Thursday, 27 May, 2021 - 06:45 FILE - A woman receives an eye exam at the Care Harbor/LA free clinic in Los Angeles, September 27, 2012. Reuters Paris - London - Asharq Al-Awsat Thanks to an innovative technique that combines gene therapy and light stimulation, the vision of a completely blind 58-year-old man has been partially restored. The man, whose identity has not been revealed, lives in Brittany, France, and was treated in Paris. He was diagnosed with retinitis pigmentosa - which leads to the death of light-sensing cells on the surface of the retina - 40 years ago. According to BBC, this condition affects more than two million people worldwide, and although complete blindness is rare, the man has had no vision for the past two decades.

The protein is naturally produced by algae to help them detect light.
