Researchers say they’ve figured out how to 3D print AR contact lenses.
Smart contacts are a cool idea but a big technical challenge is combining low-power displays with a high-contrast color material to see information. South Korean researchers say their solution is to 3D print micropatterns without needing any kind of voltage, making it ideal for smart contacts.
The researchers say they expect AR navigation to be the main application for this tech, where directions unfold right on your eyeball. Playing Pokemon Go was also cited as one potential use case. Even so, smart contacts still need to be deemed safe before any of this becomes a reality.
