>>Contact Lenses That Change Color To Alert Diabetics of Glucose Levels:<<

(Great invention)
There is great news for diabetics . A revolutionary technology has came into being to help them measure blood sugar levels without drawing blood daily. It 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. Developed by biochemical engineering professor Jin Zhang at the University of Western Ontario.
