As technology marches on, we get innovations like this that reduce medical waste, reduce user discomfort, and increase the control diabetics can exercise over their blood sugar.
Color-Changing Contact Lenses Help Diabetics Keep Tabs on Glucose Levels | Ecouterre
"A biochemical engineer at the University of Western Ontario has developed contact lenses that change color in response to spikes and dips in the wearer’s glucose levels.
. . .
The nanocomposite hydrogel lenses, which could render those pesky e-waste-generating blood-glucose meters obsolete, will allow diabetics to monitor potentially life-threatening variations in their sugar levels without missing a thing. (Another upside: They’re ouch-free.)"
Sounds like a good idea ... except for the fact that I cannot stand even the thought of putting anything in my eye; I would rather stay with a few pinpricks every day. (When my wife wore contact lenses I could not even watch her take them out or put them in. I may have something to do with having worn glasses since I was 8 years old.) Now if the same technology could be made into a skin patch, like on the back of the hand, that would be workable.
