Diabetics know that keeping on top of the body’s glucose level is vitally important. Bad things happen when the level dips too low, or spikes too high, and constant monitoring is the key to maintaining control. Technology is often leveraged to handle this chore, but nothing I’ve seen to date makes more sense than these color-changing contact lenses.
The lenses use special nanoparticles that change color to reflect the glucose level in tears. They are, in essence, a constant glucose monitor that requires no effort from the diabetic. Just pop them in and go. I hope we see these lenses hit the market, something that unfortunately doesn’t always happen with medical technology.
