Smart contact lenses being developed for medical and recreational use

Daily Mail : Instead of toting around bulky devices to monitor health and wellness, browse the internet, or watch videos, people may one day be able to just pop in contact lenses. A number of projects are in the works, among them one by researchers at the University of South Australia who have been developing a prototype that integrates a biocompatible, conducting polymer within a hydrogel. The researchers have succeeded in containing the electrical current within the hydrogel, which is essential to prevent the current from coming into contact with the wearer’s eye. A lens made from such a material could act as a simple sensor, such as for detecting blood glucose, or as a full-blown electronic display. Other potential uses for smart lenses include gathering data about the wearer’s environment, such as the presence of allergens like grass or tree pollen, and reading QR codes or barcodes.
