Color Changing Contacts for Diabetics

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 secret: Ultra-teeny nanoparticles that react chemically with glucose molecules in tears to produce a shift in hue.

The nanocomposite hydrogel lenses will allow diabetics to monitor potentially life-threatening variations in their sugar levels without missing a thing.
