A new development in contact lens technology could see the end of diabetes sufferers having to constantly check their blood sugar levels.
Researchers at the University of Western Ontario, Canada, have created hydrogel contact lenses with integrated nanoparticles which chemically react to glucose found in tears, allowing doctors to monitor blood sugar.
Jin Zhang, chemical and biochemical engineering professor at the university, told EmpowHer: "There is a need for a non-invasive measure to detect the levels of glucose, instead of taking a blood sample."
It is believed that the new solution, which is at the trial stage, could allow patients with diabetes to be alerted to any changes in their glucose levels by small tint changes in the contact lenses.
A home testing kit was recently developed to allow contact lens wearers to find out if they could be at risk of developing the hereditary illness age-related macular degeneration, which is the most common form of blindness in over 50s.
