Contact lenses that can receive SMS


Soon gone are the days when only mutants those that have special powers can see messages in their eyes as researchers at Ghent University in Belgium have been able to produce a spherically curved LCD unit which may find its way into a contact lens. The LCD can handle projected images using wireless connectivity. The fundamental technology behind this concept already existed to a certain extent, but the researchers at the university’s Center of Microsystems Technology have been able to take it a step further and allow use of the whole surface of the curved lens. “Now that we have established the basic technology, we can start working towards real applications, possibly available in only a few years,” according to Professor Herbert De Smet.  That is an impressive, if ambitious, prediction.  However, at the rate that technology has been advancing, we are not going to contest that objective at all. Some potential applications would be remarkably simple, such as lenses that would adjust pigmentation and serve as sunglasses. Other applications might involve conveying text messages or navigation instructions. The possibilities do not stop there, this technology may offer additional methods to correct certain vision impairments by controlling light transmission to the retina. Those that like to influence their own mood may be able to adjust coloration and choose to see the world through rose-colored lenses.
