Glucose-tracking smart contact lens is comfortable enough to wear
Alphabet’s autofocusing contact lens won’t be tested in 2016
Scientists build soft, transparent contact lens displays with nanomaterials
Of the contact lens display prototypes that we've seen so far, few if any are focused on comfort -- a slight problem when they're meant to sit on our eyeballs. A collaboration between Samsung and multiple universities may solve this with display tech that's meant to be cozy from the start. By putting silver nanowires between graphene layers, researchers have created transparent conductors that can drive LEDs while remaining flexible enough to sit on a contact lens. Current test lenses only have one pixel, but they're so soft that rabbits can wear them for five hours without strain. Scientists also see the seemingly inevitable, Glass-like wearable display as just one development path -- they're working on biosensors and active vision correction. While there's still a long way to go before we reach a cyberpunk future of near-invisible displays, we may finally have some of the groundwork in place.

Researchers devise contact lens with built-in LCD (video)
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.
