Researchers from Oxford University say they have made a breakthrough in developing smart glasses for people with severe sight loss.
The glasses enhance images of nearby people and objects on to the lenses, providing a much clearer sense of surroundings.
Nearly two million people in the UK have a sight problem which seriously affects their daily lives.
