Miikka Terho, a man with genetic blindness, has been able to recognise and detect different letters after having an electronic chip inserted in his eye.
The chip was inserted into his eye far behind the retina. The chip works by processing the light that enters the eye, and it converts the light into lots of electrical impulses that are sent up the optical nerve to the brain.
The trial was carried out on 11 people in Germany by professors from the University of Tuebingen. Most of the recipients had conditions that were too advanced, but Mr Terho was able to walk around a room freely and approach people, as well as reading his name, which had been purposefully misspelled.
This new technology is exciting news for many people affected by blindness.
