Eye-Pods

Researchers at the University of Washington–Seattle and at Sandia National Laboratories, in Albuquerque, have unveiled the ­latest advance in headâ''up displays: a ­contact lens with an imprinted electronic circuit and red LEDs. Future versions will superimpose images over the user’s view of the world and include ­wireless ­transceivers for two-way ­communication and solar cells for power. Now what’s to stop future ­generations of students from furtively scanning crib sheets when the illicit notes are on displays built into their contact lenses?
