Those suffering from retinitis pigmentosa, an inherited form of blindness, have been given a glimmer of hope by the UK's National Health Service.
A successful trial now means that NHS England will carry out procedures to implant "bionic eyes" into ten patients from around the UK, restoring some of their sight.
Five patients from the Manchester Royal Eye Hospital and five from Moorfields Eye Hospital in London will be fitted with the Argus II retinal implant in the new year, which uses a mounted camera to capture light and send a signal to the brain.
It allows the wearer to discern between light levels and, in some cases, even make out large lettering.
"I'm delighted that our pioneering research has provided the evidence to support NHS England's decision to fund the bionic eye for the first time in patients," said Professor Paulo Stanga from the Manchester Royal Eye Hospital.
"It surpassed all of our expectations when we realised that one of the retinitis pigmentosa patients in Manchester using the bionic eye could identify large letters for the first time in his adult life."
