A group of researchers from University of Washington and Aalto University designed, built, and tested each subsystem of a single-pixel contact lens display. This contact lens comprises a light emitting diode (LED), an antenna, an integrated circuit (IC) for power harvesting and LED control, and a polymer substrate with electrical interconnects. In their test, the lens was controlled by a remote radio frequency transmitting data from the lens. The new technology projects text and images before the person’s eyes. One of the main current disadvantages; the lens is made of a hard plastic that doesn’t allow the eye to breath, so it cannot be worn for a long time. The researchers noted that their long-term goal is to create a display lens that can be comfortably worn.
