The possibilities for these smart contact lenses is just unimagineable..
A snipit from the article you found... nice find:
"In addition to measuring glucose levels, the lenses may potentially detect other indicators of illness. Thomas Quinn, head of the American Optometric Association’s contact lens and cornea section, explained to MIT’s Technology Review that tears also contain lacryglobin, a chemical “that serves as a biomarker for breast, colon, lung, prostate, and ovarian cancers.” It could be particularly useful to monitor the lacryglobin levels of cancer patients who are in remission, Quinn added.
Quinn also suggested that another application for smart lenses could be drug delivery: “f a lens could dispense medication slowly over long periods of time, it would be better for patients than the short, concentrated doses provided by eye drops,” Technology Review reported. Research has indicated, however, that this function will be difficult to achieve."
