Special Contact lenses to monitor blood sugar

A team of researchers at the University of Maryland’s Biotechnology Institute headed by Dr. Chris Geddes has developed special molecules with the ability to identify glucose at very low levels that can be integrated in contact lenses to detect the amount of glucose in the tears that is approximately 1/10th of the total present in the blood. With such contact lenses, there will be no need of any extra device. These contact lenses will show the results in the form of a dot in the wearer’s area of vision by changing colors to point out low or high blood sugar levels. Anyway diabetics need to sit back a while until the special lenses undergo complete testing process to become commercially available.
