Contact lenses with a display

Belgian scientists have successfully developed a LCD display for contact lenses, but this technological advancement is currently still in its start-up phase. According to the article (Dutch only) on the website Fresh Gadgets it is, for now, not yet possible to see information with the contact lenses; as the human eye cannot focus properly on what is displayed due to the short distance between the eye and the lens. However, other forms of practical application could be thought of as well. For instance, the lenses can automatically react to sunlight and turn into sunglasses or they could change the colour of the wearer’s irises.
