Now, This Is Cool

A science and technology story: researchers have discovered a type of molecule that can detect glucose levels in human tears. They are working on a way to incorporate the substance into contact lenses. A small, translucent dot in the wearer’s field of vision would change colors depending on the glucose levels, creating a continuous monitor instantly accessible to the user. No more sticking yourself and using blood testing gear.
They are working on a way to check cholesterol levels in the same way. (But do cholesterol levels change quickly enough to merit including them in contact lenses?)
