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.
