Belgian researchers are developing curved LCD displays that can fit onto contact lenses.
The minuscule screens are intended to let the user see information such as text messages and images.
"Now that we have established the basic technology, we can start working towards real applications, possibly available in only a few years," said Professor Herbert De Smet.
"By using new kinds of conductive polymers and integrating them into a smooth spherical cell, we were able to fabricate a new LCD-based contact lens display."
The new technology means the entire surface of the lens can be used to project images, unlike previous contact lens displays, which are limited to a few small pixels.
The researchers believe that the lenses could eventually be developed with the same detail as a television screen.
