Another day, another step towards technologically tricked out contact lenses. The latest development comes from researchers at the Centre of Microsystems Technology at Ghent University, who've developed a prototype lens with an embedded, spherical curved LCD that isn't limited to a paltry amount of pixels. As opposed to LED-based solutions which could only muster a few pixels, the newly-developed screen can pack enough to display graphics that cover a contact. In its current form, the display can show simple patterns, and demonstrates the technology with a simple dollar sign. What appears on the lens wouldn't be visible to folks who wear it, however, since eyes can't focus at such a close range. Despite the limitation, researchers are trying to tackle the focusing issue and are assessing the feasibility of a version that would effectively act as a heads-up display. In the future, the tech could be leveraged for medical purposes, such as controlling light transmission to the retina when the iris is damaged, cosmetic uses and -- you guessed it -- HUDs. With the technology's foundation established, it's expected that real-world applications are potentially a few of years away. Hit the jump to catch a video of the tech in action.
