Regular blood glucose measurement is a real pain for diabetics. Professor Jin Zhang from the University of Ontario gives a practical and workable solution. His idea was developed based on some microparticles whose composition reacts to the glucose levels detected in tears.
By incorporating these microparticles into a hydrogel contact lens, he was able to build a unique tool for continuous observation. The contact lens changes colour when exposed to high levels of glucose. In this way, the patient does not have to do anything more than observe the colour of the contact lens in a mirror.
This innovative contact lens is currently in the research stage and alternative methods of observation are also being tested
For example, the lens may change colour in the periphery or create an image in the patient's field of vision so that it is immediately perceptible.
