They're not the only ones working on contact lenses that measure blood sugar levels, but researchers at the University of Maryland's Biotechnology Institute led by Dr. Chris Geddes seem to have taken the technology further than most. They've reportedly developed special molecules that can detect glucose at very low levels which, when incorporated into a pair of contact lenses, should be adequate for detecting the amount of glucose in the wearer's tears -- which is about one tenth the amount in blood. What's more, unlike previous versions of the technology -- which required an additional device to read the results -- Geddes' new lenses will be able to simply display the results as a dot in the wearer's field of vision, changing colors to indicate low or high blood sugar levels. A lot more pleasant than the pin prick most diabetics now use to monitor their blood sugar to be sure, although as you can no doubt guess, more testing is needed before the lenses can be released into the wild.
