Seeing is believing

Posted by on 19 July 2011

285 milllion people are visually impaired. Of the 285 million, 39 million are blind and 246 million have low vision. Stephen Hicks from the University of Oxford talks here about how they are trying to combat blindness. Their exhibit Interactive bionic vision shows how they are tackling blindness in two different ways by firstly restoring sight for some people and improving sight for others. To restore sight in some who have only a few layers of their retina damaged, a chip can be implanted into the back of the eye to help it sense light. Stephen Hicks and his team have also developed a special pair of glasses linked to a computer to help improve some people’s sight. Listen to the following podcast to find out more about this.
