Google Smart Contact Lens

No, it's not an eyeball-mounted version of Glass. Instead, the Google Smart Contact Lens aims to help those with diabetes manage their disease by using a tiny wireless chip and sensor that are embedded in the contact and constantly measure the glucose levels in the wearer's tears. Obviously they're still in the testing phase — they're even considering integrating tiny LED lights to indicate when levels spike or fall below certain thresholds — but for those suffering with diabetes, it can't hit the market fast enough.
