Enhancing contact lenses with electronics seems to be a topic that has gained research interest. Smart contact lenses for health and head-up displays article the litany of research projects underway in the field of contact lens enhancement. Sensimed has already contact lens with surface-mounted strain gauge to assess glaucoma risk. Those medical measuring lenses have lacked display.
I wrote to years ago at Augmented Reality in a Contact Lens posting that researches are developing a new generation of contact lenses built with very small circuits and LEDs.
The news today tells that the idea of those contact lenses has progresses. Electronic contact lens displays pixels on the eyes tells that the first contact lenses containing electronic displays into the eyes of rabbits as a first step on the way to proving they are safe for humans. US and Finnish team says that they have demonstrated the operation of a contact lens display powered by a remote radio frequency transmitter in free space and on a live rabbit.
The test lens was powered remotely using gigahertz-range radio-frequency energy. The power transmitter was placed ten centimetres from the rabbit’s eye and RF energy was picked up on the lens with 5-millimetre-long antenna printed on the lens. The test lens had only one pixel.
Now we have to wait displays with good resolution become available some day. Maybe some day they can replace some larger displays…
