.
