Researchers have used 3D printing technologies to create light receptors on a hemispherical surface which could pave the way for future bionic eyes.
Academics from the US University of Minnesota said the invention is a “significant step” towards the creation of synthetic eyes which could either restore sight for the blind or improve levels of sight for the visually impaired.
3D printing on straight, flat surfaces is common, but attempting to print delicate components reliably on curved surfaces represents a challenge. The team began their journey with a hemispherical glass dome, which approximates the spherical surface of organic eyes.
