Clever contact lenses watch for glaucoma even when wearers' eyes are shut
Although there already are "smart" contact lenses that monitor the eyes for signs of glaucoma, the devices are typically only worn when the patient is awake. A new type of contact lens, however, watches over the eyes throughout the night, too.
Developed by scientists at the University of Electronic Science and Technology of China, they're approximately the same thickness as regular contacts, yet each one is made up of five stacked layers of material. An external electromagnetic reader coil and a Tesla meter are able to pick up signals from the sensors in the BCL, converting them into measurable CIOP and MEM data formats. And importantly, in rabbit tests, the breathable contacts produced no corneal inflammation or other eye damage even after being worn nonstop for one week.
