The hardware behind this invention is a spherical curved LCD display that can fit into a contact lens, developed by Ghent University's Centre of Microsystems Technology in Belgium.
"This is not science fiction," chief researcher for the project Jelle De Smet told the Telegraph. "This will never replace the cinema screen for films. But for specific applications it may be interesting to show images such as road directions or projecting text messages from our smart phones straight to our eye.”
These lenses may hit the market within the next few years. In an upgrade from previous models, a new LCD display allows the entire curved surface of the lens to be used.
Earlier versions were based on LEDs, where the display resolution would be limited to only a small number of pixels.
