Glaucoma monitoring contact lenses crafted at UC Davis

August 5th, 2008 by

Far from the first circuit-laden contact lens we’ve laid eyes on (ahem), researchers at UC Davis have more than bragging rights in mind with their “smart” contacts. The devices are infused with a “pattern of conductive silver wires, which could be used to measure pressure inside the eye.” The material, dubbed polydimethylsiloxane (PDMS), would boast antimicrobial properties and could enable scientists to better study glaucoma. How so? By sending pressure data to computers sans wires. Better still, the contacts also include the ability to automatically dispense medication into the eye, making this beneficial in more ways than one. The creators are expected to apply for approval to begin testing the lenses in humans here shortly, and barring any unforeseen (sorry, totally unintentional there) setbacks, we would hope these could be put to use within the next few years.

Researchers put circuits on contact lenses, freak out rabbits

We’ve seen plenty of newfangled contact lenses in the past, but it looks like a team of researchers at the University of Washington may have outdone them all, with their latest creation promising not only heads-up displays, but “superhuman vision.” That’s apparently possible thanks to a combination of lights and circuits, which they’ve managed to cram onto lens no larger than your average contact — though it doesn’t even do so much as light up in its current state (that’s promises “soon”). Naturally, the researchers have tested the lenses on rabbits instead of themselves, which they say have shown “no adverse effects” after wearing the lenses for upwards of 20 minutes, although we’ll just have to wait and see if they feel the same way after the researchers flip the switch on ‘em.
