Does anyone prefer the glasses could have contact lenses that display videos and still detect health problems?
More than that, contact lenses that could be manufactured using a 3D printer.
Most current 3D printers work with plastic or metal to create simple objects. But Michael McAlpine and his colleagues at Princeton University, US, have developed a 3D printer that makes a contact lens of five layers, incorporating LEDs to create a screen.
The contact lens is made of multiple polymer layers with incorporated electronics including: light emitting diodes (LEDs) on the nanoscale with the wiring made of silver nanoparticles and organic polymers.
